Explanation:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pullson the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
Answer:
5.08m
Explanation:
Charge on an electron=
Number of electrons=2
Mass of electron=
Weight of electron=mg
Where g=Acceleration due to gravity=9.8
Using the formula
Weight of an electron=N
Force between two electrons =Weight of an electron
We know that
Electrostatic force =
Where Charge
r=Distance between two charges
Using the formula
Hence, the distance between two electrons=5.08m
EM waves travel at the same speed in all settings.
however their wavelength will be different as the frequency is different.
we know, v = f x lambda,
v is determined by the medium
Never are fully correct but b would be most right
