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.

Answer:
22.5°C
Explanation:
Given height of Celsius thermometer is 20 cm.
As we know the limit of a Celsius thermometer is 100°C
It is given that total height of thermometer is 20 cm.
So, this limit that is 100°C should be equal to 20 cm.
°C
°C
°C
Now, we want to find the temperature when the level of mercury was 4.5 cm.
°C
°C
Hence, we have 22.5°C temperature in Celsius thermometer when height of mercury is 4.5 cm above the lower mark.
