Sinc the elevator is moving at constant velocity, it experience no net force and thus no net acceleration is experienced by the elevator. a=0ms^-2
The volume of the rock has a deeper density than the cylinder.
B) atmosphere pressure, i believe
Answer:
8 m³
282.3 ft³
Explanation:
The volume of each box is width times length times depth:
V = (1 m) (2 m) (1 m)
V = 2 m³
There are four boxes, so the total volume is:
4V = 8 m³
Converting to cubic feet:
8 m³ × (3.28 ft / m)³
= 282.3 ft³
Answer:
The mass of the sand that will fall on the disk to decrease the is 0.3375 kg
Explanation:
Moment before = Moment after
where;
I is moment of inertia = Mr² = 0.3 x (0.3)² = 0.027 kg.m²
substitute this in the above equation;
Therefore, the mass of the sand that will fall on the disk to decrease the is 0.3375 kg
