Which of the following is ALWAYS true. a) An object experiencing a constant negative acceleration has a decreasing momentum. b) If an object has a constant acceleration, its kinetic energy is changing at a constant rate. c) If an object has a zero net force acting on it, its kinetic energy is constant. d) If an object's kinetic energy is constant, there is no net force acting on it. e) If an object's kinetic energy is increasing there is a...

you plot the position(x) vs. time(t) for an object moving at a constant acceleration. Will the slopes (velocity) be constant or not? why?

Choices: True or False. If velocity is zero then acceleration must be zero too. If speed...

Choices: True or False. If velocity is zero then acceleration must be zero too. If speed is constant then acceleration is zero. If velocity is constant then speed must be constant too. If speed changes then velocity must change too. Object slows down if it's acceleration is negative. If speed is constant then velocity must be constant too.

Show that if the acceleration is always perpendicular to the speed, the speed is constant.

For each statement below circle TRUE if the statement is true, otherwise circle FALSE.

For each statement below circle TRUE if the statement is true, otherwise circle FALSE. A hypothesis test uses data from a sample to assess a claim about a population. A randomization distribution will be centered at the value used in the null hypothesis. “Failing to reject the null hypothesis” and “accepting the null hypothesis” mean the same thing in a hypothesis test’s conclusion. The p-value is the probability, assuming the alternative hypothesis is true, of obtaining a sample statistic as...

An object moving with uniform acceleration has a velocity of 10.0 cm/s in the positive x-direction when its x-coordinate is 2.73cm. If its x-coordinate 2.95 s later is −5.00 cm, what is its acceleration?

(True and False) Circle the correct answers. (True or False) A continuous metric is one derived by counting something. (True or False) Categorical data is nominal data. (True or False) The tracking signal is the MAD divided by the running sum or errors. ((True or False) Ordinal data are ranked according to some relationship to one another. (True or False) Observations that radically different than the rest are called outlaws. (True or False) The second quartile and median are the...
