Carly is investigating the effects of heat transfer on molecular motion. She pours cold water into a beaker, places the beaker on top of a heat source, and turns on the heat. Her set up is shown. Identify and describe the method of heat transfer that Carly is investigating. Describe the effect of the heat transfer on the motion of the water molecules at the top and the bottom of the beaker.

Alow cost, low earth orbit (leo) satellite is to be fabricated at a university, for subsequent launch by rocket. what are the constraints and objectives for selection of a material suitable for the satellite bus (i.e. the structure)? explain each in brief. (15 marks) b)suggest sources of data which could support the selection of materials for applications in space. (5 marks) c) set weights for the objectives listed in (2a) using the digital logic method. (5 marks)

Calculate the kinetic energy of earth due to its spinning about its axis. krot = j compare your answer with the kinetic energy of the orbital motion of earth's center of mass about the sun. assume earth to be a homogeneous sphere of mass 6.00 1024 kg and radius 6.40 106 m. the radius of earth's orbit is 1.50 1011 m.

How is the gravitational force related to the distance between two objects?
