Answer:
Explanation:
We know that the tangent function relates the angle of the right triangle that forms the hot air balloon rising:
Differentiating (1) with respect to time, we get:
since x is a constant value. Replacing:
Answer:
Temperature is the kinetic energy of the particles of a substance.
Explanation:
The more kinetic energy a particle has the higher it's temperature. In the case of the atmosphere, which is what we are primarily concerned with in Meteorology, we measure this using a mercury thermometer (in certain situations we use an alcohol thermometer and of course modern times have given us things like dewcells and digital thermometers but we always go back to the mercury thermometer for accuracy).
Once it leaves the bat, the club, or the hand, there is no
horizontal force on it (ignoring air resistance). So it has
no horizontal acceleration (ignoring air resistance).

Answer:
6.93m
Explanation:
Using the method of SOH CAH TOA
The base of the tree is 12m which is the adjacent side of the triangle to be generated, the height of the tree will be facing the angle of elevation and it is the opposite side.
Using the formula tan(theta) = Opposite/Adjacent
Given theta = 30°
Adjacent is 12m which is the distance the tree is making with the shadow on the ground
Opposite side will be the height of the tree.
Tan(theta) = height/12
Tan30° = height/12
Height = 12tan30°
Height = 6.93m
Therefore the height of the tree is 6.93m
