A resistor R = 1 kohm an inductor L = 1 mH and a capacitor C = 1 muFare used in a circuit which is driven by a voltage source v_s(t) = 10 sin(10^5 t + 45degree)(waming: note the input is a sine function not a cosine function.) What is the phasor corresponding to the voltage source? Express it in the polar form AZB and write your answer as "A B" without the quotation marks.

Once the ideas were narrowed down and divided into categories, the group was split into four smaller teams. What phase(s) of the design process was each of these groups responsible for? A. Shopping B. Safety C. Checkout D. Finding stuff you need

A series circuit contains five resistors. The total voltage applied to the circuit is 120 V. Four resistors have voltage drops of 35 V, 28 V, 22 V, and 15 V. What is the voltage drop of the fifth resistor?

Which process does a professional use to determine an object's position relative to the camera? A. Segmentation B. Pose estimation C. Detection D. Tracking E. Egomotion

Consider the following pulley system. A block of mass m is connected to a translational spring of stiffness k through a cable, which passes by a pulley. The pulley rotates about a fixed mass center 0. The moment of inertia of the pulley about its mass center is I_0. Determine the equation of motion using the energy method.

A certain battery has terminals labeled a and b. The battery voltage is vab = 12 V. a) To increase the chemical energy stored in the battery by 900J, how much charge must move through the battery? b) Should electrons move from a to b or from b to a?

The sewage treatment plant consists of a large concrete tank that initially contains 440,000 liters of liquid and 10,000 kg of fine suspended solids. Water is pumped into the tank at a rate of 40,000 liters per hour, and liquid containing solids exits at the same rate. Estimate the concentration of suspended solids in the tank after 5 hours.

Saturated water at 25C enters a tank through a 10-cm diameter pipe at a velocity of 3 m/s. At the bottom of the tank, water exits at 6 m/s through a 5.25- cm diameter pipe. The depth of the water in the tank is 1.5 m. The tank has a diameter of 1.25 m and a height of 2.5 m. Water in the tank is also magically kept at 25C, which is the same to the surrounding temperature. Assume that pressures at inlet, outlet, and the surrounding are roughly the same and pressure effect is negligible.

Which of these formulas is the equivalent of I=E/R?​
