Answer:
dV/dt = 9 cubic inches per second
Explanation:
Let the height of the cylinder is h
Diameter of cylinder = height of the cylinder = h
Radius of cylinder, r = h/2
dh/dt = 3 inches /s
Volume of cylinder is given by

put r = h/2 so,

Differentiate both sides with respect to t.

Substitute the values, h = 2 inches, dh/dt = 3 inches / s

dV/dt = 9 cubic inches per second
Thus, the volume of cylinder increases by the rate of 9 cubic inches per second.
Answer:D
Explanation: both variables change in the same direction. An increase in one variable leads to an increase in the other, a decrease in one lead to a decrease the another
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:
Force is a push or pull action between objects. Pressure is force acting on a surface area of an object, thus it is force per unit area.
