Explanation:
define speed because change in motion is known as it is also the definition of speed and if there is change in motion then there will be increase of speed or decrease of speed so the answer is speed
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

Explanation:
An electrical shock is received when electrical current passes through the body. ... Whenever two wires are at different voltages, current will pass between them if they are connected. Your body can connect the wires if you touch both of them at the same time. Current will pass through your body.
The force he must exert is 300 N
