A disc is thrown through the air for 1.5 min with a power output of 12.5 W. How much work is done when throwing the disc?

Answers

Answer:

work = 1125 [J]

Explanation:

To solve this problem we must remember the definition of power, which is defined as the relationship between work and time. The power can be calculated using the following equation:

Power = work/time

Power = 12.5 [w]

work = joules [J]

time = 1.5 [min] = 90 [s]

work = 12.5*90

work = 1125 [J]

Which of these statements did you include in your answer? Check all that apply The two main parts of an atom are the nucleus and the electron cloud. The three subatomic particles of an atom are protons, neutrons, and electrons.

Answers

Answer:

A and B

Explanation:

Both the given statements are true.

An atom has two main parts that include the nucleus and the electron cloud and an atom has three subatomic particles electron, proton and neutron.

The nucleus is consists of neutrons (neutral subatomic particles) and protons (positively charged) and the cloud of electrons consists of electrons which are negatively charged particles.

Hence, the correct answer is "A and B".

x = 50°

Explanation:

52° + 78° + x = 180° (Because of the angle sum property)

=> 130° + x = 180°

=> x = 180° - 130°

=> x = 50°

Answer:

50°

Explanation:

Step 1:

52° + 78° + x = 180°       Sum of a Δ

Step 2:

130° + x = 180°       Combine Like Terms

Step 3:

x = 180° - 130°      Subtract 130° on both sides

1. A mass of 630g is hung on a spring. Using Force = mass x gravity, what is the force of the mass, acting on the spring?

Answers

Answer:

The answer is 6.3

Explanation:

[tex]f \: = \: m(kg) \times g( \frac{n}{kg} )[/tex]

[tex]f \: = \: 630 \times {10}^{ - 3} \times 10 = 6.3[/tex]

The normal force acting on a body is the weight by gravitational pull of earth. The force acting on the hanging mass of 630 g is 6.17 N.

What is force?

Force is an external agent acting on a body to deform it or to change it from the state of rest or motion. Force is a vector quantity having both magnitude and direction.

A  normal force acting on a body is due to its weight by gravitational pull of earth. The force of gravitation is a kind of force by which an object attracts other objects into its centre of mass. The strength of force depends on the mass of the object.

The weight of an object in earth is the product of its mass and gravity. The acceleration due to gravity on earth is 9.8 m/s². Therefore, the force by weight of the hanging mass of 630 g or 0.630 Kg is :

0.63 × 9.8 m/s² = 6.17 N.

A motorbike is traveling to the left with a speed of 27.0 m s 27.0 s m ​ 27, point, 0, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction when the rider slams on the brakes. The bike skids 41.5 m 41.5m41, point, 5, start text, m, end text with constant acceleration before it comes to a stop. What was the acceleration of the motorbike as it came to a stop?

Answers

Answer:

The acceleration of the motorbike as it came to a stop was -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Explanation:

From the question,

A motorbike is traveling to the left with a speed of 27.0 m/s.

This is the initial speed, that is, initial speed = 27.0 m/s

Also, from the question,

The rider slams on the brakes and the bike skids 41.5 m, that is, the bike covers a distance of 41.5 m after the rider slams on the brakes.

Distance = 41.5 m

To determine the acceleration of the motorbike as it came to a stop,

Since, the bike came to a stop, then, the final speed is 0 m/s

From one of the equations of motion for linear motion

v² = u² + 2as

Where v is the final speed (velocity)

u is the initial speed (velocity)

a is the acceleration

and s is the distance

From the question

v = 0 m/s

u = 27.0 m/s

s = 41.5 m

Putting these into the equation

v² = u² + 2as

0² = 27.0² + (2×a×41.5)

0 = 729.0 + 83a

83a = -729.0

a = -729.0 / 83

a = -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Answer:

8.8 m/s^2

Suppose the airplane in the preceding problem fires a projectile horizontally in its direction of motion at a speed of 300 m/s relative to the plane. (a) How far in front of the release point does the projectile hit the ground? (b) What is its speed when it hits the ground?

