B because was the idea that Americans were made to civilize the American territory. That ideia was created by God, i mean, the destiny of america was chosen by god.
That's true.
If the line is perpendicular to the y-axis, then it's horizontal,
and parallel to the x-axis.
Every point on the line has the same y-coordinate. If the point (-5, 1)
is on the line, then all the points (any number, 1) are also on it.
The equation of the line is
[ y = 1 ] .
Answer:
Explanation:
Since 100C is the boiling temperature for water, for this problem we don't need to calculate the energy needed to get to the boiling point, just the heat or energy needed to vaporize the water to steam at 100C.
The formula for this is q=m(delta)
q is Joules of heat needed to vaporize the water to steam at 100C
m is mass in grams
Delta is in Joules per gram and can be looked up for water at this temperature. Here, it is approximately 2260J/g. This online lecture should help ease understanding: https://cabrillo.instructure.com/courses/10267/modules/items/256219
Therefore...
q=2.5g (2260J/g)= 5650J = 5.65kJ
I do not do Physics tutoring but am happy to answer questions here.
Velocity is a function of time and defined by both a magnitude and a direction. Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity. Using the information given in a problem, you can determine the proper equation to use and easily answer your question.
