A boat passes under a bridge. At the instant the boat passes from under the bridge an arrow is fired horizontally, striking the boat after 0.0128 hrs. The boat traveled 0.072 km in the same time the arrow was in the air. (Assume a = -10 m/s2) Calculate the boat’s velocity in m/s. Show all conversions with cancellations (3 pts; 1 pt formula, 1 pt setup with cancellations, 1 pt answer)

In m/s, what must the horizontal velocity of the arrow be in order to strike the boat as stated in the prompt? Justify your answer. (1 pt)

What is the initial vertical velocity of the arrow? Justify your answer. (1 pt)

How far does the arrow fall? (3 pts; 1 pt formula, 1 pt substitution, 1pt answer)

What is the vertical velocity of the arrow just before it strikes the ground? (3 pts; 1 pt formula, 1 pt substitution, 1 pt answer)

The current in a hair dryer measures 11 amps. the resistance of the hair dryer is 12 ohms. what is the voltage?unit:

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
