A cyclist is standing still at the top of the hill and begins to coast down the hill. The mass of the cyclist and bike is 64 kg. the cyclist gravitational potential energy is converted into kinetic energy with an efficiency of 48%.

1700 j of energy is lost from 0.14 kg object , the temperature decreases from 50°c to 45°c what is the specific heat of this object, amd what is the material ?

1which body contains the majority of the mass in the solar system earth jupiter the moon the sun 2 what keeps the objects in the solar system such as planets orbiting around the sun the force of gravity the galaxy exerts on all objects within it including the solar system the great distance between the sun and the planets the sun's nuclear fusion which acts on each object the gravitational force between the sun and each object in the solar system
