Will give major ! an object's mass is a measure of how much matter makes it up. an object's weight is a measure of the gravitational force that acts on it. an object's mass is always its weight.
a. doubleb. equal toc. proportional tod. half of

I know that A, B, and D are wrong, so C must be the answer. The best way to distinguish Mass and Weight is that Mass always stays the same. If your mass is 100kg on Earth, your mass will be 100kg on the Moon. Conversely, if your weight is 100kg on Earth, your weight on the Moon would be 16.5 kg. Does that help at all?

They are all full and don't need any more electrons in there outer shell.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
