Answer:
The magnitude of the force that each wire exerts on the other will increase by a factor of two.
Explanation:
force on parallel current carrying wire, F = BILsinθ
where;
B is the strength of the magnetic field
L is the length of the wire
I is the magnitude of current on the wire
θ is the angle of inclination of the wire
Assuming B, L and θ is constant, then F ∝ I
F = kI

When the amount of current is doubled in one of the wires, lets say the second wire;

Also, if will double the amount of current on the first wire, then
F₁ = 2F₂
Therefore, the magnitude of the force that each wire exerts on the other will increase by a factor of two.
Explanation:
a. The net force is the upward force of the chute minus the weight of the crate.
∑F = F − mg
∑F = 150 N − (11 kg) (9.8 m/s²)
∑F = 42.2 N
b. From Newton's second law, the net force equals the mass times acceleration:
∑F = ma
42.2 N = (11 kg) a
a = 3.84 m/s²
c. Acceleration is the change in velocity over change in time. Assuming the crate is released from rest:
v = at + v₀
v = (3.84 m/s²) (5 s) + (0 m/s)
v = 19.2 m/s
Answer: Heat current through the insulator=196W
Electric power= 196W
Explanation: Given: Kglass = 0.040W/m
Temperature of inside glassTi=175°C
Temperature of outside glass To= 35°C
Area=1.4m^2 , L= 4×10^-2
Heat current(H)= K ×A× (Ti - To)/L
Substituting the values into the equation
H = 0.04 × K × 1.4 ×(175-35)/4×10^-2
H= 196W.
The electric power = Heat current =196W
The electric power is the magnitude of heat current
