Answer:
The acceleration is 0.062 m/s^2.
Explanation:
mass = 12 kg
F = 30 N at 20° right
F' = 45 N at 50° left
Let the acceleration is a.
The net force is
F'' = F' cos 50° - F cos 20°
F'' = 45 x 0.643 - 30 x 0.94 = 28.94 - 28.2 = 0.74 N
According to the Newton's second law
0.74 = 12 x a
a = 0.062 m/s^2
Answer:
13
Explanation:
13.0120481928 it is the distance
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
The seasons basically wouldn't change, because basically only one spot would be facing directly at the sun the whole time, so it would be summer there forever, and the edges that barely get any sun would be in eternal winter.
