In the direction the force is directed towards. If the boy kicks the ball to the right, the ball will roll to the right.
Answer:
vf=94.4 m/s
Explanation:
acceleration is the final velocity minus initial velocity divided by time
a = (vf-vi)/t
Given:
a= 14.2 m/s^2
vi= 0 (at rest)
t = 6.6
Solve for vf
a = (vf-vi)/t
a*t=vf-vi
(14.2)*(6.6)=vf - 0
vf=94.4 m/s
Answer:
The answer is explained below.
Explanation:
The energy emitted during the de-excitation of an electron from a higher energy level to a lower energy level is directly proportional to the frequency of the emitted light.
Here, the total sum of the energies of 2 frequencies of light emitted in different stages is equal to the energy of a single frequency of light during the de-excitation of fourth level to ground level directly.
Hence the total sum of of the frequencies of 2 lights emitted in different stages is equal to the frequency of single frequency of light emitted during the de-excitation from fourth level to ground level directly.
The some of the energies of 2 frequencies emitted by one electron is equal to the energy of a single frequency when electron jumps directly.
That's called 'parallax'.
To see it happen, go outside, hold your arm straight out in front
of your face and stick your thumb up. Close one eye, and notice
where your thumb appears against the houses across the street.
Now, don't move your arm, but just close the first eye and open
the other one. You'll see your thumb jump in front of a different
house. The angle that your thumb appeared to move is its parallax.
