A 6 kg block is attached to a massless rope that passes over a frictionless pulley. The pulley can be modeled as a uniformly dense solid cylinder with a mass of 4 kg that rotates around an axis passing through its center. The other end of the rope is wound around a uniformly dense solid sphere with a mass of 10 kg and a radius of 6 cm. When released from rest the block will fall and the sphere will rotate as the rope unwinds from it. The rope will pass over the surface of the pulley without slipping. What is the effective mass of this system (in kg)?

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
