K = ∆F / ∆s = 4N / 0.08m = 50N/m
While no one knows why, astronomers do now know that the solar nebula has collapsed. Scientists believed that our Solar system was made when gas and dust cloud was being disturbed by an explosion of supernova. Due to pressure, this cloud collapsed.
I’m pretty sure one increases just straight up velocity and the other is kind of a deceleration
Answer:
7 s
Explanation:
u = Initial velocity of rock = 12.2 m/s
= Angle of throw = 
x = Displacement in x direction = 25 m
Displacement in x direction is given by
Time taken to reach the ground is 7 s.
