We can use the following equation to solve for the gravitational force:
Fg = force due to gravity (N)
G = Gravitational constant
m1,m2 = masses of the objects (kg)
r = distance between the objects (m)
Plug in the given values into the equation:
Answer:
18.6 Ω
Explanation:
Resistance =
But first we have to find the current.
Current =
Power = 0.37W
Voltage = 2.60V
∴ Current =
= 0.14 ( 3 significant figures)
Now we can find the resistance.
Resistance =
= 18.6 Ω ( 3 significant figures)
Answer:
1.47*10^{-8}s
Explanation:
You first calculate the distance traveled by the electron:
Next, you calculate the relative speed as measure by an observer in the positron, of the electron:
with this relative velocity you calculate the time:
