Explanation:
w = E
efficiency = (Woutput /Winput) x 100%= Eo/Ei x100%
= (2021 j / 7.4822 kj) x 100%
= 27.01% == B
The I3 will be 158 A.
<h3>How to find the current through the circuit?</h3>
- The foundation of circuit analysis is Kirchhoff's circuit laws.
- We have the fundamental instrument to begin studying circuits with the use of these principles and the equation for each individual component (resistor, capacitor, and inductor).
- These rules aid in calculating the current flow in various network streams as well as the electrical resistance of a complicated network, or impedance in the case of AC.
To calculate I3 firstly, V4 has to be calculated,
For I3,
Hence, the current through I3 will be 158 A.

Velocity
if you change direction, say turn around, so does your velocity
an increase in velocity is called accelleration
Answer:
Explanation:
As we know that melting point of silver is
T = 961.8 degree C
Latent heat of fusion of silver is given as
L = 111 kJ/kg
specific heat capacity of silver is given as
now we will have
now from above equation
The elastic potential energy of the spring is 0.31 J
Explanation:
The elastic potential energy of a spring is given by
where
k is the spring constant
x is the compression/stretching of the spring
For the spring in this problem, we have:
k = 500 N/m (spring constant)
x = 0.035 m (compression)
Substituting, we find the elastic potential energy:
