Answer:
approximately 304358
Explanation:
wavelength = speed / frequency
speed of an electromagnetic wave is 299,792,458 m/s in a vacuum
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:
'Heat' is another term to describe thermal energy, whether the thermal energy
just sits in some object or substance, or flows from one object to another one
that's cooler.
'Heat' is NOT another word for 'Temperature'. If you think of it that way,
then you'll have a hard time UNlearning that idea and getting yourself
unmuddled and straightened out. Please don't even go there.
Newton is a unit of force. Joules is an amount of work which is equal to the force times distance, or newton meters. So the product of newtons and meters makes joules.
