A photodiode passes 8 A reverse photocurrent when irradiated. Design a simple circuit that uses a single op amp to yield +5 V under this condition and calculate component values.
$\lambda_1$ $\mu_1$ p n1 $\lambda$ 1-p n2 $\lambda_2$ $\mu_2$ $\mu$ Consider a network shown in Figure above. A Poisson stream of packets has arrival rate $\lambda$ packets/sec and exponentially distributed packet lengths of average value L bits. The network can send these packets along two different routes to their common destination. Each route consists of one node, that is, of one buffer equipped with a transmitter. The two nodes use transmitters with different rates. Consequently, the two nodes 1 and 2 are modeled as queues with exponential service times with different rates. For each node $j$ ($j$=1,2), $\lambda_j$ designates the average rate of packets going through the node. Packets are sent to node 1 with probability $p$ independently of one another and to node 2 otherwise, $\mu_j$ is the average service rate of that node (Assume $\mu_j$ is Poisson and $\mu_1$, $\mu_2$ $\mu$ packets/sec. Both nodes have infinite queues). a. Find the average delay per packet on each route. Sketch a curve showing average packet delay versus p. b. Find the value of p that minimizes the average delay per packet in the network in terms of given system parameters. c. Find the value of p that provides the same average delay on each route in terms of given system parameters.
Question The molar mass of a gas is equal to: Select the correct answer below: $\frac{mRT}{PV}$ $\frac{RT}{mPV}$ $\frac{PV}{mRT}$ $\frac{PR}{mVT}$
l- A bead slides without friction on a loop-the-loop track (see Fig.). If the bead is released from a height h = 30, what is its speed at point A? How large is the normal force on it if its mass is 500 g? (R = 10 cm; g = 10 m/s^2) 2- A mass m is attached to a spring which is held stretched a distance x by a force F (see Figure), and then released. The spring compresses, pulling the mass. Assuming there is no friction, determine the speed of the mass m when the spring returns: (a) to its normal length (x = 0; b) to half its original extension x/2.
(10 pts) 8. Evaluate $\int \frac{\sqrt{x^2 - 1}}{x} dx$ \newline Hint: Apply the substitution $x = sec(\theta)$. This will require using trig identities to simplify.
6. Molasses is too big on a molecular level to diffuse through the tubing membrane into the beaker. But, let's say we used a different type of tubing that molasses could fit through. What do you think would have happened? Would molasses have moved into the beaker? Would water have moved into the tube? Explain your answer (2 points). 7. Over time, the solution in the thistle tube would have eventually stopped rising. Explain why this happens. (2 points)
