A 0.75 kg mass attached to a vertical Spring stretches the Spring 3.0 m.
a. What is the Spring Constant?

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.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

d) physical means can be used to separate the components of air.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
