Answer:
If you are asking the definition here is your answer:--
Explanation:
<u><em>Electrons</em></u> are negatively charged particles that revolve around the nucleus of an atom. In QFT(Quantum field theory) Electrons are vibration of space in the positive energy field.
<u><em>Protons </em></u> are positively charged particles found in the nucleus of an atom held by the strong nuclear force. In QFT(Quantum field theory) protons are also different type of vibration in space in the direction of positive energy field.
Because the gravitational field strength on the moon (1.6N/kg)is smaller than the gravitational field strength on the earth (9.8N/kg). Weight= mass×gravitational field strength. Your mass is the same but as g is smaller, your weight decreases. weight is the gravitational force, the downwards force towards the centre of the planet, and as it will be smaller on the moon, the force of attraction between the moon and you is smalller so when you jumb you will reach a higher point above the ground than when you jumb on the earth. Basically the moon 'pulls' you less than the earth.
If we have to figure air resistance into it, then we don't have enough information to find an answer.
If the air around it is going to have an effect on how it falls, then it'll depend on the thickness of the book, the shape of the book, whether it's a hard-cover or soft-cover, how far the covers stick out past the pages, how smooth or rough the covers are, how bumpy the binding it. and what position you hold it in before you let it go.
(THAT's why we always ignore air resistance, especially when the question is actually about gravity anyway.)
answer:
a.fossils of the same plants and animals are found on widely spread continents
explanation:
four fossil examples include; the mesosaurus, cynognathus, lystrosaurus, and glossopteris.
good luck :)
i hope this helps
have a nice day !!
Kinetic energy = 0.5 x m x v²
Kinetic energy = 0.5 x 3.8 x 2.2²
Kinetic energy = 9.196 J
