Answer:
it would be rotation I think
He will swim 180m if he stays at a constant rate of 30m/min
Explanation:
First I’m going to use 6 min for the 5min 60s
Then if he swims 30m/min then I’m 6min, 30•6 he’ll swim 180m
Hope this helps!
Answer:
A biased person favors one side or issue over another.
Explanation:
For example say there is a soccer game going on Blue Team VS Red Team,
and the ref wants the Blue Team to win, so he helps the Blue Team win the calling fouls for them or not calling foals for the Red Team.
He is being biased.
Answer:
The wavelength of the light is 555 nm.
Explanation:
according to Bragg's law..
n×λ = d×sin(θ)
n is the fringe number
λ is the wavelength of the light
d is the slit separation
θ is the angle the light makes with the normal at the fringe.
Answer:
Explanation:
The de Broglie wavelength is given by the following formula:
(1)
Where:
is the Planck constant
is the momentum of the atom, which is given by:
(2)
Where:
is the mass of the electron
is the velocity of the electron (we are told it is 1/10 the speed of light )
This means equation (2) can be written as:
(3)
Substituting (3) in (1):
(4)
(5)
Now, we only have to find :
(6)
<u>Finally:</u>
>>> This is the de Broglie wavelength of an electron.
