Answer:
1. the force which can be felt or act only when two objects are in contact is known as contact force.
for example: frictional force, muscular force,
tension, air resistance .
2. the force which can be felt or act even when two objects are in contact or not is known as non-contact force.
for example: magnetic force, gravitational force, electrostatic force.
Surveys are considered the most reliable way to gather data
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

55
N
Explanation:
We use Newton's second law of motion here, which states that,
F
=
m
a
m
is the mass of the object in kilograms
a
is the acceleration of the object in meters per second
F
=
