100 J of work was done to lift a 10-N rock and set it at Position A near the edge of a cliff. 1. If the 100 Joules of work lifted the rock to the top of the cliff, how much potential energy did the rock gain?

2. At point C, the rock’s potential energy will be _.

3. The rock’s kinetic energy at point A is _.

4. At point B, some of the rock’s potential energy will be changed to _ energy.

5. What is the mass of the rock?

6. What is the rock’s velocity just before it hits the ground?

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

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.
