Of the three types of radiation listed below, which is the least penetrating and which is the most penetrating? -alpha -beta -ga

Vikentia [17]

Answer:

Alpha is the least penetrating radiation listed below.

Gamma is the most penetrating radiation in the given list.

These rays can be used to detect cancer, sterilizing the medical instrument, smoke detector, etc.

Radiation emitted from the radioactive elements also have very harmful. They affect the living being a lot. Waste from the nuclear reactor also contains harmful radiation which causes Land pollution if not disposed of properly.

$\theta=75^o$

Explanation:

<u>Net Force And Acceleration </u>

The Newton's second law relates the net force applied on an object of mass m and the acceleration it aquires by

$\vec F_n=m\vec a$

The net force is the vector sum of all forces. In this problem, we are not given the magnitude of each force, only their angles. For the sake of solving the problem and giving a good guide on how to proceed with similar problems, we'll assume both forces have equal magnitudes of F=40 N

The components of the first force are

$\vec F_1=$
