100

What does a wave always transfer?

Energy

100

Define Refraction

when a wave hits a surface and bends as it passes through the substance.
100

What are the key components of a circuit ?

- battery (power source) 

- conductive wires

- load (light bulb)

- switch 

100

What is a constant ?

Variable(s) that stay the same within the experiment 
100

What is the equation for Ohm's Law?

V=IR

200

What are the two types of waves?

Mechanical & Electromagnetic Waves

200

What property does amplitude impact?

Volume

200

There is a circuit with all the components but the light bulb is not turning on, why do you think ?

- the circuit is open which is not allowing electrons/ electricity to flow through from the battery to the wires and to the load to turn it on. 

200
What is a dependent variable ?
The variable that is measured in the experiment 
200

In Ohm's law equation, what does I stand for?

Current

300
Give 1 example of each type of wave 
Mechanical wave = sound wave 

Electromagnetic wave = light wave 

300

What property does wavelength impact?

Color

300

Current & Resistance have what type of relationship?

Inverse relationship

- when one increases, the other decreases

- when one decreases, the other increases

300

What is an independent variable ?

A variable that is purposefully manipulated/changed in the experiment 

300

Define electric force

When objects interact with each other based on their charge 

400

What are the key components to drawing a wave diagram?

- start at 0 

- scale (+/-)

- Dashed line 

- correct amplitude 

- correct frequency

400

What property does frequency impact?

Pitch

400

Voltage & current have what type of relationship?

Direct relationship

- when one increases, the other increases

- when one decreases, the other decreases

400

The height of bean plants depends on the amount of they receive 

What is the independent variable in this scenario?

The amount of water the plants receive

400

Two protons are coming near one another. What interaction is going to happen? Why?

Repulsion because they are like charges 

500
What is the key difference between a mechanical and electromagnetic wave?

Electromagnetic waves do not require a medium

Mechanical waves do require a medium

500

Define absorption

Occurs when a wave hits a surface and the energy of the wave is taken up by the surface

500

The brightness of lightbulbs on a series circuit will _______ as you increase the number of lightbulbs. 

a. increase

b. decrease

c. remain constant 

decrease

500

An investigation found that more bushels of potatoes were produced when the soil was fertilized more. 

What is the dependent variable?

The amount of bushels that were produced 

500
A proton and a neutron are coming towards each other. What interaction is going to occur? Why?

Nothing is going to happen because neutrons do not have any charge, so neither repulsion or attraction
