That is potential energy.
Gamma rays can pass through a lot
Answer:
P = 9800 [Pa]
Explanation:
In order to calculate the pressure at the bottom, we must use the following formula.
P = Ro*g*h
where:
P = pressure [Pa] (units of pascals)
Ro = density of the water = 1000 [kg/m³]
g = gravity acceleration = 9.8 [m/s²]
h = height = 1 [m] (because its half of the portion, the full height is 2 m)
P = 1000*9.8*1
P = 9800 [Pa]
Answer:
129.96
At a Gravitational acceleration of 32.17405 ( which is the normal rate for a freefall) you will geta velocity of 129.96 and the time of fall will be 4.039 seconds from 80 meters.
Why is the weight of a free falling body zero? It is not, an object in free fall will still have a weight, governed by the equation W = mg, where W is the object's weight, m is the object's mass, and g is acceleration due to gravity. Weight, however, has no effect on an objects free falling speed, two identically shaped objects weighing a different amount will hit the ground at the same time.
Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!
