A block with a weight of 36 N is placed on a sheet of aluminum with an inclination of 18°. The coefficients of static and kinetic friction between the block and aluminum are 0.35 and 0.23, respectively. Will the block slide down the plane?No. The downward force along the plane is 11 N and the maximum static friction force is 12 N. No. The downward force along the plane is 11 N and the maximum static friction force is 12 N.
Yes. The downward force along the plane is 34 N and the maximum static friction force is 2.6 N.
No. The downward force along the plane is 3.9 N and the maximum static friction force is 34 N.
Yes. The downward force along the plane is 11 N and the maximum static friction force is 7.9 N.

Which of the following represents a virtual image?

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
