You can’t just do this tm u have to do it now
Answer:
Explanation:
maximum energy of capacitor
E = 1/2 C V ²
C is capacitance of capacitor and V is potential difference
given V = 88 V
E = 2002 x 10⁻⁶ J
Putting the values
2002 x 10⁻⁶ = 1/2 x C x 88²
C = .517 x 10⁻⁶ F .
In the second case
Energy E = 125 x 10⁻⁶ J .
C = .517 x 10⁻⁶
V = ?
E = 1/2 C V ²
125 x 10⁻⁶ = 1/2 x .517 x 10⁻⁶ x V²
V² = 483.55
V = 21.98 V .
Answer:
Explanation:
Given
Weight of strut 
Weight of sign Board 
In this question angle which cable makes with horizontal is not given so
assuming 
From Diagram
Moment about hinge point
in x direction is zero
in Y direction is zero therefore
Explanation:
EE = ½ kx²
EE = ½ (0.55 N/m) (0.15 m)²
EE = 0.62 J
Yes because they believe they were formed from magma solidifying.
