3. The Earth's mass is 5.98 x 10^24 kg and its average distance from the sun is 1.495 x 108 km. What is the Earth's period around the sun and it's centripetal acceleration to keep it moving?
How much is the Sun's centripetal force on Earth so it stays in its orbit?

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
