What does K stand for in Hookes law?
2 answers:
Answer:
Spring Constant
Explanation:
Hooke's law: The force required to squeeze or expand a spring by a distance (d) is directly proportional to the distance. It is given as,
Here, K = spring constant.
It is measure of the stiffness of the spring. If we draw the graph of Force with respect to the distance it will be a linear plot passing through the origin. The slope of the plot will be equal to K.

Orbital period of satellite is 5.83 x 10³ s
Explanation:
The orbital period of satellite revolving around Earth is given by the equation :
.....(1)
Here R is radius of Earth, h is height of satellite from the Earth's surface, M is mass of Earth and G is gravitational constant.
In this problem,
Height of satellite, h = 500 km = 500 x 10³ m
Substitute 6378.1 x 10³ m for R, 500 x 10³ m for h, 5.972 x 10²⁴ kg for M and 6.67 x 10⁻¹¹ m³ kg⁻¹ s⁻² for G in equation (1).
<em>T</em> = 5.83 x 10³ s
