<h3>Answer:</h3>

100 Joules

<h3>Explanation:</h3>

The question is testing on how to calculate work done;

We are given;

  • Mass of an object is 5 kg
  • Distance moved is 2 m

We are required to calculate the amount of work done.

How do we calculate work done?

  • Work done is the product of force and distance.
  • Therefore without distance covered no work is done.
  • Work done = Force × distance
  • Additionally, it is measured in joules or Nm

In this case;

Force = mass × 10 N/kg

         = 5 kg × 10 N/kg

         = 50 N

Therefore;

work done = 50 N × 2 m

                  = 100 Joules

Thus, the work done in lifting the object is 100 Joules

Nikitich [7]

Answer:

<em>BCEG,ADF</em>

Explanation:

Between 2 waves, if path difference is mλ, m is an integer and they interfere constructively.

Between 2 waves, if path difference is (m+1/2)λ, m is an integer and they interfere destructively.

Write an argument of any one
vampirchik [111]
<h3>I do think parallel universes exist. There are now some scientific theories that support the idea of parallel universes beyond our own. However, the multiverse theory remains one of the most controversial theories in science.Our universe is unimaginably big. Hundreds of billions, if not trillions, of galaxies(opens in new tab) spin through space, each containing billions or trillions of stars(opens in new tab). Some researchers studying models of the universe speculate that the universe's diameter could be 7 billion light-years(opens in new tab) across. Others think it could be infinite.

u might never know. It might or might not exist in conclusion. </h3>

In order to do work, the force vector must be
gregori [183]

As we know that total work done by a force is given by

W = F.d

W = Fdcos\theta

so it is product of force and displacement along same direction

as we can write it as

W = (Fcos\theta)(d)

so it must be the product of force and displacement in same directions so correct answer must be

<u>B. in the same direction as the displacement vector and the motion.</u>

How does the density of a water in a tank and the density of a water in a glass can be same density since water's density is 1
Vinvika [58]
Just because there is more mass in a certain substance doesn’t mean it’s density will change. In this case, water, will not change density simply because there is more of it. I.e the ocean. The bottom of the ocean may have more pressure to it because of the weight of the water above it but if you were to take a cup of it and take it to the surface it wouldn’t sink.
