Expert Solution & Answer
To determine
The major difference between medical diagnostic uses of radiation and medical therapeutic uses, in terms of radiation dose.
Explanation of Solution
Introduction:
The energy emitted by the sub-atomic particles is termed as radiation. It travels in the form of energy or particles or as energized particle. In the medical diagnostic the use of radiation has been adopted in frequent ways to cure as the both diagnostic tool and therapeutic tool for treating harmful cell of human being which cause cancer.
In some medical diagnostics, the radiations are often used in many ways such as X-rays, Gamma rays and the other forms of ionizing radiation to cure the certain kinds of cancer but in medical therapeutic the radiation has been used to destroy some cells of a body. The use of radiation procedures in diagnosis may contribute a appropriate dose of ionizing radiation in human life but the inherent properties of ionizing energized radiations causes potential harm to a human body. Such high-energized radiations destroy cancer cells and shrink tumors.
Conclusion:
Thus, we can conclude that the medical therapeutic kill the specific and weaken cells of a human body and whereas in the prospective of doctors, the medical diagnostic has been more recommended as it takes very minute radiation dose and dangerous for a human body.

Is it possible for average velocity to be negative?a. Yes, in cases when the net displacement is negative.b. Yes, if the body keeps changing its direction during motion.c. No, average velocity describes only magnitude and not the direction of motion.d. No, average velocity describes only the magnitude in the positive direction of motion.
Tutorial Exercise
An air-filled spherical capacitor is constructed with an inner-shell radius of 6.95 cm and an outer-shell radius of 14.5 cm.
(a) Calculate the capacitance of the device.
(b) What potential difference between the spheres results in a 4.00-μC charge on the capacitor?
Part 1 of 4 - Conceptualize
Since the separation between the inner and outer shells is much larger than a typical electronic capacitor with separation on the order of 0.1 mm and capacitance in the microfarad range, we expect the
capacitance of this spherical configuration to be on the order of picofarads. The potential difference should be sufficiently low to avoid sparking through the air that separates the shells.
Part 2 of 4 - Categorize
We will calculate the capacitance from the equation for a spherical shell capacitor. We will then calculate the voltage found from Q = CAV.
I need help figuring out how to do part 2 with the information given in part 1 and putting it in to the simulation. ( trying to match the velocity graph from the paper onto the simulation to find the applied force graph) Using this simulation https://phet.colorado.edu/sims/cheerpj/forces-1d/latest/forces-1d.html?simulation=forces-1d.
