Lenz's Law: The polarity of the induced emf is such that it produces a current whose magnetic field opposes the change in magnetic flux through the loop.
Answer with Explanation:
We are given that
Diameter=0.030 m
Length of sprue==0.200 m
Metal volume flow rate,Q=0.03
Q= because 1 minute=60 seconds
Let 1 for the top and 2 for the bottom
Pressure at the top and bottom of the sprue is atmospheric
Substitute the values
Reynolds number=
Substitute the values then we get
Reynolds number=
Reynolds number=42525
The Reynolds number is greater than 4000 .Therefore, the flow is turbulent.
Acceleration = 14/4 = ....
<span>There are various examples of land features formed by river erosion. One of them is Delta. A delta is formed when sediments are deposited in a place where a river flow into an ocean or lake and build up a land form. Thus, a river delta is a land form that occurs as a result of deposition of sediments carried by a river as the flow leaves its mouth and enter a slow moving or stagnant water.</span>
The answer to this question is distance.
