Dimensional Analysis
A car accelerates with some acceleration 'a' for some time 't'. Using the following equation, show that the change in velocity should be in meters per second.
Deltav=a*t
frac[m](s^2)*s=frac[m]s
This is the mnemonic to help remember the color spectrum of visible light.
ROYGBIV
This type of wave requires a medium to transport energy.
Mechanical
What is the most abundant gas in Earth's atmosphere?
Nitrogen
This is an object's tendency to float or rise in a fluid when submerged.
Buoyancy
A force 'F' is applied to move an object some unknown distance. Some work 'W' is done to move the object. Show that the distance the object moves is in meters. Hint: N*m = J. Use the following equation:
W=F*d
frac[N*m]N=m
True or false: Light ONLY behaves as a particle.
False. Light can behave as both a particle and a wave.
True or false: Waves cannot transport energy, only matter.
False
Which continent is the Sahara Desert located on?
Africa
This is the specific value for the speed of light
3 x 108 m/s
frac[1]s*m=frac[m]s
This property of visible light is what primarily distinguishes different colors of light.
Different wavelengths. (If you said different energy states you're also right, but that option won't be on the quiz)
These are waves in which the motion of the medium is perpendicular to the direction the waves travel.
Transverse
Which planet has the largest volcano in the solar system, Olympus Mons?
Mars
What is the equation for Pascal's Law?
F_1/A_1=F_2/A_2
A box with some mass 'm' is subject to a net force 'Fnet'. Show that its acceleration should be in units of m/s2. Hint: A Newton is equal to kg*m/s2. Use the following equation:
a=frac[F]m
frac[frac[kg*m](s^2)](kg)=frac[m](s^2)
This is the production of light as a result of high temperature (Ex. A burning candle)
Incandescence
A wave has a speed of 0.036 km/s and has a frequency of 12 Hz. What is its wavelength?
3.0 m
Who is credited with inventing the telephone?
Alexander Graham Bell
Draw a qualitative FBD for an object sinking in a fluid
(See Ms. D's work on the board to the right)
The formula for kinetic energy is as follows, where 'm' is mass and 'v' is velocity. Solve for velocity and show that the final solved equation gives you the S.I. units for velocity. Hint: J = kg*m/s2
KE=frac[1]2m*v^2
sqrtfrac[frac[kg*m^2](s^2)](kg)=sqrtfrac[m^2](s^2)=frac[m]s
Why can light travel through space?
Because it is an electromagnetic wave
This type of wave interference is when two waves are completely out of sync and cancel each other out.
Destructive
What is the sum of the angles in a pentagon?
540 degrees
True or false: For a fully submerged object, the volume of the displaced water is the same as the inverse of the volume of the fully submerged object.
False
