Answer:
m/min
Explanation:
You have to use the volume of a cone, which is:
![V=\frac{1}{3}\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7Dh)
where r is the radius of the base and h is the height.
In this case, r=5 and h=10. The radius can be written as r=h/2
Replacing it in the equation:
(I)
The rate of the volume is the derivate of volume respect time, therefore you have to perform the implicit differentiation of the previous equation and equal the result to 3.14 m³/min
![\frac{dV}{dt}=\frac{\pi }{12}(3)h^{2}\frac{dh}{dt} =\frac{\pi }{4}h^{2}\frac{dh}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7BdV%7D%7Bdt%7D%3D%5Cfrac%7B%5Cpi%20%7D%7B12%7D%283%29h%5E%7B2%7D%5Cfrac%7Bdh%7D%7Bdt%7D%20%3D%5Cfrac%7B%5Cpi%20%7D%7B4%7Dh%5E%7B2%7D%5Cfrac%7Bdh%7D%7Bdt%7D)
Replacing dV/dt= 3.14, h=7.5 and solving for dh/dt, which represents how fast the level is rising:
![3.14=\frac{\pi }{4}(7.5)^{2}\frac{dh}{dt}\\3.14=\frac{225\pi }{16}\frac{dh}{dt}](https://tex.z-dn.net/?f=3.14%3D%5Cfrac%7B%5Cpi%20%7D%7B4%7D%287.5%29%5E%7B2%7D%5Cfrac%7Bdh%7D%7Bdt%7D%5C%5C3.14%3D%5Cfrac%7B225%5Cpi%20%7D%7B16%7D%5Cfrac%7Bdh%7D%7Bdt%7D)
Multiplying by 16/225π both sides:
m/min

Answer:
Mechanical energy is the ordered movement of the molecules as a single unit, while Thermal energy is the random movement of the molecules. Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy.
Answer:
Inertia is the reason that people in cars need to wear seat belts. Instead, the riders continue moving forward with most of their original speed because of their inertia. If the driver is wearing a seat belt, the seat belt rather than the windshield applies the unbalanced force that stops the driver's forward motion.
