Which one is the best explanation of energy?
vladimir1956 [14]

The energy of a substance is defined as the capacity to do work.The energy may be possessed by the body in various forms.It may be kinetic,potential,magnetic.electric etc.

a- The energy can be transformed from one form to another form.It is called energy conversion.

c-The power defined as the consumption of energy per unit time.

              Mathematically\ power\ P=\frac{E}t} =\frac{W}{t}      

Here E is the energy and W is the work done,t is the time.

d-The S.I unit of energy is Joule[J].

    Hence the correct answer to the question is b. the ability to do work

A cricket player hit a ball of mass 250 g moving with velocity of 6 m/sec. if ball move with a velocity of 9 m/sec in opposite d
PolarNik [594]

Explanation:

Given that,

Mass of a ball, m = 250 g = 0.25 kg

Initial velocity of the ball, u = 6 m/s

Final velocity of the ball, v = -9 m/s

(a) Impulse of the system is given by :

Impulse = change in momentum

J = m(v-u)

J = 0.25(-9-6)

= -3.75 kg-m/s

(b) Impulse = Ft

If t = 0.5 min = 30 s

So,

F=\dfrac{J}{t}\\\\F=\dfrac{-3.75}{30}\\\\F=-0.125\ N

So, impulse of the system is -3.75 kg-m/s and the force is -0.125 N.
