Answer:
"The capacity of a system to perform work of any type."
Explanation:
The best statement to describe Energy is:
"The capacity of a system to perform work of any type."
Answer:
100 N is the answer of the question
Answer:
(a) The current should be in opposite direction
(b) The current needed is 39.8 A
Explanation:
Part (a)
Based, on right hand rule, the current should be in opposite direction
Part (b)
given;
strength of magnetic field, B = 370 µT
distance between the two parallel wires, d = 8.6 cm

At the center, the magnetic field strength is twice

R = d/2 = 8.6/2 = 4.3 cm = 0.043 m

Therefore, current needed is 39.8 A
Light will travel more slowly in a material with a higher index of refraction
