Carole is surprised when she makes an emergency stop and the tissue box that had been in the back window of her car hits the back of her seat. how would newton explain what happened?
a) an object in motion tends to stay in motion.
b) the force of stopping caused it to accelerate.
eliminate
c) box mass and inertia accelerate with the force.
d) every action has an equal and opposite reaction.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
