What is the weight (in pounds) of a 7.0 kilogram bowling ball on earths surface

A bowling ball of 7.0 kg will be weighed around 15.54 lbs (pounds) at the surface of the Earth.

Explanation:

The weight of the bowling ball as given in the question,

Since we know that the force of gravity acting on an object at the surface of the Earth is 2.22 lb i.e. the object will be weighed as 2.22 lb at the surface of the Earth. Similarly, here in this case;

The weight of the bowling ball,

Hence, the bowling ball will be weighed as 15.54 lbs at the surface of the Earth.

answer; ///i believe that the correct answer is (carbon); 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.
