Exoplanets (planets outside our solar system) are an active area of modern research. suppose astronomers find such a planet that has the same mass as earth, but has a radius that is about 10% less. roughly, what acceleration due to gravity would you expect if you were standing on the surface of this new planet?

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
