speed of a wave = frequency x wavelength
What is the universal wave equation?
100
This guy defined 3 main laws of Physics and is celebrated for our classical understanding of gravity.
Who is Sir Isaac Newton?
100
This type of energy is stored by moving a mass away from another large mass.
What is gravitational potential energy?
100
This is the unit for charge.
What is a Coulomb?
100
We use this hand for rules related to electron flow.
What is left?
200
This occurs in a closed air column when the length of the column is equal to 5/4 of the wavelength.
What is the third resonant length?
200
This unit is equivalent to a kg m/s^2.
What is a Newton (N)?
200
This is equal to the change in kinetic energy of an object (assuming no other changes in energy) and is a product of applied force and displacement of an object.
What is work?
200
This refers to how much charge flows past a point in a particular amount of time.
What is current?
200
A magnetic field will induce current to flow as long as the magnetic field that is produced will do this to the field that is inducing it.
What is oppose?
300
This beat frequency will be heard when a 204 Hz fork is sounded with a 200 Hz fork.
What is 4 Hz?
300
A 100 kg object will accelerate at this rate if a 25 N force is applied to it.
What is 0.25 m/s^2?
300
This is the resulting factor increase to an object's kinetic energy if its speed is doubled.
What is 4? (quadroupled)
300
This is an equivalent unit for J/C.
What is a Volt?
300
A magnetic field will be produced in this direction when a straight conductor is carrying current into a page.
What is clockwise?
400
As a moving source approaches an observer, she will hear the frequency as this because of the Doppler effect.
What is higher?
400
This is what causes someone to feel as though they're pushed to the outside of a car when it goes around a corner.
What is inertia?
400
This is absorbed or given off as a product of an object's mass, specific heat capacity, and temperature change.
What is thermal energy?
400
This is the amount of energy in J when a 10 A current passes across a 10 V potential difference in 1 s.
What is 100 J?
400
This is Mr. Lenz's first name.
What is Heinrich?
500
This is the speed of sound in air when the temperature of the air is 0 degrees Celsius.
What is 332 m/s?
500
This type of force acts from the outside of a rope towards the centre.
What is tension?
500
This is a unit equivalent to 3.6 MJ.
What is a kWh?
500
This is the equivalent resistance when four 2-ohm resistors are connected in series.
What is 8 ohms?
500
This principle allows a traffic light circuit to change when it senses that a car has stopped (because it changes the magnetic field in the region of a conductor).
What is electromagnetic induction?
