· (b) A body at rest is given an initial uniform acceleration of 8.0m/s2 for 30 secs after which the acceleration is reduced to 5 m/s2 for the next 20s. The body maintains the speed attained for 60 secs after which it is brought to rest in 20 secs. Draw the velocity-time graph of the motion using the information given above.

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

Which atomic model was proposed as a result of j. j. thomson’s work?

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
