Answer:
I'm Pretty sure the answer your looking for is C
Answer:
E = 1.38 x 10⁸ eV = 138 MeV
Explanation:
The energy associated with the given wavelength can be found from the following formula:

where,
E = Energy of electron = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = Speed of Light = 3 x 10⁸ m/s
λ = wavelength = 9 fm = 9 x 10⁻¹⁵ m
Therefore,

<u>E = 1.38 x 10⁸ eV = 138 MeV</u>
297.729km :-) hope this helps
Answer:
2.25m/s
Explanation:
wavelength=4.5m
period=2sec
frequency= 1/period
=1/2
speed= wavelength×wave frequency
=4.5×1/2
=2.25 m/s
so, none of the options are correct
When block is pushed upwards along the inclined plane
the net force applied on the block will be given as

here we know that
m = 75 kg


now plug in all values into this


now for finding the power is given as
