Torque on a closed current carrying loop is given by formula
here
N = number of turns = 1
i = current = 4 A
A = area of the loop
B = magnetic field = 0.60 T
= angle between normal of the plane and magnetic field = 90 - 30 = 60 degree
Now we will have
So area of the loop is 0.53 m^2
Answer:
925.04 J/s
Explanation:
T = 80 C = 80 + 273 = 353 K
To = 20 c = 20 + 273 = 293 K
A = 2 m^2
Use the formula for Stefan's law
Energy radiated per second
E = 925.04 J/s
