1. Consider a parallel circuit as shown in lecture. Given V=12 V, R1 = 987 Ω, R2 = 1,047 Ω, and R3 = 2,383 Ω. As a round number, the total resistance in Ohms (Ω) is.

2. Consider a parallel circuit as shown in lecture. Given V=11.3 V, R1 = 1,004 Ω, R2 = 908 Ω, and R3 = 2,100 Ω. The total resistance in Ohms rounded to the nearest whole number is.?

1. Consider a parallel circuit as shown in lecture. Given V=11.4 V, R1 = 1,176 Ω, R2 = 939 Ω, and R3 = 2,135 Ω. The current (in Amperes) through the second resistor of 939 Ω is; (to 4 decimal places).?

2. Consider a parallel circuit as shown in lecture. Given V=14 V, R1 = 980 Ω, R2 = 800 Ω, and R3 = 2,082 Ω. The current in mA with 2-decimal precision is?

Using a difractometer and an x-ray source having a wavelength of 1.54 A degree one peak is observed for first order reflection from an FCC material when 2theta is 121 degree. What are the indices of this reflection? What is the interplanar distance?

Choose an important question about your project related to the most modern and advanced blood pressure machines invented to address via prototyping and reduce project risk such as” SPECIAL BLOOD PRESSURE MACHINE PRODUCT THAT IS A WIRELESS, REMOTE MONITORING DEVICE THAT CONNECTS TO A SMARTPHONE APP WITH ACCURATE. MEASUREMENTS”. Design a model and show the drawing as a 3d printer and accompanying test(s) that will enable you to answer the question related to the topic above. Construct a (more advanced) prototype and execute tests for it. Be prepared to share your prototype slides and test results in class.

What are the seven different sample sources and how can they be used by a forensic toxicologist (the more common sources). In your own words, explain each sample source by including as much detail as possible about its collection, convenience (or not), what circumstances it’s collected under, as well as the pros and cons. When doing this, imagine you are the forensic toxicologist and you must make a choice between the six samples, and you want to have as much detail about each one as possible to make the best decision. You must also include details about ADME that relate to each of the samples and how they would impact your sample choice.

Sample Source 2:

Sample Source 3:
