Answer:
The image result of an object reflected by a convex mirror is typically virtual, upright, and smaller. Discover how moving the object farther away from the mirror's surface affects the size of the virtual image formed behind the mirror
Explanation:
Silver is a very good conductor, this means its resistivity is very low (from table, we can check the precise value, which is

).
Pure water, instead, is a very bad conductor, this means its resistivity is very high, of order of

(

). Even without knowing the precise value of the pure water resistivity, we can estimate the ratio between the pure water resistivity and the silver resistivity by comparing the two orders of magnitude:

Therefore, we can say that the correct answer is
The net force = sum of all forces acting on the body
If we take left side as -ve and right side as +ve,
then,
The net force here would be equal to,
10N + (- 3N)
= 7N.
Therefore, a net force of +7N ( + indicates it's moving towards right) is acting on the book of mass 2kg.
answer would be C. multiply the input force.
