Answer:
in general the largest mass M is located at the origin of the coordinate system.
Explanation:
The law of universal gravitation is
F = G m M / r2
Newton's second law is
F = m a
Where the acceleration is centripetal
a = v² / r
Let's replace
G m M / r² = m v² / r
M = v² r / G
The value of r is the distance between the two masses in interest, in general the largest mass M is located at the origin of the coordinate system.
This is because the body with more mass moves less than the body
Well, there's three classes of levers or ramps, whatever you'd prefer to call them and if an object is rolling down a ramp that is going straight down, that is where it will end up unlike a ramp that is tilted slightly to the left or right.
Explanation:
Half-life is the time taken for a radioactive material to decay to half its original composition:
Original mass = 48g
Half- life = 2hr
After four half lives;
Initially: 48g
First halving 24
Second halving 12
Third halving 6
Fourth halving 3
After second half life, we would have 12g
At fourth halving, we would have 3g
The object that had the most 1000 ton weight has the most momentum
