Homework Answers
1. Is the time interval between the R wave and the peak of the pulse wave the same for each subject? Does this time interval differ with the heart rate?
Yes, the time interval is the same. The time interval varies with heart rate because an individual's activity level and relaxation differ according to the time

The peak of the R wave is said to occur at about the same time as the beginning of systole. For each beat of the heart, when does the peak of blood flow in the fingertips occur relative to the peak of the R wave?

a. A 1V peak to peak sine wave with a frequency of 1 kHz is applied across a 5 kΩ resistor. Find an expression for the current through the resistor as a function of time. b. The same input voltage is applied across a single 2 µF capacitor, what is the current through the capacitor as a function of time? c. The frequency of the sine wave is now increased to 5 kHz. How does this affect the current in...

Problem 5: The top picture shows a wave pulse on a string (string 1-blue) travelling to the right, where the string is attached to another string (string 2 - orange). The bottom picture shows the reflected wave some time later. If the tension on both strings is the same, a) [2 points] Is string 2 more or less dense than string 1? Justify your answer b) [3 points) in which string will the wave travel faster? Justify your answer. c)...
