Answer:

Explanation:
We are given that
Mass of one asteroid 1,
Mass of asteroid 2,
Initial distance between their centers,d=13.63 R
Radius of each asteroid=R
d'=R+R=2R
Initial velocity of both asteroids

We have to find the speed of second asteroid just before they collide.
According to law of conservation of momentum




According to law of conservation of energy







Hence, the speed of second asteroid =
Answer:
True
Explanation:
Examples of numerical data are height, weight, age
Answer:
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Explanation:
There are several different methods, depending on the particular situation. A few that might occasionally be useful include:
-- Read the label on the package.
-- Measure the mass and multiply by the local acceleration of gravity.
-- Measure the mass AND the local acceleration of gravity, then multiply.
-- Place the object or sample on a bathroom scale.
-- Place the object on one end of a symmetrical see-saw. Through trial and error, determine the weight required on the other end to balance the system.
Answer:
Acceleration = Final velocity-initial velocity/time
In m/s^2
a = 40000-0 /10
= 4000m/s
in km/h
a = 40/10÷360
= 1440km/h
