Answer:
Density relates a mass to its volume.
Density varies with temperature
Density determines if a substance floats or sinks.
Density may have units of grams per milliliter (g/mL)
Explanation:
Density is a characteristic property of a substance or material and is defined as the relationship between the mass of a body or substance and the volume it occupies:
This means the density is inversely proportional to the volume.
On the other hand, density is a scalar quantity and according to the International System of Units its unit is
, although it can be also expressed in .
It should be noted that the density of a body is related to its buoyancy, a substance or body will float on another fluid if its density is lower. In addition, if the pressure of the substance remains constant, as the temperature increases, the density decreases; this means density varies with the temperature as well.
I think its between b or c
Answer:
can you post the full question plz
Explanation:
The _____ with less density will sink and the higher density ____ will rise
Mass of base ball = 0.25kg
Time = t = 0.0075/s
Force = F = 18,500N
Impulse = J = ?
Formula = Impulse = Force x time
= 18,500x0.0075
= 138.75 N-S
Rounded: 140 kg
