The electrons stop flowing
Answer:
Energy moves between the particle of the medium.
Explanation:
Answer:
D
Explanation:
A is wrong as otherwise the ocean would be black as light could not pass through it to create images.
B is wrong. This is a weird one as the electromagnetic spectrum attached below shows that radio waves have the least amount of energy vs gamma which has the highest and you can't really compare this to sound waves.
C just straight up false.
D is correct, no way to remember this, just learn it. a couple of facts about transverse waves of google. Electromagnetic waves are a type of transverse waves. These waves do not require a medium to travel. As the name of the waves imply, these waves show electrical and magnetic properties. No any charge occur in the waves. Electromagnetic waves work by the laws of reflection and refraction. They travel as straight lines in a vacuum at a speed of 3 x 10 8 ms -1.
Extra info:
As gamma waves have the highest energy it means that the waves are closer together (the wavelength is smaller) and they create more heat. Also gamma waves go through everything, X-ray only through skin and bounces of dense things like bones, which creates images. These eventually weaken more and more until radio waves do not pass through anything and just bounces around and everywhere which allows you to gain more coverage on a radio then on a cell phone.
Answer:
Approximately
.
Explanation:
By the Impulse-Momentum Theorem, the change in this woman's momentum will be equal to the impulse that is applied to her.
The momentum
of an object is equal to the product of its mass
and velocity
. That is:
.
Let
and
represent the velocity of the woman before and after the landing. Let
represent the woman's mass.
- The woman's momentum before the landing would be
. - The woman's momentum after the landing would be
.
Therefore, the change in this woman's momentum would be:
.
On the other hand, impulse is equal to force multiplied by the duration of the force. Let
represent the average force on the woman. The impulse on her during the landing would be
.
Apply the Impulse-Momentum Theorem.
- Impulse:
. - Change in momentum:
.
Impulse is equal to the change in momentum:
.
After landing, the woman comes to a stop. Her velocity would become zero. Therefore,
.
.
Answer:
kg m/s
Explanation:
e = Charge = C
V = Voltage = 
c = Speed of light = m/s
Momentum is given by

The unit of MeV/c in SI fundamental units is kg m/s
