The velocity of light is v = 3 x 10⁸ m/s.
The given wavelength is λ = 0.86 nm = 0.86 x 10⁻⁹ m.
Note that
v = fλ
where f = frequency.
Therefore
f = (3 x 10⁸ m/s)/(0.86 x 10⁻⁹ m)
= 3.488 x 10¹⁴ Hz
Answer: 3.49 x 10¹⁴ Hz
The one with the greatest mass would, when everything else is equal. I'm having trouble making out your list of choices.
Answer:A material that can dissolve in another material called Soluble
Explanation:
Answer:
1.315 m
Explanation:
Assumption: there is no resistance of any type
v= 5.08 m/s
g = 9.81m/s^2
change in kinetic energy = change in gravitational potential energy
mass on both side is same so it cancels out
and also making 'h' alone on one side
h= ((5.08)^2)/(2*9.81)
h =1.3153m
