Answer:
<h3>Power = Work Done/time</h3>
=> Power = 60×10×10/60
=> Power = 6000/60
=> Power = 100 Watt
Hence the power output of a pump is 100 Watts.
The answer is option A.
Centripetal force is always directed towards the centre and does not change the speed of the body,but there is a change in the direction.
To solve the problem it is necessary to apply the concepts related to Force of Friction and Tension between the two bodies.
In this way,
The total mass of the cars would be,
Therefore the friction force at 29Km / h would be,
In this way the tension exerts between first car and locomotive is,
Therefore the tension in the coupling between the car and the locomotive is 
Answer:
