Answers

Answer:

The wheel and axle is a type of simple machine used to make tasks easier in terms of manipulating force by applying the concept of mechanical advantage.Due to the size difference in the radius of the wheel and axle, this means that the distance the two parts rotate through in the same amount of time is different.

You and your friends are going on a picnic in a very small car. On your way, the car breaks down and you try to push it to get it to move but in vain. You ask your friends to help you and the car starts moving and revs up. How are you and your friends applying Newton's second law of motion here? What if the car you were traveling in was a large SUV?

Answers

Answer:

The pushing of the car by you and your friends is the applied force and when the car moves, it means that the velocity has changed thus causing the movement or acceleration.

Explanation:

Newton's work on forces regarding motion can never be neglected by scientists. Sir Isaac Newton when he was alive, among several of his works he proposed the three laws guiding the forces of motion. In this question we are only going to be treating only one out of the three Newton's Law of motion and that is the second Law Of Newton's laws of motion.

The second Law Of Newton's laws of motion states that the acceleration of an object is directly proportional to the applied force and inversely proportional to the object's mass.

(1). Now, to the question: " How are you and your friends applying Newton's second law of motion here? "

The pushing of the car by you and your friends is the applied force and when the car moves, it means that the velocity has changed thus causing the movement or acceleration.

According to the law, the more the Force, the more the acceleration.

(2). For the second part of the question, " What if the car you were traveling in was a large SUV?"

From the law stated above we see that the acceleration is inversely proportional to the mass, thus if the car is a large SUV, It means that more force is needed to change the car's velocity.

Answer:

When a friend joins you in pushing the small car, the net force on it increases. Therefore, it starts to move. The mass of a SUV is much greater than that of a small car. You would thus need the help of more friends to help push it.

Which characteristic is related to kinetic energy but not potential energy?
A. An object's shape
B. An object's mass
C. An object's speed
D. An object's height

Answers

Answer:

c

Explanation:

An object's speed is the characteristic which is related to kinetic energy but not the potential energy. Thus, the correct option is C.

What is Kinetic energy?

The kinetic energy of an object is the energy which it possesses due to the motion of the object. Kinetic energy is defined as the work which is needed to accelerate an object of a given mass from rest position to its stated velocity. Having gained this amount of energy during the acceleration of the object, the object maintains this kinetic energy unless its speed changes or it experiences acceleration.

Kinetic energy is directly proportional to the mass of the object and to the square of the velocity of the object, the expression is:

K.E. = 1/2 m × v²

where, KE = Kinetic energy,

m = mass of the object,

v = velocity of the object.

Therefore, the correct option is C.

An object on another planet with g = 25 m/s^2 hits the ground from rest in 4 seconds. How far did it fall?

Choices:
•200.0m
•100.0m
•1000.0m
•25.0m

Answers

Using the kinematics equations Vf=Vi+ (a)(t) and d=Vi(t)+1/2(a)(t)^2
and given:

d=?
Vi= 0 m/s
Vf=?
g= 25m/s^2 (so a= 25m/s^2)
t= 4sec

you first have to use Vf=Vi+ (a)(t) to solve for Vf:


Vf= (0m/s) + (25m/s^2)(4 sec)
Vf= 100m/s

Now using d=Vi(t)+1/2(a)(t)^2

d= 0m/s +1/2(25m/s^2)(4)^2

Which gives us d= 200.0 meters

Answers

Answer:

490N

Explanation:

Given that,

Mass of a skydiver, m = 50 kg

Buoyant force = 20 N

When the skydiver reaches the terminal velocity, net force on her is equal to 0. So, air drag is equal to the weight of the skydiver.

D = mg

Putting all the values,

D = 50 × 9.8

D = 490 N

So, the force of air resistance is 490 N.

Complete Question

An astronaut stands by the rim of a crater on the moon, where the acceleration of gravity is 1.62 m/s2. To determine the depth of the crater, she drops a rock and measures the time it takes for it

to hit the bottom. If the time is 6.3 s, what is the depth of the crater?

Answer:

The depth is 32 m

Explanation:

From the question we are told that

  The  time is  t =  6.3 s

  The acceleration due to gravity is  [tex]g =  1.62 \  m/s^2[/tex]

 

Generally from kinematic equation

    [tex]s = ut + \frac{1}{2}  - at^2[/tex]

Here the u is the initial  velocity and the value is  0 m/s

      [tex]s = 0 + \frac{1}{2}  - (1.62) * (6.3)^2[/tex]

        [tex]s = 32 \ m [/tex]

Answers

Light, heat, radio, and similar types of energy are carried by a variety of waves in the ELECTROMAGNETIC SPECTRUM. Some energy waves need a medium, such as water or air, through which to travel. The medium moves back and forth as waves carry energy through it, but it does not actually travel along with the wave.

True, energy can in move in waves because waves transfers energy during their propagations.

A wave is a disturbance that transfers energy from one point to another, along its path of propagation.

A wave can be mechanical or electromagnetic.

A mechanical type of wave requires material medium for its propagation.

Examples;

sound wavewater wave

An electromagnetic wave does not require material medium for its propagation.

Examples;

A force of 500 N acts for a time interval of 0.001 second on an object of mass 0.20 kg that was initially at rest. Calculate the final velocity of the object after the force acts

Answers

Answer:

100

Explanation:

The final velocity of the object after the force acts is 2.5 meters per second.

To calculate the final velocity of the object after the force acts, we can use Newton's second law of motion, which states that:

Force = Mass × Acceleration

We need to find the acceleration of the object first. Since the object was initially at rest, its initial velocity (u) is 0 m/s.

The force acting on the object is 500 N, and the mass of the object is 0.20 kg. We can rearrange the equation to find the acceleration (a):

Acceleration (a) = Force / Mass

a = 500 N / 0.20 kg

a = 2500 m/s²

Now, we can use the kinematic equation to find the final velocity (v) of the object:

Final velocity (v) = Initial velocity (u) + (Acceleration × Time)

The initial velocity (u) is 0 m/s (since the object was initially at rest), and the time interval (t) is 0.001 second.

Final velocity (v) = 0 m/s + (2500 m/s² × 0.001 s)

v = 0 m/s + 2.5 m/s

v = 2.5 m/s

Hence, the final velocity of the object after the force acts is 2.5 meters per second.
