The extension is
Explanation:
From the question we are told that
The length of the wire on a winter day is
The temperature on the winter day is
The temperature on a summer day is
The the extension of the wire on a summer day is mathematically represented as
Where
is the coefficient of linear expansion of copper with a values
substituting value
Answer:
The amount of force acting on the spring.
Explanation:
Here, Fspring= kΔx is a equation denoting the amount of force acting on the spring.
where, k = spring constant.
Δx= change in the length of the spring.
so, for every Δx change in spring length, kΔx force acts on the spring.

The most effective forces on the object are the backward force of air resistance relatively very small in magnitude, and the force of gravity. Because the spiral path of the satellite is not perpendicular to the gravitational force, one element of the gravitational force pulls forward. at the satellite to do fantastic work & make its speed increase.
<h3>What is called gravitational force?</h3>
Gravity, additionally referred to as gravitation, is a force that exists amongst all material gadgets withinside the universe. For any objects or particles having nonzero mass, the force of gravity tends to draw them in the direction of each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.
