5 0

Answer:

The amount of work done in order to lift the box is 150\ Joule

Explanation:

Given the weight of each box is 100N

And the man lifts boxes at a height of 1.5m

We need to find the amount of work done.

The amount of work done is the product of applied force F that causes the displacement d.

In our problem force is 100N and displacement is  1.5m.

Now, work done

=force\times displacement\\=100\times1.5\\=150\ Joule

So, the amount of work done in order to lift the box is 150\ Joule

What is the term that describes waves that require a medium through which to travel?
gladu [14]

Answer:

Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy. One example of a mechanical wave is sound.

Two ice skaters stand together as illustrated in the attached figure. They "push off" and travel directly away from each other,
Tema [17]
By definition, the momentum is given by:
 p = m * v
 Where,
 m = mass
 v = speed.
 On the other hand,
 F = m * a
 Where,
 m = mass
 a = acceleration:
 For the boy we have:
 p1 = m * v
 p1 = (F / a) * v
 p1 = ((710) / (9.81)) * (0.50)
 p1 = 36.19 Kg * (m / s)
 For the girl we have:
 p2 = m * v
 p2 = (F / a) * v
 p2 = ((480) / (9.81)) * (v)
 p2 = 48.93 * v Kg * (m / s)
 Then, we have:
 p1 + p2 = 0
 36.19 + 48.93 * v = 0
 Clearing v:
 v = - (36.19) / (48.93)
 v = -0.74 m / s (negative because the velocity is in the opposite direction of the boy's)
 Answer:
 the girl's velocity in m / s after they push off is -0.74 m / s
