Answer:
0.006<357<700.003<6010<9256.0<9520.00
The strength of the gravitational forces between two masses depends on
-- the product of the masses,
-- the distance between their centers of mass.
Answer:
15.7m/s
Explanation:
To solve this problem, we use the right motion equation.
Here, we have been given the height through which the ball drops;
Height of drop = 14.5m - 1.9m = 12.6m
The right motion equation is;
V² = U² + 2gh
V is the final velocity
U is the initial velocity = 0
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
V² = 0² + 2 x 9.8 x 12.6
V² = 246.96
V = √246.96 = 15.7m/s
A, hope this helped! I didn’t really get it but I think it’s correct?
