A light inextensible rope is used to pull a particle of mass 2 kg along a rough horizontal plane. Given the tension in the rope is 27 N and acts at an angle of 30° above the horizontal and that the particle is moving with an acceleration of 10 m s - , what is the coefficient of sliding friction between the particle and the surface?

7.study the scenario. a small container of water with a low temperature is poured into a large container of water with a higher temperature. which choice correctly explains what happens to the thermal energy of these systems? the smaller container of water has more heat and thermal energy than the larger container. some heat and thermal energy is transferred to the larger container of water. the larger container of water has more heat and thermal energy than the smaller container. some heat and thermal energy is transferred to the smaller container of water. the larger container of water has more thermal energy and some of that energy is transferred to the colder water in a process known as heating. the smaller container of water has more thermal energy than the larger container, and some of that energy is transferred to the warmer water in a process known as heating.
