Answer: D = 16m
Explanation: given values: a = 2 m/s2, v = 4 m/s
In this case we have to determine the diameter of the Ferris wheel.
Diameter of circle is given as: D = 2.r.
First we have to find radius of wheel. The best way to find that is using the centripetal acceleration equation: a = v2/r
Plug in values in above equation to find radius: 2 m/s2 = (4 m/s)2/r 2 m/s2 = (16 m2/s2)/r r = (16 m2/s2)/2 m/s2
r = 8.0m
Diameter of Ferris wheel is:
D = 2.r.
D = 2.8m
D = 16m
Answer:
by conduction, or the transfer of energy from matter to adjacent matter by direct contact, without intermixing or flow of any material. by convection, or the transfer of energy by the bulk mixing of clumps of material. In natural convection it is the difference in density of hot and cold fluid which causes the mixing.
The movement of water that has the greatest effect on the growth of producers is <em><u>upwelling</u></em><em><u /></em>.
Upwelling is a rising of a liquid. The reason upwelling is much better for producers is because it is a slow rising in the water level, preventing erosion to the topsoil and still giving the necessary amount of water and nutrients the producers need.
Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if you need any more help with anything :D <span />
Answer:
It is<em> impossible</em> to construct a machine which produces the <em>work output greater than the work input.</em>
Let us consider the II law of thermodynamics.
According to Kelvin Plank's statement any engine/machine does not give hundred percent efficiency. And violating the PMM-II(Perpetual motion of machine II kind), Always some amount of energy transferred to the sink or surroundings.
Therefore
W(ouput) = Q₁-Q₂
There are many reasons to lower the work output, just for an example friction between the mating parts reduces the work output.
