Agymnast of mass 69.0 kg hangs from a vertical rope attached to the ceiling. you can ignore the weight of the rope and assume that the rope does not stretch. use the value 9.81 m/s2 for the acceleration of gravity. calculate in newtons: a) the tension t in the rope if the gymnast hangs motionless on the rope. b) the tension t in the rope if the gymnast climbs the rope at a constant rate. c) the tension t in the rope if the gymnast climbs up the rope with an upward acceleration of magnitude 0.700 m/s2.d) the tension t in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 0.700 m/s2.

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
