Answer:

D.Acceleration

Explanation:

The acceleration of an object is defined as:

$a=\frac{v_f -v_i}{\Delta t}$

where

vf is the final velocity of the object

vi is the initial velocity of the object

$\Delta t$ is the time taken for the change in velocity to occur

Therefore, from the formula, we see that if we divide (vf - vi) by △t, we get the acceleration.

Which phenomenon generates electric current?

grigory [225]

The one that does that is the photoelectric effect. This allows the sun to hit the surface and produces enough energy for electrons to be knocked off the atom and allows a current to move.

If the distance d (in meters) traveled by an object in time t (in seconds) is given by the formula d=a+bt2, the si units of a an

ss7ja [257]

Distance , d = a+b $t^2$

The unit of d is in meter and t is in seconds.

So the unit of a a must be meter.

Now we have unit of b $t^2$ is meter.

So unit of b* $second^2$ = meter

Unit of b = meter/ $second^2$

So unit of a = m and unit of b = m/ $s^2$ .
