Answer:
Energy = 0.25 kilowatt-hour
Explanation:
Given the following data;
Power = 25 Watts
Time = 10 hours
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
To find the energy consumed;
Energy = power * time
Substituting into the formula, we have;
Energy = 25 * 10
Energy = 250 Watt-hour
To convert to kilowatt-hour, we would divide by 1000;
Energy = 250/1000
Energy = 0.25 kilowatt-hour
Answer:
potential energy is like compressed - spring like

Explanation:
Explanation:
In the given question, there are two conditions.
Ram traveled 50 m in 30 seconds in a straight road.
Hari covers the same distance in the road; that means 50 m in 45 seconds
The formula for work w=\frac{d}{t}w=td
Ram's work w=\frac{50}{30}=1.66666w=3050=1.66666
Hari's work w=\frac{50}{45}=1.111w=4550=1.111
Ram is slower than Hari and the velocity of Ram is slower than Hari.
Ram has done less work than Hari.
Hence, Hari has done more work and he has more power than Ram.
