• Newton
• Watts
• All of above
• #### 7.  What will be the formula if we are finding the TIME using the formula of power?

• Time = work donepowerTime\ =\ \frac{work\ done}{power}Time = powerwork doneâ€‹
• Time = powerwork doneTime\ =\ \frac{power}{work\ done}Time = work donepowerâ€‹
• Time = work x powerTime\ =\ work\ x\ powerTime = work x power
• All of above
