option D is correct as Average acceleration=Final velocity - Initial velocity/Change in time

Ans 5:

Sriyansh from Surabhi , Hosapete
Class : Class 9
The correct answer is 'd'. M/s^2 or metre per second square. That is because the formula for acceleration is change in velocity /time. The SI unit of velocity is m/s (as it is displacement /time) and the SI unit of time is second. So the SI unit of acceleration is m/s/s which can also be written as m/s^2

Subject :NSO    Class : Class 5

Anil and Brij are hammering a nail into two pieces of wood to join them. Sunita covered her ears, because she said that hammering is noisy. She told them that they are wasting energy because most of the energy they used in hammering is getting lost. Anil disagreed with what Sunita said. Brij explained that some of the energy is converted to sound and heat, but not lost. Anil then added that energy can never be lost or destroyed.
Who among Anil, Brij and Sunita is/are right?

ABrij only
BAnil only
CSunita only
DAnil and Brij only
