Power is the rate in which work is being done
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).
Explanation:
Acceleration can be calculated by dividing the change in velocity (measured in metres per second) by the time taken for the change (in seconds). The units of acceleration are m/s/s or m/s 2.
Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule

The orbiting spacecraft are put in the atmosphere to gain information about the weather conditions, for satellite communications, for measuring changes in the atmosphere. These crafts are put in the outer atmosphere, where the atmosphere is very thin and the craft can stay its specified orbit.
