The number of protons and neutrons in the nucleus stays the same when a β particle is released, but the number of neutrons is reduced by one and the number of protons is increased by one.

A daughter nucleus Q with mass number A and atomic number Z+1 is created when a radioactive nucleus P with mass number A and atomic number Z emits a beta particle.

(a) There is no conservation of the atomic number Z. It has been raised by one.

(b) There is conservation of mass number A.

Outcome:

Thus, it is evident from the discussion above that mass number (A) does not increase or decrease following beta decay.

Appropriate Choice: A
Since a multimeter is a test instrument used to measure two or more electrical values, primarily voltage, current, and resistance, this choice is accurate.

The particle’s direction is always relative to the lines of the electric field.

In the electromagnetic wave spectrum, wavelength and frequency have an inverse relationship.

The process by which unpolarized light becomes polarized is known as polarization of light. Only one plane is vibrated by polarized light. The magnetic and electric components of light waves vibrate perpendicular to each other, making them transverse waves. Light only vibrates in one plane when it is polarized. Therefore, light’s polarization indicates that it is electromagnetic.

Area of the cross-section A=π(d/2)2=π(0.05 mm/2)2=π×0.0025mm2 /4 ≈0.00196 mm2
This wire has the smallest cross-sectional area because it has the smallest diameter of any of the available options. As a result, under the same tension, it will extend to its maximum.

The rate at which an object’s velocity changes in relation to time is called acceleration. It is calculated by dividing the velocity change by the time it takes for the change to occur. The SI unit of acceleration is meter per second per second (m/s2) since the SI unit of velocity is meter per second (m/s) and the SI unit of time is second (s).
