A = (pi)(r)2
(dA/dt) = (2(pi)(r)) * (dr/dt)
(8) = (2(pi)(96)) * (dr/dt)
(dr/dt) = (1) / (24(pi))
By the use of wording "uniform" you are in fact stating that the tesselations are "regular"

If the cube is uniform ( ie it has uniform density) then the geometric center of the cube is its center of gravity.
The density of a non-uniform object can be found by using its mass and volume. The volume can be measured by placing the object in volumetric glassware filled with water. The increase in volume is equal to the volume of the object. The object can then be weighed using a scale. The density of the object will be given by the ratio of mass / volume.
The centripetal force on a particle in uniform circular motion increases with an increase in the mass of the particle or the speed at which it is moving. It also increases if the radius of the circle decreases, as the force required to keep the particle in the circular path becomes greater when the circle is smaller.

If the increase in speed is uniform, this means that the slope of the function of speed over time is constant. This means that acceleration is constant.
asthe current is continuosly changing in a uniform manner alternatively increasing and decreasing.
Workplace injuries, illnesses and death were increasing & No uniform or comprehesive las existed to protect againt workplace hazards
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
No. "Uniform motion" means motion at a constant speed in a straight line. But the speed of a body falling freely to the ground is continuously increasing, in response to the force of gravity.
When a centrifugal pump operates at its best efficiency point (BEP), the flow angles match with the impeller vane angles. At the BEP, the flow velocity in the volute is uniform around the volute (i.e., there is not acceleration of the fluid in the volute). Therefore, the pressure around the volute is uniform. The uniform pressure around the circumference results in a net zero radial force on the impeller (or the shaft). Note this is theoretical. In practice even at BEP, there is a small radial load because the pressure is not uniform. If the pump is operated away from the BEP, the flow velocities in the volute are non-uniform which results in a non-uniform pressure field and a net radial load (can be obtained by integrating the pressure around the circumference of the volute or the impeller).
