In order for an object to have kinetic energy it must have a mass and a ?

almond37 [142]

Answer:

Velocity

Explanation:

The mechanical energy of the body is defined as the sum of the potential energy and kinetic energy.

E = P.E + K.E

The potential energy of a body is due to the height from the surface of the earth.

P.E = mgh

The kinetic energy of the is possessed by the body due to the virtue of its motion,

K.E = ½ mv²

If there is no velocity associated with the body, there is no K.E in the body.

A circuit has a current of 2.4 A. The voltage is increased to 4 times its original value, while the resistance stays the same. H

9966 [12]

Answer:

Resistance will become 4 times the previous value

Explanation:

We have given current in the circuit i = 2.4 A

According to ohm's law current in the circuit is given by $I=\frac{V}{R}$

So $2.4=\frac{V}{R}$ ............eqn 1

Now voltage is increased to 4 times so new voltage = 4 V

And current in the circuit is same as 2.4 A

We have to fond the resistance so that after increasing voltage current will be same

So $2.4=\frac{4V}{R_{unknown}}$ ..........eqn 2

Dividing eqn 1 and 2

$1=\frac{V}{R}\times \frac{R_{unkown}}{4V}$

$R_{unknown}=4R$

So resistance will become 4 times the previous value
