(asap will rate and ) compare the potential energy of a 5 lb ball at the top of a 5 foot hill and a 5 lb ball at the top of a 10 foot hill
a their potential energies are the same because they have the same mass.
b the ball at the top of the 5 foot hill has the least potential energy.
c the ball at the top of the 5 foot hill has the most potential energy.
d potential energy doesn't depend on a object's relative height.
2: which of the following has the most potential energy (only 3 answer choices)
a: a car at the top of a hilll
b: a car speeding down a hill
c: a person at the top of a hill

Which of the following are guidelines to follow for obtaining accurate observations

Which of the following will cause an induced current in a coil of wire? the constant field of the earth passing through the coil a magnet resting near the coil a magnet being moved into or out of the coil a wire carrying a constant current near the coil

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.
