Momentum = (mass) x (speed)
Divide each side by (speed): Mass = (momentum) / speed
Mass = (45,000 kg-m/s) / (30 m/s) =
1,500 kg .
The energy that the student shoud use in order to climb the stairs is equal to its increase in gravitational potential energy:
where m is the mass of the student, g the gravitational acceleration and
the variation of height. Plugging numbers into the equation, we find
The power required for the student to climb the stairs is equal to the work done divided by the time taken:

An illustration of the impact of Frontier justice is the idea that people have the right to use fatal force against others who enter their house.
What is Frontier justice?
- Frontier justice is administrative retribution that is driven by the absence of rule and regulation or discontent with the administration of justice.
- A biased judge can also be described using this Frontier justice.
- Frontier justice is characterized by practices like lynching, vigilantism, and gunfighting.
- Like Frontier justice there is another law, named castle doctrine, also referred to as a castle law or a defense of habitation law, which is a constitutional principle that defines a person's home or any other legally occupied location as a place in which that individual has protections and immunities, allowing one, in certain situations, to use force to safeguard oneself against an attacker, free from criminal action for the consequences.

Answer:
<em>liquid turns into vapor when the liquid molecules achieves the energy to break down the form or when gets highly excited. The temp required for this is called latent heat of vaporization. As the liquid molecules attain this energy through heat it suddenly changes form into vapor , and when the heat is continued , molecule after molecule receives this energy and changes to vapor .So if you continue heating the liquid all the liquid will change form to vapor state leaving residue , ie the dissolved particles .</em>
