Answer: Its A because i had the same question and it was a
2nd stone time = 13.0/9.8 = 1.33 seconds
distance = 0.5*9.8*1.33^2 = 8.67 meters
1st stone time = 1.33+1.5 = 2.83 seconds
distance = 0.5*9.8*2.83^2 = 39.24 meters
39.24-8.67 = 30.57 meters apart

Answer: Positive acceleration</h2>
Acceleration is the variation of velocity over time .
Now, it is said that a body has a <u>positive acceleration</u>, when the velocity of the body increases, that is, when the final velocity is greater than the initial velocity.
It is then said that it is an accelerated movement.
ITS 20,000 from the test that i took and got it right.hope this helped..
Convection currents are driven by the buoyancy
that results from density differences.
