Astudent has a sample of a mineral that is too big to fit in a graduated cylinder. the density of the sample is known. how can the student determine the volume of the sample?

The formula for density is given as:

density = mass / volume

So given the density and the mass, we can get the volume. The mass can simply be measured using a weighing scale therefore the student can now determine the volume by rearranging the formula:

volume = mass / density

yea hi

explanation:

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
