The amount of force required to stretch or compress the spring is known as the spring force. Its unit is Newton(N). Force is needed to stretch spring is 10.2 N.
<h3>What is spring force?</h3>
The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is
F = kx
The given data in the problem is;
F is the spring force =?
K is the spring constant= 8.5 N/m
x is the length by which spring got stretched = 1.2m
Hence the force is needed to stretch the spring is 10.2 N.

Displacement can be defined as the overall change in the position of the object. The displacement of the car in 5 hrs is 0 km.
Displacement:
It is a vector quantity that is defined as the overall change in the position of the object.
The formula for displacement is:
Where,
- total displacement
- final position
- initial position
In the given graph:
- Car displaces 15 km in 2 hrs
- Car displaces 20 km in 4 hrs.
- The car moves back to the initial position in 5 hrs.
Therefore, the displacement of the car in 5 hrs is 0 km.

Answer:
32
Explanation:
the atomic mass is the number of protons and neutrons in the nucleus of an atom
so we will add 16 + 16 = 32
Answer:
Heat is transferred directly from one particle of matter to another by the process of conduction.
A circular flow of warmer fluid and cooler fluid is called convection
Heat is always transferred from conduction to radiation
radiation is the transfer of energy by electromagnetic waves.
Heat that is transferred by the movement of currents within a fluid is called conduction
The only form of heat transfer that does not require matter is specific heat
Water bubbles up through a hot spring at Yellowstone National Park. What method of heat transfer is this?
convection
