Answer:
20N
Explanation:
The force (Hooke's Law) is proportional to the deformation. To extend the spring 4 times longer, you will need 4 times the force. In total, 20 N
water vapor that has condensed and covers the ground in the morning
Okay whats the question though?
As stated, the impulse and momentum definitions will be used to later find the value of time through the force of gravity. According to the theory, the impulse formula is given as,

Here,
F = Force
Change in time
Now using the impulse theorem we have that,
Change in Impulse = Change in momentum
(1)
The change in momentum is given as



The force due to gravity is through the Newton's second law

Here,
m = mass
g = Acceleration due to gravity
Substitute the value in (1)




Therefore it will take 0.51s.
