gravitational potential energy is given by formula

here we need to compare the gravitational potential energy of stone 2 with respect to stone 1
so we will say


given that

now we have

Answer:
The speed is 173 m/s.
Explanation:
Given that,
A = 47
B = 14
Length 1 urk = 58.0 m
An hour is divided into 125 time units named dorts.
3600 s = 125 dots
dorts = 28.8 s
Speed v= (25.0+A+B) urks/dort
We need to convert the speed into meters per second
Put the value of A and B into the speed




Hence, The speed is 173 m/s.
When Ag(silver) reacts with CuCl2, Ag displaces Cu from CuCl2 and forms AgCl which is soluble and brownish red solid precipitate is left in the solution.
Hence option D is correct.
Hope this helps!
Answer:
South and West
Explanation:
Those people are pushing the hardest. It will move south faster than it moves west.
Answer:
Explanation:
My speed after the interaction will depend upon the impulse the ball will make on me . Now impulse can be expressed as follows
Impulse = change in momentum
change in momentum in the ball will be maximum when the ball bounces back with the same velocity which can be shown as follows
change in momentum = mv - ( - mv ) = 2mv
So when ball is bounced back with same velocity , it suffers greatest impulse from my hand . In return , it reacts with the same impulse on my hand pushing me with greatest impulse according to third law of motion. this maximizes my speed after the interaction.
