Actually it's 
and it says that the energy of an object (E) is equal to the mass (m) of the object multiplied with the squared speed of light (
). This theory says that mass can be turned into energy and energy can be turned into mass. This is one of Einstein's theory of relativity.
Answer:
l= 3.002 cm
Explanation:
Given that
n= 70 turns
B= 1.2 T
θ= 15°
I= 1.5 A
τ = 0.0294 N⋅m
Lets take length of sides is l.
We know that
τ = n I A B sin θ
Area of square ,A= l²
Now by putting the value
τ = n I A B sin θ
0.0294 = 70 x 1.5 x l² x 1.2 x sin 15°
l² = 0.000901 m²
l² = 9.01 cm²
l= 3.002 cm
