Mateo makes a table of the symbols that represent the parts of an electric circuit.
What label should Mateo plac
Provides electrical energy
Which device provides electrical energy to run an electric circuit?
the battery
Which statements describe a closed circuit? Check all that apply.
Bulbs will shine.
The circuit is complete.
Charges flow.
Roshan describes the basic parts of an electric circuit using a shower as a model. Which part of a circuit does the water pipe represent?
the wire
Which device manages the flow of current in an electric circuit?
the switch
Patty makes a table of the symbols used for the parts of an electric circuit.
What label should Patty place in the marked cell?
Resistor
When an electric circuit operates, a buzzer makes a sound. What happens to the electric charges in this circuit?
The electric charges move from the energy source through the buzzer and back to the energy source.
What does the diagram show?
one battery, two switches, and three light bulbs
How many of each component are shown in the diagram? Check all that apply.
one battery
two switches
two resistors
three light bulbs
What symbol would best represent an electric fan in an electric circuit?
C.)
Chang wants to build a circuit that will light up the bulb from a flashlight. Which component could Chang leave out and still light up the bulb?
the switch
In a movie, a character cuts a wire, which stops the countdown timer of a bomb. What does cutting the wire do to the circuit?
It opens the circuit so that electric charges do not flow to the timer.
What is the main disadvantage of parallel circuits?
They are complicated to design and build.
A large cooler is filled with water, as shown below.
How does the valve on the cooler compare with the switch in an electric circuit?
Closing the valve stops the flow of water, but opening a switch stops the flow of charges.
Which statement describes an open circuit?
The circuit is incomplete and broken, and the lights in the circuit do not shine.

List the three basic types of parking methods.
ENGINEERING
A rigid, insulated container fitted with a paddle wheel contains 4 lb of water, initially at $220^\circ F$ and a quality of 50%. The water is stirred until the temperature is $350^\circ F.$ For the water, determine (a) the work, in Btu, and (b) the amount of entropy produced, in $Btu/^\circ R.$
ENGINEERING
Air enters a compressor operating at steady state at $15 lbf/ in.^2,$ $80^{\circ} \mathrm{F}$ and exits at $400^{\circ} \mathrm{F}.$ Stray heat transfer and kinetic and potential energy effects are negligible. Assuming the ideal gas model for the air, determine the maximum theoretical pressure at the exit, in $lbf/in.^2$
ENGINEERING
A vertical double-pane window consists of two sheets of glass separated by a 1.5-cm air gap at atmospheric pressure. The glass surface temperatures across the air gap are measured to be 278 K and 288 K. If it is estimated that the heat transfer by convection through the enclosure is 1.5 times that by pure conduction and that the rate of heat transfer by radiation through the enclosure is about the same magnitude as the convection, the effective emissivity of the two glass surfaces is(a) 0.47(b) 0.53(c) 0.61(d) 0.65(e) 0.72
