How long will your trip take if you travel 4000 m at an average speed of 8m/s

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

The signboard truss is designed to support a horizontal wind load of 735 lb. a separate analysis shows that 5/8 of this force is transmitted to the center connection at c and the rest is equally divided between d and b. calculate the forces in members be and bc. the forces are positive if in tension, negative if in compression.

During this chemical reaction energy is released. in the chemistry lab, this would be indicated by an increase in temperature or, if the reaction took place in a test tube, the test tube would feel warmer to the touch. reactions like this release energy because a) the reaction requires activation energy. b) the reactants have less potential energy than the products. c) the reactants have more potential energy than the products. d) the mass of the products is greater than the mass of the reactants.
