Galileo . did not believe friction existed

believed that friction stopped objects in motion

believed that friction kept objects in motion

assumed that in a frictionless environment objects would never move

friction help to slow motion in other word it oppose motion, but in a frictionless environment object would move with difficult stopping point.

C believed that friction kept objects in motion

Explanation: Galileo wold say that due to inertia, the ball would keep moving forever, if it were not slowed to a stop by friction.

Hope it helps!

answer; the correct answer is technician a; ///100%good luck

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.
