Which of the following is incorrect statement?

Options

A. energy is essential for life processes
B. organisms grow with time
C. movement of molecules does not take place among cells
D. organisms must repair and maintain their body

Answer

A

Explanation

Given `V_(A)` due to `+Q` is V, so `V_(B)=4V`
By energy conservation
`1/2 m u^(2)+qV=4qV`
`rArr u=sqrt((6qV)/m)`
