What is the physical quantity that represents the quantity of matter weight mass time length

mass

Explanation:

We see the definitions for each option.

Weight: Weight is the force with which earth attracts a body towards itself. Weight changes with the value of acceleration due to gravity.

Mass: Mass is defined as the quantity of matter contained in a body. It remains constant anywhere in the universe.

Time: The interval of time that passes on

mass

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

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.
