9:26 Х Student Portal 1. A satisfactory radiograph is obtained using 10 mAs at an SID of 40". If the technologist were to repeat the exposure at a new SID of 72", what mAs value would be required to maintain radiographic exposure? 2. If a radiographic image is obtained at 40" using 32 mAs, and a repeat exposure would be performed at an ID of 80", what mAs would be required to produce an image demonstrating similar exposure? 3....

10. (1 pt.) When measuring bond lengths using these models you needed to measure from center atom to center atom and not the length of the plastic bond. At first sight this seems silly, since the length of the bond would seem to be the length of the piece of plastic that represents the bond! However, there is a good reason for measuring atom center to atom center. You have not been told this explicitly, it is not in your...

Part C Iron has a density of 7.86 g/cm (1 cm = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.25 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm = 1 mL) before calculating the volume for the piece of...

1.) Part A An investigator places a sample 1.0 cm from a wire carrying a large current; the strength of the magnetic field has a particular value at this point. Later, she must move the sample to a 11.0 cmdistance, but she would like to keep the field the same. By what factor must she increase the current? Part B The small currents in axons corresponding to nerve impulses produce measurable magnetic fields. A typical axon carries a peak current...
