IF there is no air resistance, then he could drop a feather, a piece
of Kleenex, a school bus, and a battleship. If he dropped them all
at the same time from the same height, they would all hit the ground
at the same time.
Answer:
Inner planets are small because the heat of the Sun baked off the hydrogen. The outer planets are large because they were colder and did not get the hydrogen baked off. Among the outer planets, they get smaller as you get further out because they formed nearer the edge of the cloud that supplied the material. There was just less to build from.
Answer:
Explanation:
Intake heat, QH = 100 J
output heat, Qc = 20 J
Work, W = 80 J
TH = 100°C = 373 K
Tc = 10°C = 283 K
TH/ Tc = 373 / 283 = 1.318
QH/Qc = 100 / 20 = 5
for a heat engine, those ratios should be same. so temperature is not correct.
Answer:
Forces observed by both is same as both
The frames are non-acceleration
Explanation:
Zweistein = Einstein
=
as tend to zero (0)
< as some quantity is subtracted from the force.
