Kinetic energy because the ball is in motion or moving with energy behind it... kinda like when you shoot a gun, the bullet is fired out of the muzzle with kinetic energy ( Punch ) and the bullet goes through a wall or something. Sorry but my math skills aren't very good to give complex calculations but I would recommend that you maybe talk to some of the top ranking math guys on the website. Maybe they can give you better help...
Anyways, I hope I have been helpful to you.
Answer:
f = 3.102 Hz
Explanation:
In this case you have that the required voltage is the maximum induced emf produced by the rotating generator.
In order to calculate the frequency of rotation of the generator that allows one to obtain 12.0V you use the following formula:
(1)
N: turns of the armature = 95
B: magnitude of the magnetic field = 0.800T
A: area of the square armature = (9.0cm)^2 = (0.09m)^2 = 8.1*10^-3 m^2
emf_max = 12.0V
w: angular frequency
you solve the equation (1) for w:
Then, the frequency is:
light waves. the other waves like gamma rays or infrared waves or radio waves are all not visible to the eye. light is the only thing out of those you can see.
Answer:
No image will be observed.
Explanation:
Images that are created by mirrors are virtual images. This virtual image can only be seen by an observer. In this case, an infinite number of images or no image will be created here as both will be reflecting their own images. Light will continuously bounce back and forth reflecting the same image.
