AP EAMCET · PHYSICS · Work Power Energy
An engine develops of power. How much time will it take to lift a mass of to a height of
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
In physics, power is the amount of energy transferred or converted per unit time. Power, P=m×g×ht ⇒t=m×g×hP ⇒t=200×10×4020000 ⇒t=8000020000 ⇒t=4 s
