Answer:
He has 5,609,404 J of potential energy
Explanation:
P.E. = M*G*H
65 * 9.8^2 * 8800
Explanation:
The protons determines the atomic number which helps in identifying an atom of an element
White light is light that's made up of ALL colors.
If you have a source of white light and you want red light,
then you have to REMOVE all the other colors from the
white light somehow.
That's what a red filter does. The dye in the filter has chemicals
that absorb every color of light except red. Then, red light is the
only thing left to come out of the other side.
(If the light going into the filter had no red in it, then the filter
would appear black, because there wouldn't be any light
coming out of it at all.)
Answer:
1. v = 30 m/s
2. v = 5 m/s
3. f = 40 Hz
4. f = 400 Hz
5. f = 300 Hz
6. λ = 0.772 m
7. λ = 0.386 m
8. λ = 0.625 m
9. v = 100 m/s
10. v = 50 m/s
Explanation:
The relationship between frequency, wavelength, and speed of a wave is given by the following formula:

where,
v = speed of wave
f = frequency of wave
λ = wavelength
1.
f = 100 Hz
λ = 0.3 m
Therefore,
v = (100 Hz)(0.3 m)
<u>v = 30 m/s</u>
<u></u>
2.
f = 50 Hz
λ = 0.1 m
v = (50 Hz)(0.1 m)
<u>v = 5 m/s</u>
<u></u>
3.
v = 20 m/s
λ = 0.5 m

<u>f = 40 Hz</u>
<u></u>
4.
v = 80 m/s
λ = 0.2 m

<u>f = 400 Hz</u>
<u></u>
5.
v = 120 m/s
λ = 0.4 m

<u>f = 300 Hz</u>
<u></u>
6.
v = 340 m/s
f = 440 Hz

<u>λ = 0.772 m</u>
<u></u>
7.
v = 340 m/s
f = 880 Hz

<u>λ = 0.386 m</u>
<u></u>
<u></u>
8.
v = 250 m/s
f = 400 Hz

<u>λ = 0.625 m</u>
<u></u>
9.
f = 50 Hz
λ = 2 m
v = (50 Hz)(2 m)
<u>v = 100 m/s</u>
<u></u>
10.
f = 100 Hz
λ = 0.5 m
v = (100 Hz)(0.5 m)
<u>v = 50 m/s</u>
Answer:4N
Explanation:
mass=4kg
Acceleration=1m/s^2
Force=mass x acceleration
Force=4 x 1
Force=4N
