Concept explainers
Biomechanical engineers have developed micromechanical devices for measuring blood flow as an alternative to dye injection following angioplasty to remove arterial plaque. One experimental device consists of a 300-μm-diameter, 2.0-μm-thick silicon rotor inserted into blood vessels. Moving blood spins the rotor, whose rotation rate provides a measure of blood flow. This device exhibited an 800-rpm rotation rate in tests with water flows at several m/s. Treating the rotor as a disk, what was its

In the same game the king has a statue made that is 9.00 Bloits high. What is this in meters?arrow_forwardNo chatgpt pls will upvotearrow_forward

- Make a plot of the acceleration of a ball that is thrown upward at 20 m/s subject to gravitation alone (no drag). Assume upward is the +y direction (and downward negative y).arrow_forwardLab Assignment #3 Vectors 2. Determine the magnitude and sense of the forces in cables A and B. 30° 30° 300KN 3.

- Three point-like charges are placed at the corners of an equilateral triangle as shown in the figure. Each side of the triangle has a length of 20.0 cm, and the point (A) is located half way between q1 and q2 along the side. Find the magnitude of the electric field at point (A). Let q1=-1.30 µC, q2=-4.20µC, and q3= +4.30 µC. __________________ N/Carrow_forwardNo chatgpt pls will upvotearrow_forwardNo chatgpt plsarrow_forward
