Answer:
a) 1.51Vm/s
b)Id=0.134A
Explanation:
(a) The time rate of change of electric flux between the plates can be computed by using:
where Ic is the current of the capacitor, e0 is the dielectric permittivity of vacuum and A is the area of the capacitor.
(b) The displacement current coincides with capacitor current:
Id = 0.134A
hope this helps!!
Answer:
9 m/s
Explanation:
Wyatt maintains the maximum speed for the rest of the race. This motion begins when his displacement is 40 m and the time is 7 s. At time 12 s, his displacement is 85 m. Because this motion is constant-velocity, the maximum speed is given by
The acceleration is 2 mph/min
Explanation:
The acceleration of an object is the rate of change of velocity. It is defined as follows:
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to v
For the car in this problem, we have (taking North as positive direction):
u = 25 mph
v = 35 mph
t = 5 min
Substituting into the equation, we find the acceleration:
