Why is avagardo number constant?
Why do think a 10 kg iron ball weighs 10kg where ever its place of origin be. like wise avagardo no is also constant.
An astronaut's helmet has a mass of 1.2 kg on earth and weighs 2.6 pounds it weighs 0.4 pounds on the moon and has a mass of how many kilograms?
1.2 kg. Mass is constant regardless of gravitational pull (loction).
What is the mass of a cat that weighs 37.2 N?
On Earth, the gravitational constant, represented by 'g' is 10. To calculate the force in Newtons acting on an object, multiply the mass in kg by 'g'. That would mean said cat weighs 3.72 kg.
How many btu's to raise 1 liter of water 1 degree?
There are 3.966 BTU in a kilocalorie (kcal), and 1 kcal raises 1 kg of water 1 degree C, but to work through it:1 BTU raises 1 pound of water 1 degree F, and 1 kg = 2.20 pounds, therefore:2.20 BTU raises 1 kg of water 1 degree F, and 1 litre of water weighs 1 kg (basically), therefore:2.20 BTU raises 1 litre of water 1 degree F, and a 1 degree change in F equals 5/9 degree C, therefore:2.20 BTU raises 1 litre of water 5/9 degree C, therefore:3.96 BTU raises 1 litre of water 1 degree C.

A person weighs 100 pounds and earth weighs 16.6lb on the moon which variable is the independence variable explain why?
The independent variable is the person's mass, since the mass of an object is constant regardless of gravitational force.
