In collision type of problems since momentum is always conserved
we can say
So here along with this equation we also required one more equation for the restitution coefficient
so above two equations are required to find the velocity after collision
here the change in velocity occurs due to the contact force while they contact in each other
so this is the impulse of collision while they are in contact with each other while in collision which changes the velocity of two colliding objects
Increasing ; moving away
This indicates the light's wavelengths are (increasing) and the star or galaxy is (moving away.)
Idk im not very good at math
Answer:
3
Explanation:
half life, T = 12 million years
total life, t = 36 million years
Let n be the number of half lives.
n = Total life / half life
n = 36 / 12 = 3
So, the number of half lives are 3.
Answer:
Well your answer is peed not velocity because there is no direction
speed=0.086666666666667 m/s
Explanation:
Speed = distance/ time
7.8 m/ 90s
speed=0.086666666666667 m/s
