Answer:
Volume strain is 0.02
Explanation:
Volume strain is defined as the change in volume to the original volume.
It is given that,
Initial volume of the plastic box is 2 m³
It is then submerged below the surface of a liquid and its volume decreases to 1.96 m³
We need to find the volume strain on the box. It is defined as the change in volume divided by the original volume. So,
So, the volume strain on the box is 0.02.
Current electricity is caused by flowing negatively charged particles.
Answer:
Two estimates
Explanation:
There are mainly two estimates used in the calculation of depreciation such as the useful life and the salvage value of an asset. The salvage value is defined as the predicted amount that will be obtained by a company from an asset when it is disposed at the end of the useful life of the particular asset. On the other hand, the useful life commonly refers to the estimation of how long the asset is useful for the company. This is different from the lifespan of the asset.
Horizontal speed = 24.0 m/s
height of the cliff = 51.0 m
For the initial vertical speed will are considering the vertical component. Therefore,
Since the student fires the canonical ball at the maximum height of 51 m, the initial vertical velocity will be zero. This means
let's find how long the ball remained in the air.

Finally, let's find the how far from the base of the building the ball landed(horizontal distance)
