Answer:
Explanation:
The capacitance of a parallel plate capacitor is given by:
(1)
where
is the vacuum permittivity
A is the area of the plates
d is the separation between the plates
The charge stored on the capacitor is given by
(2)
where C is the capacitance and V is the voltage across the capacitor.
The displacement current in the capacitor is given by
(3)
where t is the time elapsed
Substituting (1) and (2) into (3), we find an expression for the displacement current:
where we have
Substituting into the equation, we find
Answer:
The answer is below
Explanation:
The main difference between a liquid and a gas is that when a liquid is under pressure, its volume "won't change apparently. The reason is that the distance between the molecules of a liquid is relatively small, and the molecules of a liquid extensively withstand the compressive forces. This is similar to the distance between the molecules of a solid."
Answer:
-50 N
Explanation:
Givens:
V_i = 36 km/h
V_f = 18 km/h
t = 2 s
m = 20 kg
First we have to convert our km/h into m/s:
(36 km*(1000 m/1 km)) / (60 min *(60 s/1 min)) = 10 m/s
(18 km*(1000 m/1 km)) / (60 min *(60 s/1 min)) = 5 m/s
a = (V_f - V_i)/t
a = (5 m/s - 10 m/s) / 2 s
a = -2.5 m/s^2
F = m(a)
F = 20 kg(-2.5 m/s^2)
F = -50 N
It's a negative force meaning its acting on it opposite its current direction of movement.
