2. You want to turn on the current through an inductor (inductance = L) in a controlled manner, so you place it in series with a resistor R = 2200 Ω, a switch, and a dc voltage source V0 = 240 V. After closing the switch, you find that the current through the coil builds up to its steady-state value with a time constant τ. You are pleased with the current’s steady-state value, but want τ to be half as...

Imagine that you have two pieces of different types of metal of the same mass. You then perform the following experiment. You take 500 ml of water in a well-insulated beaker with a diameter of 75 mm at 20.0+/-0.05°C. The two masses are heated to 100 +/- 0.05°C. Metal A is place in the water container. After waiting some time, you find that the temperature of the system stabilizes at 24.8+/- 0.05 °C. You then add metal B to the...

(1.) Sample Lab-Based Question... In the physics laboratory you are given a metal block that is approximately the size of a brick. You are also given 2.0m long wood plank with a pulley* attached to the end of it. Your objective is to experimentally determine the coefficient of kinetic friction ( μ k ), between the metal block and wood plank. *Note: you do not necessarilly need to use the pulley. (a.) From the list below, select the additional equipment...

When you jump, you start by crouching down a bit, which lowers your center of mass to a distance d ≈ 40 cm below where it normally is. You then exert a downward contact force on the ground equal to about 2.5 times your weight (mg); we may assume that this force is constant while it acts. After your center of mass rises past its usual location, you leave the ground with an initial velocity v, and you reach a...

QUESTION 1. A ferris wheel has a radius of 12 m. The center of the ferris wheel is 14 m above the ground. When it is rotating at full speed the ferris wheel takes 10 s to make a full turn. We can track one seat on the ferris wheel. Let’s define t = 0 to be a time when that seat is at the top of the ferris wheel while the ferris wheel is rotating at full speed. (a)...
