According to the Hooke’s law formula, the force is proportional to what measurement?
2 answers:
Answer: The correct answer is the displacement of the spring.
Explanation:
Hooke's Law is used to determine the force applied when a spring is compressed or extended. The formula for Hooke's Law is given by the equation:
Removing proportionality sign,
where,
F = force applied on the spring
k = Spring constant
x = Compression or extension of the spring. In other words it is the displacement of the spring.
Hence, from above relation, it is visible that force is directly proportional to the displacement of the spring.

Answer:
a)188.65m
b)154.35m
c)243.7m
Explanation:
Given data:
(a) The distance from the kicker to each of the 2 spectators is given by:
where,
v= speed of sound
=time taken for the sound waves to reach the ears
m
(b)
where,
v= speed of sound
=time taken for the sound waves to reach the ears
(c)As the angle b/w slight lines from the two spectators to the player is right angle,
hypotenuse=the distance b/w 2 spectators
and, the slight lines are the other 2 lines
