A GPS satellite orbits at an altitude of 20,200 km above the surface of the earth. What is the speed of the satellite? Recall that RE= 6.37 x 10^6 m

Answers

The speed of the GPS satellite can be calculated using the following formula:

How to calculate GPS satellite ?

v = √(GM/r)

where G is the gravitational constant, M is the mass of the Earth, r is the distance between the center of the Earth and the satellite, and v is the speed of the satellite.The distance between the satellite and the center of the Earth can be found by adding the radius of the Earth to the altitude of the satellite:

r = RE + h = 6.37 x 10^6 m + 20,200,000 m = 2.06 x 10^7 m

The mass of the Earth is M = 5.97 x 10^24 kg, and the gravitational constant is G = 6.67 x 10^-11 Nm^2/kg^2. Substituting these values into the formula, we get:

v = √(GM/r) = √((6.67 x 10^-11 Nm^2/kg^2)(5.97 x 10^24 kg)/(2.06 x 10^7 m)) ≈ 3,870 m/s

in a frictionless setup, two block of different masses are laying on two incline planes with different slopes and joined together by a pulley (see figure). find the acceleration of each block and the tension in the rope. also write the criteria (or equation) needed to be satisfied for block 2 to be moving down its incline plane.

Answers

Answer:

Explanation:

The problem you're describing involves two blocks connected by a rope over a pulley, with each block resting on a separate incline plane. The acceleration of each block and the tension in the rope can be determined using the principles of dynamics and conservation of energy.

Let's call the masses of the two blocks m1 and m2, the incline angles of the two planes θ1 and θ2, and the acceleration of each block a1 and a2.

The net force on each block is given by the sum of the gravitational force, the normal force, and the tension in the rope.

For block 1:

m1 * g * sin(θ1) - m1 * a1 = T

For block 2:

m2 * g * sin(θ2) - m2 * a2 = -T

where g is the acceleration due to gravity and T is the tension in the rope.

From these equations, we can see that the tension in the rope is equal in magnitude but opposite in direction for each block. The acceleration of each block can be found by rearranging the equations and solving for a1 and a2.

The condition for block 2 to be moving down its incline plane is that the net force on the block must be in the direction of motion, which means that the tension in the rope must be less than the gravitational force acting on the block. This can be expressed as:

T < m2 * g * sin(θ2)

Here is a definition of each variable in the problem:

m1: mass of block 1

m2: mass of block 2

θ1: incline angle of the first plane

θ2: incline angle of the second plane

a1: acceleration of block 1

a2: acceleration of block 2

g: acceleration due to gravity

T: tension in the rope

(b) When you have traveled only half the distance in part a, is your speed 6.0 m/s, greater than 6 m/s or less than 6 m/s? Support your answer with calculations.

Answers

a) Travelled 20.57 meters before coming to a stop.

b) When travelled half the distance, the speed is 2.6 m/s, which is less than 6 m/s.

What does speed mean?

Speed is a measure of how fast an object is moving, without regard to the direction of its motion. It is defined as the distance travelled by an object per unit of time. Speed is a scalar quantity, which means it only has magnitude (i.e., numerical value) and not direction. The standard unit of speed is meters per second (m/s) in the International System of Units (SI), although other units such as kilometres per hour (km/h) and miles per hour (mph) are also commonly used. It can be calculated as the ratio of distance traveled by an object to the time taken to cover that distance.

For example, if a car travels 100 meters in 10 seconds, its speed can be calculated as 100 meters divided by 10 seconds, which equals 10 meters per second. Speed can also be constant, if the object is moving at a constant rate without changing its speed, or variable, if the object's speed changes over time.

(a) To determine how far travelled before stopping, use the kinematic equation:

[tex]v^2 = u^2 + 2as[/tex]

where,

v = final velocity (0 m/s, since you come to a stop)

u = initial velocity (12 m/s)

a = acceleration (-3.5 m/s^2, since decelerating)

s = distance traveled (unknown)

Rearranging the equation to solve for s, we get:

[tex]s = (v^2 - u^2) / (2a)[/tex]

Substituting in the known values, we get:

[tex]s = (0 - (12 m/s)^2) / (2*(-3.5 m/s^2)) = 20.57 m[/tex]

Therefore, travelled 20.57 meters before coming to a stop.

(b) To determine speed, travelled half the distance, use the kinematic equation:

[tex]s = ut + 0.5at^2[/tex]

where,

t = time elapsed (unknown, but  use the fact that have travelled half the distance)

s = distance traveled (half of 20.57 m = 10.285 m)

u = initial velocity (12 m/s)

a = acceleration (-3.5 m/s^2)

Substituting the known values,

[tex]10.285 m = (12 m/s)t + 0.5(-3.5 m/s^2)t^2[/tex]

Simplifying and rearranging, a quadratic equation is obtained:

[tex]1.75t^2 - 12t + 10.285 = 0[/tex]

Solving  t using the quadratic formula,

t = 2.52 s (rounded to two decimal places)

Now, to find your speed at this point, we can use the kinematic equation:

[tex]v = u + at[/tex]

Substituting the known values,

[tex]v = 12 m/s + (-3.5 m/s^2)(2.52 s) = 2.6 m/s[/tex]

Therefore, when travelled half the distance, the speed is 2.6 m/s, which is less than 6 m/s.

What will happen to an acceleration if the mass of an object is tripled, but the force is kept the same?

Answers

If the mass of an object is tripled while the force acting upon it is kept constant, the acceleration of the object will be reduced to one-third of its original value.

This can be explained using Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.

In this scenario, the force is held constant, but the mass is increased by a factor of three. As a result, the acceleration will decrease by a factor of three, since the same force is now acting on a much heavier object. Therefore, the object will experience a lower acceleration than before, making it harder to move or change its speed or direction.

Answers

It is demonstrated that for each k, there exists a set of k positive integers whose difference has an even number of prime components, counted with multiplicity.

Let's construct the set of positive integers using the following algorithm:

Start with the first k prime numbers: 2, 3, 5, 7, 11, ..., p_k.

Define the i-th integer in the set as the product of the first i prime numbers: a_i = 235*...*p_i.

Claim: For any two integers in the set, their difference has an even number of prime factors, counted with multiplicity.

Proof:

Let a_i and a_j be two integers in the set such that i < j. We want to show that the difference a_j - a_i has an even number of prime factors, counted with multiplicity.

Notice that a_j - a_i can be written as:

a_j - a_i = 235*...p_i(235*...*p_j/2 - 1)

The first term on the right-hand side has i prime factors, and the second term has an odd number of prime factors. To see why the second term has an odd number of prime factors, notice that all the prime factors of 235*...p_j are also prime factors of 235...*p_i, so they cancel out in the difference.

a_j - a_i has i prime factors plus an odd number of prime factors, which is an even number of prime factors. This completes the proof.

A hot rod can accelerate from 0 to 60 km/h in 7.5 s. (a) What is its average acceleration, in m/s2, during this time? (b) How far will it travel during the 7.5 s, assuming its acceleration is constant? (c) From rest, how much time would it require to go a distance of 0.40 km if its acceleration could be maintained at the value in (a)?

Answers

Average acceleration is a) 2.22 [tex]m/s^2[/tex] b) hot rod travels 78.4 m c) time is 20 seconds

(a) To find the average acceleration, we need to use the formula: average acceleration = change in velocity / time.

First, we convert 60 km/h to m/s:

60 km/h x 1000 m/km x 1 h/3600 s = 16.67 m/s

So the change in velocity is:

16.67 m/s - 0 m/s = 16.67 m/s

And the time is:

7.5 s

Therefore, the average acceleration is:

average acceleration = (16.67 m/s) / (7.5 s) = 2.22 m/s^2

(b) To find the distance traveled, we can use the formula: distance = initial velocity x time + 0.5 x acceleration x time^2.

