Answer:
Explanation:
The energy difference between the energy levels involved in the transition of the electron is directly proportional to the frequency of the emitted photon:
Where h is the Planck constant. The photon's frequency is inversely proportional to its wavelegth:
Here c is the speed of light. Replacing (2) in (1):
The formula for velocity vf = vi + at
First list your given information
2m/s Is your initial velocity (vi)
6m/s is you final velocity (vf)
2 seconds is your time (t)
Since you want the a for acceleration get a by itself
a = (vf-vi)/t
So a= (6-2)/2
a= 4/2
a=2
Now units
the units for acceleration are m/s
2m/s

First let's convert the time in seconds:
The current is defined as the quantity of charge flowing through a certain section of a circuit per unit of time:
Using I=10 A, and
, we can find the amount of charge flown through the hair dryer in this time:
The charge of a single electron is
, so the number of electrons flown through the hair dryer is the total charge divided by the charge of a single electron:
