Density Measurements Virtual Lab Investigative phenomenon:

A large wooden boat, filled with passengers, floats on the surface of water. For this investigative phenomenon, you will need to determine the densities of an unknown solid and liquid using different methods of measurement to determine if the solid will float on water. Download the lab report and fill in each section for Part I and Part II while you work through the virtual lab below. You will submit your completed lab report.

the ratio of the conjugate base to the acid required to attain the desired ph.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

(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
