Answer:
20m
Explanation:
Pressure = pgh
p = density of water 1000
kg/m^3
g = acceleration due to gravity 9.81 m/s^2
h is the depth of water
Pressure = 201 kPa = 201 x 10^3 Pa
201 x 10^3 = 1000 x 9.81 x h
201 x 10^3 = 9810h
h = 20.49 m
Approximately 20 m
In the modern model of the atoms over 99.9℅ of the atom is made up of empty space
Since momentum is equal to mass multiplied by velocity, you would mulitply 250 grams by 68 m/s.
The answer is 17,000 kg*m/s
