Water is stored in an open stored in an open storage tank. the absolute pressure in the tank above the liquid is 1.0 atm. the water level is 8m above the base of the tank. what is the instantaneous velocity of a fluid jet when a 0.5 cm diameter orifice is open at point a. the opening is 0.8m above the base. consider v1=0 at the instant the opening is made (1)

Describe the path of a ray that approaches a mirror parallel to the principal axis.

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
