Answer:
Power = 7.5 watt
Explanation:
Given data:
Power expend = ?
Force applied = 10 N
Distance cover = 1.5 m
Time = 2 s
Solution:
Power = work/ time
First of all we will calculate work.
Work = Force × distance
Work = 10 N × 1.5 m
Work = 15 N.m
Now we will calculate the power.
Power = 15 N.m / 2s
N.m/s = 1 watt
Power = 7.5 watt

Answer:
Tyre
In cold weather, you might have regularly kept a check on the pressure of the tyres of your car. Driving increases the temperature of the tyres, and, therefore, the air inside the tyre warms and expands. When you measure the pressure of the tyres at the time when you have just driven the car, it will be high. However, in cold weather, the pressure of the tyres will be low. So, it is recommended that you should always measure the pressure of the tyres.
