Answer:
240
Explanation:
We know that Y is 800m from X, and located 400m north of X.
That means the cosine of the bearing of Y from X is 400m/800m = 1/2
We should remember (or use a calculator with arccos) that the angle for which the cosine is 1/2 is 60deg.
The bearing of Y from X is 060.
To get the bearing of X from Y, we just need to add or subtract 180 and we arrive at the answer - 240
We need the frequency of the photon, it is v = c/ λ
Where c is 3 x 10^8 ms^-1 and λ
is the wave length
We also need the expression of
connecting frequency to energy of photon
which is E = hv where h is Planck’s
constant
Combining the two equations
will give us:
E = h x c/λ
Inserting the values, we will
have:
E = 6.626 x 10^-34 x 3 x 10^8 /
0.126
E = 1.578 x 10^ -24 J
The answer is D. Tension force :))
