Explanation:
Certain automotive sensors like crank shaft position sensor uses a.c. while most automotive components require DC to work properly through the battery which is incorporated with an alternator to keep it charged through a diode while continual supply of DC is sustained.
A. A control group is given the experimental treatment.
Answer:
Force on the singly charged ion will be
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be
It is given that ion so charge on ion will be equal to
We have to find the electric force on the ion
Electric force is equal to , here q is charge and E is electric field
So force on the charge will be equal to
So force on the singly charged ion will be
