As shown in the figure, the area of the top bottom of a round table object is 2 / 5 of the area of the bottom. When it is placed on a table, the pressure on the table is 200 PA How much pressure does it put on the table?

As shown in the figure, the area of the top bottom of a round table object is 2 / 5 of the area of the bottom. When it is placed on a table, the pressure on the table is 200 PA How much pressure does it put on the table?

F is constant, f = PS, so 500 PA

A container with a bottom area of 100cm2 and a weight of 5N is placed on a horizontal table. The container contains 45N water with a depth of 40cm
Calculation: 1. The pressure of water 10cm away from the bottom of the container;
2. Pressure of container on horizontal table (g = 10N / kg)

1.P=ρgh=1*1000kg/m3*10N/kg*0.1m=1000Pa.
2.P=F/S=(45N+5N)/0.01=5000Pa

A thin-walled cylindrical container with a mass of 0.1kg and a bottom area of 100cm2 has 25cm liquid in the central container with a horizontal table top. The pressure of liquid on the bottom of the container is 1960p
Calculate the pressure of liquid density container to table top

According to P = ρ GH, H = P / GH = 7.84 * 10 & sup2; kg / M & sup3;
The pressure of the container on the tabletop includes the mass of the container. Here I take g as approximately 10
F=mg=ρgV+0.1=784*10*0.01*0.25=19.6 N
