The acceleration of any body is the rate of change of velocity of that body. If the motion of the object being considered is plotted on a graph, with the velocity on the y-axis and the time on the x-axis, this ratio will be equivalent to the slope of the graph, not the area above the line.</span>
l will help and if you get it correctly I will say you are welcome
To change of phase from gaseous to liquid.....The amount of energy required to change a unit mass of a subtance from solid to liquid (and vice versa)
Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following:
