Answer:
The mass of the ball is 1.360 kilograms.
Explanation:
By Work-Energy Theorem, gravitational potential energy (
), in joules, is the product of weight of the ball (
), in newtons, and height (
), in meters. Please notice that weight is the product of the mass of the ball (
) and gravitational acceleration (
), in meters per square second. Then, the formula for the mass of the ball is:
(1)
If we know that 
, 
and 
, then the mass of the ball is:
The mass of the ball is 1.360 kilograms.
ligma nuts is it the answer bro ;)
Answer:
d) 1000 times
Explanation:
As we know that difference of sound level is given as
so here we need to find the ratio of two intensity
it is given as
now we have
so it is
d) 1000 times
Weight = (mass) x (gravity)
Weight = (8 x 10⁻⁴ kg) x (10 N/kg) = 0.008 Newton
