A 1,133-W hair dryer is plugged into a household 20-A, 120-V circuit. If a second device is to be plugged into the same circuit, what is its maximum wattage before the breaker trips?

All household circuits are wired in parallel. A 1140-W toaster, a 300-W blender, and a 50-W lamp are plugged into the same outlet. (The three devices are in parallel when plugged into the same outlet.) Assume that this is the standard household 120-V circuit with a 15-A fuse. (a) What current is drawn by each device? Itoaster = A Iblender = A Ilamp A (b) To see if this combination will blow the 15-A fuse, find the total current used when all three appliances are on. Itotal =

A 120 volt household circuit has a 20 amp circuit breaker (maximum). A 600-Watt heater and a 60 ohm light are connected to this source in parallel. How many amps flow through the 600-Watt heater?

You and your friend are moving a 82kg box across the floor at a constant speed.  You are pushing on the crate parallel to the ground with a force of 62N.  Your friend has a rope tied to the box and they are pulling it at an angle of 37° to the ground with a force of 32N. Construct the free body diagram showing the force acting on the crate in order to find the magnitude of friction the floor exerts on the box.

b.You lift the child by using your elbow joint (pivot point). If the child's mass is 27 kg and distance from child to elbow joint is 0.40 m, calculate the torque?C.A ball slides with initial velocity 0.9 m/s on a frictionless surface and collides with another identical ball of mass at rest. The balls stick together after the collision. Calculate the final velocity of the balls?
