Answer: how do you even type this so fast
Explanation:
Answer:
Option (c) : +f
Explanation:
Sign convention is based on cartesian system with Optical Centre as vertex, therefore, focal length of a convex mirror is +ive.
The general equation for voltage, field strength and distance is
<u>Explanation:</u>
Electric field is the measure of potential crossing per unit distance. In other terms we can say it as the work done to displace the charge from infinity to a point and the potential difference between them. The unit of Electric field is written as V/m, it is also known as field strength.
So the field strength is directly proportional to the potential and inversely proportional to the displacement or the distance covered by the charge. Thus, is the general equation relating voltage, field strength and distance.
Answer:
True
Explanation:
Liquid expands so therefore it is truee
