Answer:
8.6*10^5N
Explanation:
Pressure of the water = density of water * height of the water * acceleration due to gravity
Pressure of water = 1000*9.81*(2.5 + 8.50)
Pressure of the water = 107910 = 1.08*10^5
And Pressure = force / A
Force = Pressure * A(surface area of the container)
Force = 1.08*10^5 * 8 = 863280 = 8.6*10^5N
When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. ... Air resistance depends on two important factors - the speed of the object and its surface area.
True. The mass of an electron is about 1/2000 amu whereas the mass of a proton is 1 amu.
