If your mass is 20kg, and you stand on the scale (witch is your force), and the acceleration due to gravity is10m/s^2, what does the scale says your weight is?

Explanation:

Your mass is 20 kg.

The acceleration of gravity is approximately 10 m/s².

Your weight is 200 N.

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.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
