Answer:
his results in the final angle after the collision of 37.2 degrees basically what we did there is turn the vector into a right triangle. We use sohcahtoa to solve for the angle. Being.

Explanation:
Radioactive decay is a phenomenon that occurs when a certain isotope of an element, said to be radioactive, decays, turning into a lighter nucleus and emitting radiation + energy in the process.
The radioactive decay of this isotope of polonium is described by the equation

where
is the amount of polonium left after time t
is the amount of polonium t time t = 0
is the half-life of the polonium, in days (it is the time it takes for the initial element to halve its amount)
IN this problem, we know that:
After t = 560 days, the amount of polonium left is
. Therefore, we can re-arrange the equation, substituting t = 560 d, and solve for
to find the initial amount of polonium:

When the vibration is in a direction parallel to wave's motion that is a Longitudinal wave (C).
But When the vibration is in a direction perpendicular to wave's motion then it is Transverse wave.
