Most wall sockets in your home at 120V. There are tons of resistors in a home. Based on what you just learned about a 9V battery blowing out an LED bulb , do you think it is important to have resistors in a house?

How do we measure or think of speed in the united states?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
