Beth has built a simple series circuit using wire, a battery, a lightbulb, and a switch. the bulb, however, does not light up when the switch is closed.

which describes a step that will troubleshoot and work toward the solution of this problem?

a.
reverse the way the wire is connected to the poles of the battery.

b.
use an electrical meter to test the voltage of the battery.

c.
shorten the length of wire between the battery and the switch.

d.
change the wiring scheme to parallel.

What are the applications of electromagnetic waves

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
