Two equations for this one: Q=CV  & PE=(1/2)QV. 
C=750 * 10^-6 F , V=330 V . 
so if you use Q=CV=(<span>750 * 10^-6)(330). Q=0.2475

Then solve for PE. PE=(1/2)QV= (1/2)(0.2475)(330)= 40.8 J
So PE=40.8 J</span>

-- It takes the brick 8.9 seconds to reach the ground. 

-- At the instant of the "splat", it's falling at 89 m/s.

-- The mass doesn't matter. If not for air resistance, every object
    would fall at the same rate.  The answer is the same for a feather,

Given the scope of Kayla’s education, training, and years of experience as a CMA, would this “favor” fall within the AAMA guidel
Cerrena [4.2K]

Based on the information given, it can be inferred that the favor doesn't fall within the AAMA guidelines of her responsibilities.

From the information given, it should be noted that the guidelines of CMA as stipulated under the American Association of Medical Assistant prohibits the CMA from interpreting the medical data of the patient. Therefore, the favor that was asked by Dr. Hsu of Kayla is simply against the guidelines.

Even though the favor that was asked by Dr. Hsu was prohibited by AAMA, it should be noted that the final part of the favor about faxing the report to the internist would fall within AAMA guidelines.

In conclusion, the best way that Kayla can respond to Dr. Hsu is to decline doing the favor.
