Answer:
0.232 mm.
Explanation:
Power, P = 96 W
Voltage, V = 120 V
Length of wire, l = 4.2 m
Let r be the radius of the wire.
Resistivity of nichrome, ρ = 1.5 x 10^-6 ohm metre
P = V^2 / R
R = 120 x 120 / 96 = 150 ohm
r = 1.16 x 10^-4 m
Diameter = 2 x r = 2 x 1.16 x 10^-4 = 2.32 x 10^-4 m = 0.232 mm
Thus, the diameter of the wire is 0.232 mm.
Answer:
I beileve its A because energy is what gives the ability to do work
Explanation:
Answer:
Explanation:
If the family needs 26 kW of power, and knowing that the efficient is 30% the relation between the solar flux and the power would be:
(1)
e is the efficient (in our case 0.3)
Φsolar is the solar flux
S is the effective surface
Solving (1) for S we have:
