The work done is equal to the change in potential energy which is:
P.E = mgh
P.E = 500 x 9.81 x 15
P.E = 73,575 J
Power = work / time
Power = 73,575 / 20
Power = 3,700 Watts
Answer:
Constructed cladograms all typically share certain key features: Root – The initial ancestor common to all organisms within the cladogram (incoming line shows it originates from a larger clade) Nodes – Each node corresponds to a hypothetical common ancestor that speciated to give rise to two (or more) daughter taxa.
Explanation:
Answer: Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium
Explanation: Hope this helped
Since you are looking at a right fringe, the answer is all
the time a multiple of the wavelength for the reason that the light makes
constructive intrusion. If you are looking at the center (zeroth) fringe, the
difference is (450)(0) = 0. For the first maximum, the difference is 450 nm.
For the second, it is 450 x 2 = 900 nm. Basically, for the nth maxima, the
difference is 450n.
