The answer is A.
The brain sends signals by chemical reactions that occur in the neurons to the muscle cells.
The muscle cells, after receiving the signals sent by brain, contract and expand necessarily to execute the action, in other words, it performs work.
Hope this helps you! :)
What you’re doing is so easy pay attention more I think
Answer:
E = 3.049 N/C
Explanation:
Induced electric field = e/2 *(pi) *r
Induced electric field = e /(3.14 *19.5) - Eq (1)
e = (pi)r^2*B/t
= 3.14 * (19.5/2*100)^2 * 0.50 T/ 0.1
= 1.867 V
Substituting this value in equation 1, we get –
E = 1.867 V/(3.14 *19.5/100)
E = 3.049 N/C
