<h3>What is alpha decay?</h3>
The term alpha decay is the term that is used to describe a type of radioactive decay that involves the evolution of a helium nucleus. In this case the question is incomplete but I will try to paint a general picture of alpha decay.
The general equation for an alpha decay will produce a daughter nucleus that has an atomic mass less by four units and atomic number that is less by two units.

I agree with you the answer is A
Answer: Electric current
Explanation :
The direction of the magnetic field produced by an electric current will change when the direction of the electric current changes.
For example :
If a current is flowing in a straight length of wire, the magnetic field is described by a concentric circle (using right-hand rule).
Let the field lines are in the clockwise direction and when the direction of current is reversed then the direction of the magnetic field is in anticlockwise direction.
Answer:
Explanation:
Given
No of lines in the grating (N)=900 slits per centimeter
Distance between screen and grating(L)=2.78 m
Slit width(d) =
We know distance between two maxima
therefore
