Work, which is required to move a body from a resting position, is called

A: kinetic energy
B: Potential Energy
C: Rotational Energy
D: Vibrational Energy

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

How have the greenhouse gasses increased from the year 2000 to 2018

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
