Answer:
It exerts pressure everywhere inside the container.
Explanation:
Pressure is the forelce exerted by a body per crossectional area,ie pressure is force/area.In fluid system an important law that explains the behavior of fluid in a closed vessel is the Pascal law.It state that a liquid in a containing vessel exerts pressure undiminished in all direction in a vessel and to all portion of the fluid.
Answer: 5m/L^2
Explanation:
Inertial I = mr^2 where r = distance from axis of rotation, while m is the mass of the object.
I = 2[m(1L/2)^2] + 2[m(3L/2)^2] = 2m×. 25/L^2+ 3m×2. 25/L^2= 0. 5m/l^2 +4. 5m/l^2
= 5m/l^2.
