What is the boiling point of water in SI units?
~373 K
100
What is the SI unit for charge? It must be spelled correctly.
Coulomb
(or Coulombs)
100
In order to avoid affecting the current of a circuit, a voltmeter must have a very _____ resistance.
high
100
Are these bar magnets attracted to each other or repelled?
They're repelled by each other.
100
Sound waves are an example of a ________ wave that propagates through the air.
longitudinal
125
In order to get the most work out of a gas, an __________ process should happen first, then an __________ process.
Isobaric; Isovolumetric (Isochoric)
This makes the area under the PV graph as large as possible, since W = -PΔV. The terms "constant pressure" and "constant volume" are acceptable.
125
The units N*m/C, when simplified, give us the units for ___________.
Voltage (V)
(or, Electric Potential)
125
Two capacitors have capacitances of 2.00 µF and 0.50 µF. Determine the equivalent capacitance if they are connected in series.
0.40 µF

A conducting wire is placed in a magnetic field directed out of the page. Which direction would the current need to move to deflect the wire to the right?
Up (toward the top of the screen)

A raft of mass 180 kg carries two swimmers of mass 50 kg and 80 kg. The raft is initially floating at rest. The two swimmers simultaneously dive off opposite ends of the raft, each with a horizontal velocity of 3 m/s. With what velocity and in what direction does the raft start to move?
0.5 m/s, towards the 50 kg swimmer
150
Which Law states that two systems in equilibrium with a third system are in thermal equilibrium with each other?
Zeroeth Law of Thermodynamics
150
What is the value of Coulomb's constant?
8.99 x 10^9
150
Three resistors have resistances of 2.00 Ω, 10.0 Ω, and 25.0 Ω. What's the equivalent resistance when they are connected in parallel?
1.56 Ω
150
A hanging Slinky toy is attached to a powerful battery and switch. When the switch is closed so that the toy now carries current, what happens to the Slinky?
The Slinky compresses (each coil becomes a magnet that is oriented the same direction, so every coil attracts the others)
150
A 5 kg box slides down a frictionless 30o inclined ramp. Assuming g = 10 m/s2, what is the acceleration of the box?
5 m/s2
175
The type of thermodynamic process that has no transfer of heat.
Adiabatic
175
A conducting sphere with a radius of 3 m has a charge of 4 C. What is the strength of the electric field 2 m away from the center of the sphere?
E = 0 N/C
(The electric field is zero inside a conductor)
175
Find the equivalent capacitance of the circuit below:
8 μF
175
Johnny has a permanent magnet, and decides to heat the magnet, strike it with a hammer, drop it on the floor, then cool the magnet. Which of these actions likely caused the magnet to lose strength?
heating it, striking it, and dropping it
(cooling it lowers the average KE of the domains, making them less likely to rearrange)
175
What is the angular speed of a carousel that experiences π/2 rad/s2 of angular acceleration from rest for 2 seconds?
π rad/s
(w = w0+αt)
200
What is the value of the universal gas constant?
8.31 J/(mol*K)
200
How much electric potential energy is given to an electron by a 1 V battery? Include units.
1.602 x 10^-19 J
(or, 1 eV)
200
Two resistors connected in series have an equivalent resistance of 690 Ω. When they are connected in parallel, their equivalent resistance is 150 Ω. Find the resistance of each resistor.
470 Ω and 220 Ω

A 2 T magnetic field is applied to 5 m of a wire that carries 2 A. At what angle is the wire with the field if the force on the field is 10 N?
30° (or 150°)

Johnny holds a 2 kg box on top of a spring, uncompressed, then carefully lowers the box so the spring compresses 0.5 m. What is the change in energy of the Earth-spring-box system? Assume k = 500 N/m and g = 10 m/s2.
5 J
(12.5 J of elastic potential energy was given to the spring, and 7.5 J of gravitational potential energy was lost by the box)
