Answer:
Explanation:
tha question is too hard simplfy it fast
the sodium chloride will be a crystal
it will have a giant crystal lattice
Answer:
The speed of the top of the wheel is twice the speed of the car.
That is: 72 m/s
Explanation:
To find the speed of the top of the wheel, we need to combine to velocities: the tangential velocity of the rotating wheel due to rotational motion
- with
being the wheel's angular velocity,
plus the velocity due to the translation of the center of mass (v = 36 m/s).
The wheel's angular velocity (in radians per second) can be obtained using the tangential velocity for the pure rotational motion and it equals:
Then the addition of these two velocities equals:

I'm pretty sure the answer to this question is "newton's first law of motion" or d. Hope this helps. :)
