Answer:

Yes, the given statement is correct.

Explanation:

In the phenomenon photoelectric effect, when photon(energy packet of light) falls on a conductor or semiconductor emits electron and when that electron passes through a closed circuit electric current flow though it. This photoelectric effect have vast application now a days such as:- solar cell, photo cell,solar pump.

Answer:

$+1 m/s^2$

Explanation:

Acceleration is given by

$a=\frac{\Delta v}{\Delta t}$

where

$\Delta v$ is the change in velocity

$\Delta t$ is the time interval in which the change in velocity occurs

To find the acceleration at 1 second, we can take the data at t = 1 s and t = 2. We find:

$\Delta t = -3 -(-4) = 1 s$

$\Delta v = 2 - (1) = +1 m/s$

So, the acceleration is

$a=\frac{+1}{1}=+1 m/s^2$
