A rubber cube of volume 0.8cm3 falls vertically through 6m onto a concrete floor. The cube

experiences a maximum strain of 1.11% and remains in contact with the ground for 0.8s

before rebounding vertically upwards. Given that the cube impacted with the ground such

that one face of the cube was in complete contact with the ground, find the maximum EPE

stored in the cube at maximum strain.

Density of the cube = 0.9kgm-3​

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.

How to tell if two objects are in thermal equilibrium 1.the objects have the same temperature 2.the objects are the same size 3.the objects are touching each other 4.the objects temperatures are changing

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
