It is impossible to destroy a. motion b. momentum c. energy d. velocity

Energy

Explanation:

We have to fill in the correct option in blank space.

A.Motion: Motion can be destroyed if a person will be stop.

Therefore, it is false.

B.Momentum: Momentum =

When the velocity is zero then, the momentum will be destroy.

Hence, it is possible to destroy the momentum.

C.Energy: Energy cannot be created or destroyed it changes from one form to other form.

Hence, it is impossible to destroy the energy.

D.Velocity:velocity=

When displacement =0 then , the velocity will be zero.

Hence, it is possible to destroy the velocity.

Energy

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
