Speedy sue, driving at 33.0 m/s, enters a one-lane tunnel. she then observes a slow-moving van 160 m ahead traveling at 5.20 m/s. sue applies her brakes but can accelerate only at −1.50 m/s^2 because the road is wet. will there be a collision? yes no. if yes, determine how far into the tunnel and at what time the collision occurs. if no, determine the distance of closest approach between sue's car and the van. (if no, enter "0" for the time.)

Phase changes are chemical changes. true or false

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

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?
