frequency
Everything is absorbing energy; Good emitters of radiant energy are also good absorbers-
poor emitters are poor absorbers
Answer:
The kite string is feet long.
Explanation:
Use the Pythagorean Theorem, which is .
Here the question is asking for , which would be the hypotenuse, or the longest side of the triangle.
So the would be , and the would be .
Plug those values into the formula, and that would get .
Now, solve for , which would equal .
That means we would have to solve for .
Square root both sides of the equation, getting .
Solve for , which would get us .
Hence, the answer to this would question would be .

It really doesn't matter how long the flight of stairs is. What we really need to know is how much height Mary gained, straight up. We don't know that. If we knew the height then the total amount of work she did would be 87 x the height in meters. The unit is joules. Then the power she delivered would be that number divided by the six seconds and that unit is watts.
By the way ... it's troubling that Mary's weight is only about 20 pounds. It's doubtful that such a tiny creature could run up a flight of stairs.
As we know that electrostatic force between two charges is given as
here we know that electrostatic repulsion force is balanced by the gravitational force between them
so here force of attraction due to gravitation is given as
here we can assume that both will have equal charge of magnitude "q"
now we have
now we have
