Doubly‑charged calcium ions, Ca 2 + , are released into your bloodstream and flow through your capillaries. The diameter of a capillary is about 8.90 μm, calcium ion concentrations are approximately 1.10 mol/m 3 , and typical electric current flow due to the Ca 2 + ions is around 1.2 nA. Calculate the drift speed v drift of the calcium ions. v drift = m/s

A girl swims the length of a pool and back in 29.4 s. The pool is 21.5 m long, and the girl's speed is constant. (a) Compute her speed v and her average velocity v bar. speed average velocity (b) When is her acceleration not equal to zero? when she reaches the middle of the pool when she is turning around at the end of the pool when she is about to reach the end of the pool

Using real world examples, compare and contrast the the characteristics of a perfect competitive firm, when a perfect competition firm produces v. shut down, stays in business v. go out of business, and the relationship between economic profit, normal profit, and accounting profit in these decisions. Use comprehensive definitions, real world examples, and comprehensive applications in your answer.

2. In an experiment on a two-port network, the following observations are recorded:

V1 = 25 mV and I2 = 5 mA with port 1 open-circuited and V2 = 10 V

I1 = 10 mA and I2 = 1 A with port 2 short-circuited and V1 = 20 V

1. Obtain the Z-parameter of the two-port network.

2. Based on part Q2(b)(i), determine whether the network is reciprocal or otherwise.

A low voltage digital device has a low state of 0 V and a high state of
1.8 V. It generates a signal train of high pulses at a rate of 1 MHz, these
pulses having a 10 ns width and transition times of 100 ps.
(a) Plot the upper bound of its harmonic components up to 10 GHz.
(b) Determine the amplitudes of the third and 101st harmonics.
(c) Determine the signal bandwidth.

Consider the titration of 50.0 mL of 0.0500 M Cu+ with 0.1000 M Fe3+ to give Cu2+ and Fe2+ using Pt and standard H+/H2 reference electrode to find the end point. The standard electrode potentials are E0Cu+/Cu2+=0.161 V and E0Fe2+/Fe3+=0.767 V. Calculate the actual electrode potential, E, at the following volumes of Cu2+ (i) 15, (ii) 25, and (iii) 26 mL

We can use breadth-first search to find the length of longest simple path in the BFS tree
starting at s by the simple method of checking each v.d value at the end of the algorithm. BFS is
Θ(|V | + |E| and this adds only Θ(|V |) work.
Find an even easier approach that adds only constant time (Θ(1)) work via a simple modification to
the BFS algorithm.

Two financial assets with gross return (R1, R2) are jointly normally distributed. E(R1) = 1.06 and E(R2) = 1.12. V ar(R1) = 0.03, V ar(R2) = 0.04, and Cov(R1, R2) = 0.025. Draw the mean-variance frontier formed by the two assets. Mark the minimum variance. Notice that the mean of portfolio formed by these two assets falls in the interval of [1.06, 1.12].

A survey of 600 high school students in our stat showed that 216 felt unsafe in their local school. Construct a 95% confidence interval for the proportion of students who felt unsafe.
