Explanation:
It is given that,
Height of the building, h = 245 ft
The base of the building and shadow is x.
Let is the angle of elevation that is formed by lines from the top and bottom of the building to the tip of the shadow. Using the trigonometric ratio as :
When x = 300 feet
So, the rate of change of the angle of elevation is -0.001633 rad/ft. Hence, this is the required solution.
Answer:
Zero
Explanation:
Momentum is the product of mass and velocity.
momentum = mv
For a system at rest, the velocity = 0
momentum = m*0
= 0
Even though the individual molecules in a system have some momentum, the system has no momentum because the system is at rest and is left standing.
Answer:
The stirring allows fresh solvent molecules to continually be in contact with the solute. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for the additional solute to dissolve.
