प्रश्न
How much electrical energy in joules does a 100 watt lamp consume : in 1 minute?
Advertisements
उत्तर
Time (t) = 60 s
Now, we can calculate the electrical energy consumed as,
Energy consumed = Power × Time
So,
Energy consumed = 100 × 60 J
= 6000 J
So, the energy consumed is 6000 J.

An automobile engine propels a 1000 kg car (A) along a levelled road at a speed of 36 km h–1. Find the power if the opposing frictional force is 100 N. Now, suppose after travelling a distance of 200 m, this car collides with another stationary car (B) of the same mass and comes to rest. Let its engine also stop at the same time. Now the car (B) starts moving on the same level road without getting its engine started. Find the speed of the car (B) just after the collision.
