A). 6,000 Hz.
No. This is in the middle of the human hearing range. If a radio station were transmitting on this frequency, then every wire and cable in town would pick up a little of its energy, and you'd hear it on every telephone, earbud, and headphone, and it would come out of every loudspeaker.
B). 6,000,000 Hz. (6 mHz)
No. This isn't used by 'commercial' broadcasting stations, but it IS used by
foreign short-wave stations, to broadcast news, 'culture', and propaganda
into other countries.
C). 60 Hz.
No. This is the frequency of the AC that you use when you plug anything
into a wall socket. All of the electric company's power lines RADIATE a
little bit of energy at this frequency, so it wouldn't be a very smart frequency
for a radio station to try to use, since the whole country is already blanketed
with interference at this frequency.
D). 600,000 Hz (600 kHz)
Yes ! This is the "600" or "60" or "6" that's marked
near the left end of your AM radio dial.
yay !
lol if not LOVE then its , strongest fundamental force is the strong nuclear force; it is 100 times stronger than the electromagnetic force.
hope this helps:)sorry if it doesnt

Answer:
See Below.
Explanation:
I can't transpose the diagram onto Brainly. I'll do my best to describe what is going on.
- Draw a horizontal line one inch from the each border of the page.
- To show what each of A and B are supporting, use an up arrow.
- Label the Ends A and B. B is on the right side.
- Put the physics teacher about 1.5 inches from B. His force goes down.
- Label it as 75 * 9.8 Newtons
- Put the platform mass about 2.5 inches from B
- Label it as 10 * 9.8 Newtons
- B is the balance point
- Now put in the distances. The lines are horizontal
- Student A: 10 meters
- Center of mass: 4 meters to B
- Mass of Physics: 2 meters.
Now you are ready to develop the equation
Clockwise
There is only 1 force where B is the Balance point that is going clockwise
10 * Force A
The AntiClockwise Moments
Platform: 4*10kg * 9.8 = 392 N m
Physics T: 2 * 75 * 9.8 = 1470 N m
So the Anti Clockwise moments = the clockwise moments.
10 * Force A = 392 NM + 1470NM Divide by 10. Remember that is in meters
Force A = 1862 N M / 10 10 M = 186 N
Does that make some sort of sense? It should Student A is the furthest distance from where all the action is at B. Therefore he is carrying the lightest weight.
Now what is the total force?
(75 + 10 ) * 9.8 = 85 * 9.8 = 833
This is one of those strange things that won't make sense until it does. Read the next sentence carefully. B is carrying most of the weight. Remember Newtons measure weight.
Support of A = 186 N
Support of B = x
Total of A+B = 933
186 + x = 833
x = 933 - 186
x = 647
So the forces are
A supports 186
B supports 647
