<span>To calculate the magnitude of the initial momentum of the car in this situation you have to multiple the mass of the blue car times the speed. The mass, 468kg, times the speed, 21 m/s, equals 9828. This means the magnitude of the initial momentum of the blue car in the situation is 9828kg per m/s. In this case, and in simple terminology, the magnitude measures how big something is. So the magnitude of the momentum is just the measurement of how big the initial moment of the car is.</span>

Answer:
(b) Water
Explanation:
The density of the liquid is found by dividing its mass by its volume.
__
<h3>mass</h3>
The mass of the liquid is the difference in mass between the full and empty graduated cylinder:
liquid mass = (145 g) -(45 g) = 100 g
<h3>volume</h3>
The cylinder is said to contain 100 mL of the liquid, so that is the volume of interest.
<h3>density</h3>
The ratio of mass to volume is the liquid's density:
ρ = (100 g)/(100 mL) = 1 g/mL
This density identifies the most likely liquid as water.
