Athletes such as swimmers and bicyclists wear body suits in competition. Formulate a list of pros and cons of such suits.

Answers

Answer 1

There is a drag force that opposes a person's motion while they are moving through a fluid, whether it be air or liquid. Range of motion is constrained by the drag force. Drag force is overcome by the suits. The drawback is overheating.

A bodysuit's main function is to give you support and a seamless tuck-in so you may dress comfortably and easily. Bodysuits can be skin-tight or loose, and because of the tension they create from the shoulders to the crotch, they can embrace your curves and serve as the ideal foundation for whichever bottom you choose.

They can be warm and tight or very thin - useful for warmth - or even be very light (say, 60g), cooling underwear. They are typically elastic and stretchy. They can serve as both underwear and outerwear, but a pair of trousers, pants, or a skirt must be worn below.

Benefits include being thin, warm or cooling, extremely snug, occasionally shapewear, suitable for layering, and warm without bulk (you can get a big deal from a 60g torso garment). fitting in.

They interfere with using the restroom and can occasionally make it difficult to distinguish their front from back sides. Typically, the longer portion of the crotch, called the tail, is at the back. The bodysuits without arms, however, can also be worn buttoned up.

Answers

The plane's speed at the end of 10.0 seconds is 200 m/s and the distance it has travelled is 1750 meters.

The initial speed of the plane, u = 150 m/s

Acceleration of the plane, a = 5 m/s²

Time, t = 10 sec

We can find the plane's speed at the end of 10. 0 seconds by the formula

a = (v - u)/ t

⇒5 = (v - 150)/ 10

⇒50 = v - 150

⇒v = 150 + 50

⇒v = 200 m/s

A 200-kg crate is pushed horizontally with a force of 720 N. If the coefficient of friction is 0.20, calculate the acceleration of the crate.

Answers

1.54 is the acceleration of the crate. The Second Newton's law states that an object acquires acceleration when an external unbalanced net force is applied to it.

Acceleration is proportional to the net force.

That acceleration is proportional to the net force and inversely proportional to the mass of the object. It can be expressed with the formula: Where, Fn = Net force, m  = mass. The m=200 kg crate is pushed horizontally with a force Fa=700 N. The friction force opposes the motion and a horizontal net force appears causing the acceleration.

Forces in the vertical direction?

The forces in the vertical direction are in balance since the crate does not accelerate in that direction, thus the weight and the normal force are equal: N = W = mg, The friction force can be calculated by using the coefficient of friction μ: μ*n. Calculating the normal force: N = 200 * 9.8 = 1,960 N. The friction force is f=0.2*1960, f=392. The horizontal net force is 308. Finally, the acceleration is computed: m/s^2

Answers

When the amplitude of a body undergoing simple harmonic motion is doubled then the maximum speed is doubled.

Equation of shm is

Differentiate it with t

v(t) = wA * sin(wt + f)

Then max speed Vmax is wA

So by above relation if we double the amplitude then velocity will be doubled.

If the force acting on the oscillating body is always in the direction opposite to the displacement of the body from the equilibrium or the mean position and its magnitude is proportional to the magnitude of displacement, the body is said to be executing SHM.

If the displacement vs. time curve of the oscillating body is sinusoidal in nature, the body is said to be executing SHM. This is another definition of SHM.

If an object was traveling horizontally off a cliff at 6 m/s for 3 seconds, how long did it take to
hit the ground?

Answers

The time taken by the object to hit the ground is 1.8 seconds.

What do you mean by gravitational force?

The attraction that draws two objects together is known as gravitational force, sometimes referred to as gravity. Every mass-containing object pulls on nearby things gravitationally in a sizable way.

The time it takes for an object to hit the ground after being dropped off a cliff can be calculated using the formula:

t = √(2*d/g)

where t is the time, d is the distance fallen, and g is the acceleration due to gravity.

In this case, we don't know the distance fell, but we can use the horizontal velocity and time of travel to find it:

d = v * t

where v is the velocity (6 m/s), and t is time (3 seconds)

d = 6 * 3 = 18 m

Now we can use the distance fallen to calculate the time it takes to hit the ground:

t = √(2*d/g)

g is approximately 9.8 m/s^2

t = √(2*18/9.8) = √ (3.6) = 1.8 seconds

So, it takes 1.8 seconds for the object to hit the ground after traveling horizontally off a cliff at 6 m/s for 3 seconds.

Answers

The magnitude of the torque will increase as the angle between the force and the line of action of the torque approaches 90 degrees.

Torque is a measure of the rotational force acting on an object and is defined as the product of the force and the distance from the axis of rotation to the point where the force is applied. The torque is also proportional to the sine of the angle between the force and the line of action of the torque.

When the angle between the force and the line of action of the torque is 0 degrees, the torque is zero, as the force is acting in the same direction as the line of action of the torque. As the angle increases, the torque increases and reaches its maximum value when the angle is 90 degrees, at this point the sine of the angle is 1, so the torque is at its maximum value.

