Why can beta particles pass through materials more easily than alpha particles? (2 points)
2 answers:
Answer:
Beta particles are smaller.
Explanation:
When an unstable nuclei will break into stable nuclei then the nucleus energy of the unstable nuclei will be given to the the fast moving beta particles.
These beta particles are same as electron as they are negatively charged whose magnitude of charge is same as that of electrons charge.
so we have
now since electrons are smaller in size as we compare it with alpha particles so we can say that the beta particles can penetrate to more depth then the alpha particles
so here correct answer would be
Beta particles are smaller.

From ideal gas law, PV=nRT
where P is the pressure, V is the volume of the container, n is number of moles, R is the gas constant and T is the temperature.
Hence,
T= 110.65 k
Kinetic Energy =
K.E=
The energy an object has as a result of motion is known as kinetic energy.
A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transferred and is dependent on the mass and speed attained.
Kinetic energy can be converted into other types of energy and transported between objects. A flying squirrel may run into a chipmunk that is standing still, for instance. Some of the squirrel's initial kinetic energy may have been transferred to the chipmunk or changed into another kind of energy after the collision.
