The driver had to stop suddenly. The cars shock absorbers are springs.
At one point while the car was braking, one shock absorber had an elastic potential energy of 258J.
The spring constant of the shock absorber is 45,300N/m.
Calculate the extension of the shock absorber

coil wire, increase current, put iron inside the coil

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

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.

less than one you can't create energy
