The answer would be....
Explored the deepest known ocean trench.
Answer:
The correct answer is the spring constant (k)
Explanation:
- Elastic potential energy: Epe = ½ * k * Δx²
k = spring constant
Δx = displacement
- Gravitational ptential energy: Ep = m*g*h
g = (acceleration due to gravity)
m = mass
h = relative height of an object to some reference point
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
