Answer:
A. the words "work" and "energy" are interchangeable.
Explanation:
Work and kinetic energy are interchangeable, so they are the same, ie. they have the same units. Your work can give kinetic energy to a body and a body with kinetic energy can produce work
Answer:
160 watts.
Explanation:
Remark
Power = Work / Time
Work = F * d
Note: Since he is running up stairs he is doing work against gravity.
Givens
- m = 50000 g kg / 1000 grms
- m = 50000 / 1000 = 50 kg
- h = 4 m
- time = 12.5 seconds
- g = 10 m/s^2
Formula
- P = W * d/t
- W = m*g *d / t
Solution
- P = 50kg * 10 m/s^2 * 4 m / 12.5
- <em><u>P = 160 watts. </u></em>

Horn
Explanation:
Glacial horn is a product of glacier erosion which is usually formed when a mountain glacier erodes the sides of a peak and it leaves behind a pointed arching structure.
Glacier erosion occurs mainly by plucking and abrasion. Plucking occurs when glacier carriers sediments along its path.
Glacier abrasion occurs by the scouring action of a moving glacier. This process produces glacial horns.
A delta, sandspit and sandbars forms through river deposition.
