A

for every action theres an equal and opposite reaction

18
Q

atomic mass

A

A

electrons

20
Q

key trait of a sound wave

A

crest, trough, wave length, amplitue, rest line

21
Q

energy conversions during a H20 balloon slingshot

A

The balloon slingshot is mechanical energy, when the balloon is in the pouch and being pulled back it is potential energy. It is then converted into kinetic energy when it is soaring in the air.

22
Q

plant adaptation

A

flowers become more bright to attract pollinators

23
Q

chemical properties and changes

A

A chemical property is how a substance reacts with something else. A chemical change is a change in the physical and chemical properties

24
Q

How do u find the average speed?

A

Distance traveled divided by the time it took

25
Q

What are some examples of chemical properties?

A

flammable objects, and oxidation
