What statements best define percent error? Check all that apply. - It is a mathematical way of showing accuracy.
- The higher the percent error, the more accurate the data set.
- The higher the percent error, the less accurate the data set.
- Only the experimental value is needed to calculate percent error.
- Only the actual, or accepted, value is needed to calculate percent error.
- A percent error always has a positive value.


It is a mathematical way of showing accuracy.
The higher the percent error, the less accurate the data set.
A percent error always has a positive value.

Got the question right on the test review!

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

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o
