B. Reversing the current direction will cause the force deflecting the
wire to be perpendicular to the magnetic field but in the opposite
direction.
Since the connection is in series, the current divider can be used. It's mathematical expression is In = (It Rt) / Rn. If the value for is solved, power dissipation can also be solved using P = I^2 R.
I = 0.47 A
A. P = (0.47)^2 (5) = 1.11 Watts
B. P = (0.47)^2 (9) = 2 Watts
C. P = VI = 16(0.47) 4.24 Watts
The Answer would be false! electromagnet does attract to iron
Answer:
a. The kinetic energy of the system is zero.
Explanation:
It starts with a system with two substances or reactants (ex: A and B), which interact and produce different substances or products (ex: C and D) through a chemical reaction, that can release or consume energy. When that system reaches <u>chemical equilibrium</u> the amount of reactants and products is the same, therefore a balance is reached, and there is no more changes in the system. Which means the <u> kinetic energy of the system is zero.</u>
