When the speed is doubled, KE also gets doubled.

When speed is doubled, KE becomes 4 times.

Assertion: At constant temperature, if pressure on the gas is doubled, density is also doubled. Reason: At constant temperature, molecular mass of a gas is directly proportional to the density and inversely proportional to the pressure

Assertion: At constant temperature, if pressure on the gas is doubled, density is also doubled. Reason: At constant temperature, molecular mass of a gas is directly proportional to the density and inversely proportional to the pressure

Assertion: At constant temperature, if pressure on the gas is doubled, density is also doubled. Reason: At constant temperature, molecular mass of a gas is directly proportional to the density and inversely proportional to the pressure

A : To a metal wire of diamete d and length L when the applied voltage is doubled, drift velocity gets doubled. R : For a constant votage when the length is doubled, drift velocity will be halved but drift velocity is independent of diameter .

Two forces P and Q of magnitude 2F and 3F, respectively, are at an angle theta with each other. If the force Q is doubled, then their resultant also gets doubled. Then, the angle theta is

The root mean square speed of the molecules of a diatomic gas is v. When the temperature is doubled, the molecules dissociates into two atoms. The new root mean square speed of the atom is

The root mean square speed fo molecules of nitrogen gas is v at a certain temperature. When the temperature is doubled, the molecules dissociate into individual atoms. The new rms speed of the atom is:

How is the resistance of a wire affected if its (a) length is doubled, (b) radius is doubled ?

IF the current is doubled, the deflection is also doubled in
