The base blocks exert the same pressure on the surface. Next, another red block is stacked on top of the red block and another blue block on the blue block, as shown in Figure 10A-4. This causes the pressure exerted by each stack of blocks on the table surface to ______. a.remain the same b.double c.decrease by half At the same time, the pressure exerted on the tabletop by the red stack is ______ the pressure exerted on the table by the blue stack. a.equal to b.half of c.double With the addition of equal numbers of like-colored blocks to their respective stacks, the slope between their top surfaces becomes ______ steep. a.more b.less (please only answer the last two subparts)
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
The base blocks exert the same pressure on the surface. Next, another red block is stacked on top of the red block and another blue block on the blue block, as shown in Figure 10A-4. This causes the pressure exerted by each stack of blocks on the table surface to ______.
a.remain the same
b.double
c.decrease by half
At the same time, the pressure exerted on the tabletop by the red stack is ______ the pressure exerted on the table by the blue stack.
a.equal to
b.half of
c.double
With the addition of equal numbers of like-colored blocks to their respective stacks, the slope between their top surfaces becomes ______ steep.
a.more
b.less
