Answer:
C
Explanation:
because it's not a volume is mass
1 because the rays are in different directions, which would cause there to be only one intersection.
Answer: 1) Cold water is more dense and will sink in room temperature water.
2) Cold salty water is denser than warm freshwater.
3) Temperature is the measure of heat. Density is the measure of how closely any given entity is packed or it is the ratio of the mass of the entity to its volume.
4) Salinity and density share a positive relationship. As density increases, the amount of salt in water-also known as salinity- increases.
Answer:after -44 degrees it turns into liquid and when it becomes vapor when it gets warmer
Explanation:
Answer:
Energy
Explanation:
The unit is 
.
We can see the formula of kinetic energy is
Where 
is the mass and 
is the velocity of the object.
Which means its unit would be kg times square of meter per second, that is . Which is often referred as Joule.
Also, when look at the formula of work done by an object.
Where 
is the force and 
is the distance traveled by the object due to force .
We an see that its unit is kg meter per second squared times meter. That is equivalent to . This is also a type of energy.
So, the unit is the unit of energy.
