Derive a formula for the bullet speedvin terms ofd, t, and a measured angleθbetween the position of the hole in the first disk and that of the hole in the second. if required, useπ, not its numeric equivalent. both of the holes lie at the same radial distance from the shaft.θmeasures the angular displacement between the two holes; for instance,θ=0means that the holes are in a line andθ=πmeans that when one hole is up, the other is down. assume that the bullet must travel through the set of disks within a single revolution.

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

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap
