PLEAAASSEEE help me with these! This is all new and all but idek where to start! They're due by the end of today, so if after midnight on 10-29, don't even bother answering them :(

the formula to finding density is mass/volume.

1. the density of the bread is 0.2 g/cm³

2. 1 mL/g

3. to find the mass using density and volume, it's mass = density x volume, so 0.72 grams

you can figure the other answers out by just dividing mass/volume! hope this helps!

here are some helpful formulas, too:

d = m/v  

v = m/d

m = d * v

m= mass

v= volume

d= density

the body's situation won't change the forces are equal opposit and on the same body

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
