The problem is most likely that the commutator brushes bounces as the motor shaft rotates.
<h3>What is a DC motor?</h3>
This is referred to a device which converts direct current electrical energy into mechanical energy.
if the commutator brushes bounces as the motor shaft rotates over different materials, the ticking sound is heard.

Answer:) Calculate the acceleration of a skier heading down a. 10.0º slope, assuming the coefficient of friction for waxed.
Explanation:
I believe this is right I'm not sure so if I'm rong let me know please.
The mineral with Mohs hardness would be scratched because the mineral with Mohs 7 hardness is stronger than the Mohs 5 mineral. Eventually, that mineral would turn into dust if you kept rubbing it.
The energy to be dissipated is proportional to 1/2 m v^2 ie proportional to v^2 for the same car
<span>In turn F * d = work done. </span>
<span>F is constant ( same brakes) </span>
<span>so d is proportional to v^2 </span>
<span>if v is multiplied by 3 then d is multiplied by 3^2 = 9 </span>
<span>distance = 180m</span>
Answer:
i guess the body is not accelerating
