the answer would be B. the back emf increases, and the current drawn from the socket increases
more current is needed to make the motor move, like when you try to self crank a motor and the back wires are touching its harder to crank. and the emf increases since more current is being drawn in, strengthening the emf or increasing the emf
1. <span> Fp = Mg*sin24 = 0.407Mg. </span>
<span>Fn = Mg*Cos24 = 0.914Mg. </span>
<span>Fk = u*0.914Mg. </span>
<span>Fp-Fk = M*a. </span>
<span>0.407Mg-u*0.914Mg = M*a.
</span>Divide by Mg:
<span>0.407-0.914u = a/g = 3.1/-9.81, </span>
<span>0.407-.914u = -0.316, uk = 0.791.
</span>
2. <span> M*g = 1200*9.8 = 11,760 N. = Wt. of car. = Normal force(Fn). </span>
<span>Fp = Mg*sin 0 = 0. </span>
<span>Fk = uk*Fn = 0.1323*11,760 = 1556 N. </span>
<span>Fp-Fk = M*a. </span>
<span>0-1556 = 1200a, a = -1.30 m/s^2. </span>
<span>V^2 = Vo^2 + 2a*d. </span>
<span>0 = (20.1)^2 - 19.6d

Answer:
The answer is A) True
Explanation:
Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal found in rocks worldwide. Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart.
Answer:
The characteristics of water waves is that it travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases.
Explanation:
Mass is number 2. Vector is 5. Force is 3. Weight is 1. Net force is 6. magnitude is 4.
