<span>Boyle's Law, in short, states that the volume of a gas is inversely proportional to its pressure AS LONG AS THE TEMPERATURE REMAINS UNCHAnged </span>
Im not sure if this is physics or mathematics. but if 300 msec then per minute this will equal to 300 X 60 sec =18000 m per minute
<u>Explanation:</u>
- Victor pretends he can speak French > Rising action.
- Victor gets his school schedule > Exposition.
- Victor tries to get Teresa's attention after homeroom and at lunch > Rising action.
- Teresa asks Victor if he will help her in French > Falling action.
- Victor checks out books to learn French and help Teresa > Climax
The air mass that originates over land in Canada is most likely to be cold and dry
<u>Explanation:</u>
- The air masses overland from a continent is usually Dry. The air masses are formed by the uneven warming and cooling of the surface of the earth by the sun gives rise to air masses.
- Canada is affected by the five air masses they are Continental Arctic, Maritime Arctic, Maritime polar, Maritime tropical, and Continental Tropic.
- As Canada is most likely affected by the Continental Arctic the air masses are cold and dry.
Answer:
v = 4.4 m / s
Explanation:
Unfortunately, the exercise scheme does not appear. Let's analyze the problem the marble leaves point A with an initial velocity, goes down and then rises to a given height where its velocity is zero, in the whole trajectory they tell us that the resistance is zero, so we can use the conservation relations of the enegy.
Starting point. Point A
Em₀ = K + U = ½ m v2 + mg y_a
point B.
Em_f = U = m g y
the energy is conserved
Em₀ = Em_f
½ m v² + mg y_a = m g y
½ m v² = m g (y -y_a)
v = 
In the exercise the diagram is not seen, but the height of point A must be known, suppose that y_a = 4 m
v = 
v = 4.4 m / s
