1.	When do you apply more power-when you lift a pen or when you lift a book?
Answer» Power = \(\frac{Energy\,Consumed}{Time\,taken}\) A book has more mass than a pen, so when a book is lifted more energy will be consumed than that when the pen is lifted. Since power is directly proportional to energy so more power will be applied in lifting a book.

When do you apply more power-when you lift a pen or when you lift a book?

Answer»

Power = \(\frac{Energy\,Consumed}{Time\,taken}\)

A book has more mass than a pen, so when a book is lifted more energy will be consumed than that when the pen is lifted. Since power is directly proportional to energy so more power will be applied in lifting a book.
