(wavelength x frequency = speed)
speed = 45 x 0.1
= 4.5 m/s</span>
Protons and neutrons are located in the nucleus, a dense central core in the middle of the atom, while the electrons are located outside the nucleus.
Answer:
A
Explanation:
It varies from person to person.
i think the data is not complete but that's according to me
Use the definition of acceleration:
Acceleration = (change of velocity) divided by (time for the change)
The graph says:
Change of velocity = -6 m/s
Time for the change = 3 sec
So Acceleration = (-6m/s) / (3 s)
That's -6/3 m/s•s
or
-2 m/s^2
