Answer:
A
Explanation:
take note that v=d/t (velocity is distance over(divided by) time, so in this case it would be 200 (distance) divided by 2 (time)
Answer:
a) 0.723 m²
b) 2000V
Explanation:
Given that
Thickness of the capacitor, d = 0.08*10^-3 m
Dielectric constant of the capacitor, k = 2.5
Dielectric strength of the capacitor, E = 50*10^6
Capacitance of the capacitor, C = 0.2*10^-6
Permittivity of free space, E• = 8.85*10^-12
a)
The area, A is given by the formula
A = (C * d) / (k * E•)
A = (0.2*10^-6 * 0.08*10^-3) / (2.5 * 8.85*10^-12)
A = 1.6*10^-11 / 2.213*10^-11
A = 0.723 m²
b)
Potencial difference, V is given by the formula
V = E * d
V = 1/2 * 50*10^6 * 0.08*10^-3
V = 1/2 * 4000
V = 2000 V
The object is at rest. This is because time is going by and there’s no distance being added
Because, say the diamond was 125 feet on both right and left fields, the center field would be 130 feet long, see what i mean? I hope I helped. :)