The initial velocity is 0 m/s, so the formula becomes:

distance = 0.5 x acceleration x time^2

Plugging in the values, we get:

distance = 0.5 x 2.22 m/s^2 x (7.5 s)^2 = 78.4 m

Therefore, the hot rod will travel 78.4 meters during the 7.5 seconds.

(c) We can use the formula: distance = 0.5 x acceleration x time^2, and solve for time.

Plugging in the values, we get:

0.40 km x 1000 m/km = 400 m

acceleration = 2.22 m/s^2

So the formula becomes:

400 m = 0.5 x 2.22 m/s^2 x time^2

Solving for time, we get:

time = sqrt(400 m / (0.5 x 2.22 m/s^2)) = 20 s

Therefore, it would take 20 seconds for the hot rod to travel 0.40 km with constant acceleration of 2.22 m/s^2.

George is pushing his 20kg son, Jake, on the swing at the park. He pulls his son up to a height of 2m, pauses, and lets him go. What is Jake's kinetic energy before his dad lets go of the swing? What is Jake's kinetic energy at the lowest point? What is Jake's velocity at the top of the lowest point?

Answers

Jake's velocity at the lowest point of the swing is 7 m/s.

What is kinetic and potential energy?

Potential energy is the energy stored in any object or system due to the position or arrangement of its parts. It is, however, unaffected by factors outside of the object or system, such as air or height. Kinetic energy, on the other hand, is the energy of moving particles in an object or system.

To solve this problem, we need to use the conservation of energy principle, which states that the total energy in a system remains constant.

At the highest point, Jake has potential energy (due to his position above the ground), but no kinetic energy (since he is not moving).

As he swings down, his potential energy is converted to kinetic energy, and at the lowest point of the swing, he has the maximum kinetic energy and minimum potential energy. Then, as he swings back up, the process is reversed.

To calculate Jake's potential energy at the top of the swing, we use the formula:

PE = mgh

where m is the mass of Jake, g is the acceleration due to gravity (9.8 m/s²), and h is the height above the ground. Substituting in the values, we get:

PE = (20 kg)(9.8 m/s²)(2 m) = 392 J

This is Jake's potential energy at the top of the swing. At this point, he has no kinetic energy.

At the lowest point of the swing, Jake has converted all of his potential energy into kinetic energy. We can use the conservation of energy principle to find his kinetic energy at this point:

KE = PE

where KE is kinetic energy and PE is potential energy. Substituting in the values, we get:

KE = 392 J

This is Jake's kinetic energy at the lowest point of the swing.

To find Jake's velocity at the lowest point, we can use the formula for kinetic energy:

KE = (1/2)mv²

where v is velocity. Rearranging the formula to solve for v, we get:

v = √((2KE)/m)

Substituting in the values, we get:

v = √((2(392 J))/(20 kg)) = 7.0 m/s

This is Jake's velocity at the lowest point of the swing.

B.
fire rockets to increase force acting in the direction of travel
C.
fire reverse rockets to increase force acting opposite of the direction of travel
D.
open a parachute to increase force acting opposite to the direction of motion of the spacecraft

Answers

A spacecraft can reduce its speed during a trip to Mars by firing reverse rockets to increase force acting opposite of the direction of travel.

option C.

How can a spacecraft reduce its speed?

To reduce the speed of a spacecraft during a trip to Mars, the most common method is to fire reverse rockets, also known as braking thrusters.

These thrusters are used to generate a force that acts in the opposite direction of the spacecraft's motion, slowing it down. This is called a deceleration burn, and it is an important step in the process of entering into orbit around a planet or landing on its surface.

The reverse thrust slows down the spacecraft, reducing its speed and allowing it to be captured by the planet's gravity. This is crucial for the success of the mission and ensures that the spacecraft can be safely guided into orbit or landed on the surface of the planet.

Which is an example of kinetic energy being used?(1 point)

Answers

Answer:

A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.

Explanation:

Walking and running. Cycling. In a windmill, when the moving air hits the blades, it causes rotation which ultimately leads to the generation of electricity. In a hydropower plant, when the kinetic energy of the moving water hits the turbine the kinetic energy of the water gets converted to mechanical energy.