In practical terms, if you imagine a door knob, when you push or pull the door knob closer to 90 degree angle with the door, it will be harder to open or close the door, than when you push or pull the door knob at a small angle.

Answers

A Shuttle astronaut is sent to repair a defective relay in a 600. 00- kg satellite that is traveling in space. The combined velocity when the astronaut grabs hold of the satellite is 17,004.4 m/s.

The combined velocity of the astronaut and the satellite when the astronaut grabs hold of the satellite is the relative velocity between the two objects. The relative velocity can be calculated using the principle of conservation of momentum. The principle states that the total momentum of an isolated system remains constant if no external forces act on it.

The initial momentum of the satellite is

= (600.00 kg) * (17,000.0 m/s)

= 10,200,000 kg*m/s

The initial momentum of the astronaut and the MMU is

= (400.00 kg) * (17,010.0 m/s)

= 6,804,400 kg*m/s

The final momentum of the combined system is

= (600.00 kg + 400.00 kg) * v,

where v is the final velocity of the combined system.

The conservation of momentum equation:

=> initial momentum = final momentum

= 10,200,000 kgm/s + 6,804,400 kgm/s

= (1000 kg) * v

= v

= (10,200,000 + 6,804,400) / 1000

= v

= 17,004.4 m/s

So, the combined velocity of the astronaut and the satellite when the astronaut grabs hold of the satellite is 17,004.4 m/s.

A car is traveling $$ m/s when the gas pedal is released and the brakes are gradually applied, resulting in an acceleration given by the function $$ m/s^2. What is the distance traveled before the car comes to a stop?

Answers

The distance traveled before the car comes to a stop is 66.66 m. It's important to note that the negative sign on acceleration indicates that the car is slowing down.

Calculation-

To find the distance traveled before the car comes to a stop, we can use the formula for distance traveled under constant acceleration. The formula is:

Distance = initial velocity * time + (1/2) * acceleration * time^2

The car is traveling at an initial velocity of 20 m/s and the acceleration is given by the function -6.0t, where t is the time in seconds.

We can find the time it takes for the car to come to a stop by setting the final velocity to 0 and solving for t.

0 = 20 + (-6.0)t

t = 20/6

t = 3.333 s

Now that we have the time, we can substitute it back into the distance formula along with the initial velocity and acceleration:

Distance = 20 * 3.333 + (1/2) * -6.0 * (3.333)^2

Distance = 66.66 m

The frequency of the red light emitted by a neon sign with a wavelength of 659.9 nm is 4.5×10^14 Hz.

What is the frequency?

The frequency is the number of times a recurring occurrence takes place during a predetermined period. For example, if an event occurs twice in one second, then the frequency is 2 Hz (Hertz).

A recurring event's frequency is the number of times it happens in a predetermined period. For example, a frequency of a wave is the number of wave peaks passing a fixed point in one second.

The frequency is the number of times something occurs in a given period. For example, the frequency of a radio station is the number of times it broadcasts a signal per second.

Given:

Wavelength = 659.9nm

Speed of light = 3×10^8 m/s

Frequency = speed of light / wavelength

Frequency = (3.0 x 10^8 m/s) / (659.9 nm)

Frequency = 4.5 x 10^14 Hz

An electron is projected with an initial speed v0 = 1. 10106m/s into the uniform field between the parallel plates in the figure. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates.


(a)If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field.


(B) suppose that in the figure, the electron is replaced by a proton with the same initial speed. Would the proton hit one of the plates?


(c) what would be the direction of proton's displacement? upward or downward?


(d) compare the paths traveled by the electron and the proton and explain the differences

Answers

The electron feels a force upward as it passes between the charged plates and narrowly avoids striking the top plate. It just misses the to plate by a small amount as it moves higher.

The explanation for the above answer:

The proton will accelerate less and miss the plates since it is more massive. We once more utilise the kinematic equation to determine the vertical displacement when it occurs for the plates.

y=1/2at²=1/2eE/mp(1.25×10-8s)

² \s=2.73×10-6m

As stated in (b), the proton won't collide with one of the plates because, despite the fact that the electric force felt by the proton and the electrons is identical, the electric force produces a smaller acceleration than g, making it plausible to disregard gravity.

At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.0 m/s, and an 83-kg person feels a 545-N force pressing against his back. What is the radius of a chamber

Answers

When the outer wall moves at a speed of 3.0 m/s, and an 83-kg person feels a 545-N force pressing against his back then the radius of a chamber is 8.5 meters.

The radius of the chamber can be calculated using the equation

F = mv²/r, where F is the force felt by the person, m is the mass of the person, v is the velocity of the chamber and r is the radius of the chamber. In this case, F is 545 N, m is 83 kg, and v is 3.0 m/s.

Plugging in these values, we get

r= mv²/F

r= 83×3²/545

r = 8.5 m.

Therefore, the radius of the chamber is 8.5 m.
