For a given mass, its acceleration is proportional to the unbalanced force acting on it.
What does F = ma mean in words?
100
Heat transfer in solids.
What is conduction?
100

How could you calculate a moment?
200
As water is heated it becomes less dense and rises. Further away from the heat source it cools, becomes more dense and sinks.
What is a convection current?
200
A lens that is thicker in the middle and thinner at the edges.
What is a convex/converging lens?
200

Focal length

The distance between the focal point and the center of the lens

Beneath the elastic limit, extension is proportional to the applied load.
What is Hooke's law?
300

What is measured in J/kgC? What is the amount of heat energy needed to increase the mass of 1kg of a substance by 1 degree celcius?
300
It has shortest wavelength and highest frequency.
Where would you find gamma waves on the electromagnetic spectrum?
300

300

The spectrum of electromagnetic waves with the highest frequency

gamma rays

400
Newton's first law.
Which law states "if the forces on an object are balanced, if at rest it will remain at rest, or if in motion it will move at a constant speed in a straight line"?
400
Reduce humidity, increase temperature, blow across the surface.
In what three ways could you increase the rate of evaporation?
