B. Exploring the Lesson 1. A kitchen circuit wired to 200 V is protected by a 12-A fuse. Can a 1 000 –W Oven , 11 00-W Stove, and 400-W rice cooker be used simultaneously?

2. Five identical cells of 10.0 V each are connected in series. What is the total voltage? Suppose you connect two cells parallel to each other and then connect this parallel combination in series with the remaining cell. What is now the total voltage?

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
