Draw a picture labeling the poles of a permanent magnet that has been cut in half

What pole of the compass needle points north?

Which of the following is NOT a way to increase the strength of an electromagnet:

a) Increase the current through the electromagnet

b) Switch the direction of the current through the electromagnet

c) Place an iron core inside the electromagnet

d) Increase the number of coils of wire in the electromagnet

Would you describe a refrigerator door as 

a) magnetic

b) acting as a permanent magnet

c) having magnetic declination

d) being an electromagnet

e) capable of electromagnetic induction

What two electromagnetic devices have symmetry, in that electrical energy is either used or produced through the process of electromagnetic induction.

This is the only type of electrical power generation that we studied with no turbine

Instead of burning material that has been around for thousands or millions of  years, most forms of this energy burn other things to heat up water to steam, which drives a turbine

A specific isotope of Uranium is used in most of these electrical power plants which produces no greenhouse gases

In 2007, about 70% of the electrical energy produced came from this source

Using the gravitational potential energy generated by the hydrologic cycle, there is very little maintenance required for these power plants.

Label the Wavelength of a transverse wave from trough to trough

Draw the fourth harmonic of a vibrating string (standing wave)

What principle states that when a sound source is moving away from an observer it will have a lower frequency and sound lower in pitch?

What is the frequency of a sound wave which has a speed of 334 m/sec and a wavelength of 56 cm? Answer in correct sig figs with standard SI unit! 

A photon of light can be described as having duality of which two properties?

Orange light has a frequency of 500 THz. Express this value in Hertz, using scientific notation.

Compared to green light, violet light has a(n) ___________ frequency, a(n) ___________ wavelength, has  ___________ energy, and moves at a(n) ____________ speed.

A red shirt appears red because

a) it absorbs red light

b) it reflects red light

c) it emits red light

d) it reflects white light, which stimulates red cones in the eye

a) gamma rays

b) ultraviolet 

c) x-rays

d) visible light

e) radio waves

A pendulum has a string length of 75 cm, a mass of 4.5 kg, and a release angle of 23.8 degrees. How many full swings will the pendulum complete before you hear thunder if lightning flashes 4.8 miles away?
