The acceleration of an object would increase if there was an increase in the a) mass of the object. b) force on the object. c) inertia of the object. d) friction on the object.

B) force on the object.

Explanation:

From Newton's second law of motion, we understand that the acceleration of an object depends on two factors: The mass of the object and the net force acting on the object.

F = m a

For an object, mass remains constant. So, only by altering the net amount of force, the acceleration can be changed.

a ∝ F

Thus, when the net force would be increased, the acceleration of the object would increase.

the average speed is 24.57 km/hr

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.