Answers

Answer:

a) s = 5619.2 m

b) v = 456.5 m/s

Note: The preceding question is given below:

An airplane flying horizontally with a speed of 500 km/h at a height of 800 m drops a crate of supplies (see the following figure). If the parachute fails to open, how far in front of the  release point does the crate hit the ground?

Explanation:

From the preceding question;

height, h = 800 m,

speed of plane = 500 km/h = 500000 m / 3600 s = 139 m/s

Speed of projectile = 139 m/s + 300 m/s = 439 m/s

a) using h = ut + 1/2 * gt² = 1/2 gt² (sice u = 0)

t = √(2h/g) where g = 9.8 m/s²

t = √(2 * 800/9.8)

t = 12. 8 s

horizontal distance, s = horizontal velocity * time

s = 439 * 12.8

s = 5619.2 m

b) Final vertical velocity v₂ = u - gt

v₂ = 0 - 9.8 * 12.8 = 125.4 m/s

horizontal velocity, vₓ = 439.0 m/s

resultant velocity, v = √(v₁² + vₓ²)

v = √{(125.4)² + (439.0)²}

v = 456.5 m/s

A marble rolls across a table for 6 meters in 2.3 seconds. What is the

v = 6m/2.3 s

v=2.61 [tex]\frac{m}{s}[/tex]

Answer:

[tex]\boxed {\tt v\approx2.61 \ m/s}[/tex]

Explanation:

Velocity can be found by dividing the displacement by the time.

[tex]v=\frac{d}{t}[/tex]

The displacement is 6 meters and the time is 2.3 seconds.

[tex]d= 6 \ m\\t= 2.3 \ s[/tex]

Substitute the values into the formula.

[tex]v=\frac{6 \ m}{2.3 \ s}[/tex]

Divide.

[tex]v=2.60869565 \ m/s[/tex]

Let's round to the nearest hundredth. The 8 in the thousandth place tells us to round the 0 to a 1.

[tex]v\approx2.61 \ m/s[/tex]

The velocity of the marble is about 2.61 meters per second.

A battery provides a potential difference of 14V. What size current will flow through a 10 ohm resistor in this circuit?

Answers

Answer:

I = 1.4 [amp]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.

Therefore:

V = I*R

where:

V = voltage = 14[V]

I = current [amp]

R = resistance = 10 [ohm]

I = 14/10

I = 1.4 [amp]

Davien and Jackson are headed to a beach that is 50km from school. At noon, Davien leaves his house that is 10 km closer to the beach than the school is and moves at 40 km/h. Jackson starts from school at 12:30 P.M. And moves at 100 km/h. What time does Davien reach the beach? * Answer Format: Time

Answers

Distance between Davien's school and beach, D = 50 km.

Also, Davian's house is 10 km closer to the beach than the school.

So, distance between Davien's house and beach, d = 40 km.

Speed of Davian, s = 40 km/h.

Now, time taken is given by :

[tex]t =\dfrac{Distance}{Speed}\\\\t=\dfrac{40}{40}=1\ hour[/tex]

Therefore, Davien reach the beach at 1 : 30 P.M .

Hence, this is the required solution.

A loaded Costco shopping cart has a weight of 188 pounds(lb). You have to push the cart with a force of 14 pounds(lb) to keep it moving with a constant velocity of 1.1 m/s. What must be the magnitude (absolute value) of the force of friction on the cart?

Answers

Answer:

Force of friction = 14 pound

Explanation:

Magnitude = Force / Weight

Magnitude = 14 / 188

Magnitude = 0.074

So,

Force of friction = 14 pound

Force of friction is same as forcee

Frictional force along the direction of motion = 14 pounds

Frictional force is  the resistance force towards relative motion. Frictional Force is a force the equation for which is given by the equation

[tex]f = \dfrac{\mu}{N} \\\mu = Coefficient \; of \; Friction \\\\N = Normal \; Reaction[/tex]

Weight of the  Castco shopping  cart = 188 Pounds (lb)

Force required to push the cart = 14 Pounds

Uniform velocity of shopping cart = 1.1 m/s

Acceleration in the direction of motion of cart = 0 m/s

So we can say that the forces in direction of motion must be balanced

So the  magnitude (absolute value) of the frictional force along the direction of motion

= 14 pounds
