The mass and related weight on the respective objects on four different planets is
4 kg, 40n, earth
6 kg, 24n, mars
2 kg, 50n, jupiter
4 kg, 36n, venus
a) based on the information given, explain why the gravitational force on earth is stronger than on venus.(3%)
b) explain the relationship between the weight and the gravitational force of the planet on the object.(2%)
c) predict what will happen if the mass of the four planets is the same(3%)

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

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?
