Answer:

Explanation:

As we know that the energy can neither be created and nor be destroyed but it can transform from one form to another.

In case of light bulb, the electric energy is converted in the form of light energy.

A light bulb is an example of converting electrical energy into light energy.

Answer:

$F=1.98\times 10^{20}\ N$

Explanation:

Given that,

The mass of a Moon, $M_m=7.35\times 10^{22}\ kg$

The mass of the Earth, $M_e=5.98\times 10^{24}\ kg$

The moon's mean orbit distance around the earth is, $r=3.84\times 10^8\ m$

We need to find the gravitational force exerted on the moon by the Earth.

The formula of gravitational force is given by :

$F=G\dfrac{M_mM_e}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{7.35\times 10^{22}\times 5.98\times 10^{24}}{(3.84\times 10^8)^2}\\\\F=1.98\times 10^{20}\ N$

So, the required force is $1.98\times 10^{20}\ N$ .

Klio2033 [76]

Answer:

a) $u=0.05602\ m.s^{-1}$

b) $u'=0.0169\ m.s^{-1}$

Explanation:

Given:

mass of the ball, $m=0.4\ kg$

horizontal velocity of the ball, $u=10\ m.s^{-1}$

mass of the person, $M=71\ kg$

<u>Using the law of conservation of momentum:</u>

$m.v=(M+m).u$

$0.4\times 10=(71+0.4)\times u$

$u=0.05602\ m.s^{-1}$

Given:

rebound velocity of the ball, $v'=7\ m.s^{-1}$

Using conservation of momentum,

$m.v+M.u=m.v'+M.u'$

$0.4\times10+71\times 0=0.4\times 7+71\times u'$

$u'=0.0169\ m.s^{-1}$

What average energy of particles does temperature measures?

sertanlavr [38]

Answer:

Well, temperature is simply an average measure of the kinetic energy for particles of matter. Another way of putting it would be that temperature simply describes the average vibration of particles. Because the motion of all particles is random, they don’t all move at the same speed and in the same direction.
