Chemistry
The former is dissolved in the later, creating a solution.
Distance divided by time is this.
This is a push or a pull.
What is a force?
This is a disturbance in matter that transfers energy through the matter, as in a wave on the water.
What is mechanical wave?
Cosmic rays bombard the earth all the time; this protects us from these cosmic rays.
What is the magnetic field?
The mass divided by its volume is this.
What is density?
If the distance divided by time also has a direction, it is called this.
What is velocity?
This is mass x acceleration due to gravity.
What is weight?
A wave in which the medium vibrates perpendicular to the direction the wave travels, often found in light waves.
What is a transverse wave?
These are the 3 types of rocks on earth.
What is sedimentary, igneous, and metamorphic rocks?
What is a physical reaction and a chemical reaction?
Must be in this order or explain which one is which!
The change of an object's velocity over time is this.
What is acceleration?
This is a force that stops motion.
What is friction?
This ave vibrates the medium parallel to the direction the wave moves, found in sound waves.
What is a longitudinal wave?
1) this is the water evaporated from plants
2) this is the water that falls from the sky to the earth
3) this is the water that comes off the side of a mountain or hill.
What is:
1) transpiration
2) precipitation
3) surface runoff
This is the number on the periodic table that is also the number of protons and electrons of a stable element.
What is the atomic number?
This one word can sum up Newton's 1st Law of Motion.
What is inertia?
This opposes motion while an object is stationary, while this opposes motion while the object is moving.
What is static friction (stationary) and kinetic (moving) friction?
In a sound wave, if an object is moving toward or away from you while making sound (like an ambulance), the frequency changes, changing how we hear the sound; this is what it is called.
What is the Doppler effect?
This is when sediment is moved, changing the landscape.
What is erosion?
This type of bonding is done by metals and non-metals, while this type of bonding is done by non-metals.
What is and ionic bond and a covalent bond?
These are Newton's 3 Laws of Motion.
What is:
1) an object in motion stays in motion unless a force stops it;
2) F=MxA
3) For every action, there is an =, an opposite reaction
This is the measurement of kg x meters divided by seconds squared
What is a Newton?
The speed of sound that is faster than the object making the sound is this.
What is supersonic speed?
This element is the main substance found in air; this is the second most abundant element found in air; this is the less than 1% off air.