A metallic surface is illuminated by light. There is another metal plate a few cm away, which is held at an electric potential of V the plate is connected to a circuit which measures the current of electrons. When light of wavelength 520 nm is incident on the metal surface, electrons are emitted from the metal surface and absorbed by the second plate, which creates a current. When the potential of the second plate V is increased to Vstop =0.3 V, the current stops. 3.1 Photon energyWhat is the energy of each photon in electron volts?

Answers

The energy of each photon in electron volts is, 2.07.

Stopping potential is the minimum negative voltage applied to the anode to stop the photocurrent. The maximum kinetic energy of the electrons equal the stopping voltage, when measured in electron volt.

Stopping potential = Energy of light wave falling - energy of each photon

Energy of light wave falling = [tex]\dfrac{hc}{\lambda}[/tex]

Energy of light wave falling = [tex]\dfrac{hc}{\lambda}[/tex]

Energy in electron volts for a wave of wavelength 520 nm is, 2.37 eV.

Now,

Stopping potential = Energy of light wave falling - energy of each photon

0.3V = 2.37 - energy of each photon

Energy of each photon = 2.07

use your function to predict the force on the force sensor when the ramp angle is 90 degrees. to make your prediction, assume a cart mass of 2.25 kg.

Answers

When the angle is 90 degrees up, the only force acting in a downward direction is gravitational force, with magnitude mg, where m is mass and g is gravitational acceleration.

m = 2.25 kg, g = 9.8 /s²

F = mg = 2.25 × 9.8

F = 22.05 N.

An item falling freely in a vacuum is said to accelerate gravitationally in physics. This is the constant acceleration brought on just by the gravitational pull.

By putting an object in a vacuum chamber and monitoring the object's speed as a function of time as it accelerates, one can calculate the gravitational acceleration. This is the approach that Galileo popularized.

A. He does work from the moment he touches the book until he lets it go.
B. He does work only while he carries the book across the room.
C. He does work on the book at no time during this process.
D. He does work as he picks up the book and as he lifts it to the shelf.

Answers

Adam lifts a book from the floor, carries it across the room, and places it on a high shelf, he does work only while he carries the book across the room, which is in option B, as work = force x distance.

What is the work done by a person?

According to the equation for work (W = FD), work is only done when a force is applied to an object and it moves some distance as a result of that force, when Adam lifts the book from the floor, he applies force to it, but the book does not move any distance, so no work is done when the object doesn't move, but when he moved the book, work was done.

Hence, he does work only while he carries the book across the room, which is in option B, as he lifts a book from the floor and carries it across the room.

Find the marginal cost functions for each of the following average cost functions. a) AC= 1.5Q + 4 + 460 b) AC = 160 +5+3Q+2Q²

Answers

(a) The marginal cost function is MC = 3Q + 464.

(b) The marginal cost function is MC = 160 + 5 + 6Q + 6Q^2.

What is the marginal cost function?

The marginal cost (MC) of a product is the change in the total cost of producing an additional unit of the product.

(a) AC = 1.5Q + 4 + 460

The total cost (TC) of producing Q units is given by:

TC = AC * Q

TC = (1.5Q + 4 + 460) * Q

TC = 1.5Q^2 + 4Q + 460Q

TC = 1.5Q^2 + 464Q + 460

The marginal cost function is given by the derivative of the total cost function with respect to Q:

MC = dTC/dQ

MC = d/dQ (1.5Q^2 + 464Q + 460)

MC = 3Q + 464

b) AC = 160 + 5 + 3Q + 2Q²

The total cost of producing Q units is given by:

TC = AC * Q

TC = (160 + 5 + 3Q + 2Q^2) * Q

TC = 160Q + 5Q + 3Q^2 + 2Q^3

The marginal cost function is given by the derivative of the total cost function with respect to Q:

MC = dTC/dQ

MC = d/dQ (160Q + 5Q + 3Q^2 + 2Q^3)

MC = 160 + 5 + 6Q + 6Q^2.
