Our sister planet does not show plate tectonics on its surface to the degree our Earth does. What are possible explanations?
What will be an ideal response?
Perhaps the high temperature of the Venusian surface prevents the formation of rigid plates like on Earth. Maybe our hydrosphere is a critical lubricant for plate motions. Maybe the crust is thinner, so it is easier for lava to erupt as volcanoes like the coronae and prevent the convective cycle that causes plate movement.

A wall consists of 2 layers of material: brick in front of an equal thickness of wood
If the respective thermal conductivities of the brick and wood are 1.3 J/m-s-C and 0.15 J/m-s-C, how does the temperature gradient across the wood compare to the gradient across the brick?

A rod of length L is hinged at one end. The moment of inertia as the rod rotates around that hinge is ML2/3 . Suppose a 2.50 m rod with a mass of 3.00 kg is hinged at one end and is held in a horizontal position. The rod is released as the free end is allowed to fall. What is the angular acceleration as it is released?
