Explanation of Solution

Nuclear medicine in different ways uses radioactive isotopes.

One of the most common uses is a tracer in which a radioisotope like technetium-99 m is taken orally or injected into the body or inhaled. The radioisotope then circulates through the body or only some tissues absorb it. Its distribution can be tracked by the radiation it discharges.

Depending on the radioisotope used, the emitted radiation can be captured by various imaging techniques, such as single photon emission computed tomography (SPECT) or positron emission tomography (PET). Physicians can examine the blood flow to certain organs and evaluate the organ function or bone growth through such imaging.

Radioisotope therapeutic applications are typically aimed at destroying the target cells. This approach forms the basis of radiotherapy, which is commonly used to treat cancer and other tissue growth conditions, such as hyperthyroidism.

In medicine, there are many uses of radiation. The most commonly known is that x-rays are used to see if bones are broken. The large area of radiographic use is called radiology. In radiology, we find more specialized areas such as mammography, computerized tomography (CT) and nuclear medicine (the specialty that usually injects radioactive material into the patient). Cardiology is another area of x-ray use, where special x-ray images are taken from the heart.

Two objects get pushed by the same magnitude of force. One object is 10x more massive. How does the rate of change of momentum for the more massive object compare with the less massive one? Please be able to explain why in terms of a quantitative statement found in the chapter.
A box is dropped on a level conveyor belt that is moving at 4.5 m/s in the +x direction in a shipping facility.  The box/belt friction coefficient is 0.15.  For what duration will the box slide on the belt?  In which direction does the friction force act on the box?  How far will the box have moved horizontally by the time it stops sliding along the belt?
