Answer:
The potential energy in the water will be 0.0769 mJ
Explanation:
We know that energy stored in the capacitor due to charge is given by
From the relation we can see that potential energy is inversely proportional to the capacitance
And we also know that capacitance is directly proportional to the dielectric constant
So the new potential energy will be
So the potential energy in the water will be 0.0769 mJ
Answer:
The value is
Explanation:
From the question we are told that
The depth of the mountain is
Generally the velocity of the surface wave is mathematically represented as
=>
=>
Generally using the Froude number is mathematically represented as
Here V is the velocity of the current
Given that the waves do not travel upstream, then the flow of the current is supercritical which means that
=>
=>
Hence the minimum velocity of the current is
This because the velocity of the current is greater velocity of the surface wave , so minimum will be like the lowest possible value of V which is v
Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulate together in mathematically.
It is given Einstein's special theory of relativity.
It is find the Einstein's special theory of relativity explains the perpendicular behavior of moving charges without recourse to invoking the concept of a magnetic field.
<h2>What is Einstein's special theory of
relativity?</h2>
As we know that one charge creates a field and its that field that actually exerts a force on the other charge. Here we it gives the relationship of two fields like electric field and magnetic field and gives the formula for electromagnetic objects.
Special relativity fixes the problem by the points that the magnetic force in one frame of reference easily be an electric force in other and also some of the combination of them in a frame.
Thus, Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulae together in mathematically.

Answer:
time =20s
Explanation:
Average speed = Distance/time
time = Distance / Average speed
Where Distance = 100meters and speed =5m/s
So,
time = 100m/5m/s
time =20s
Answer:
A rotating fan completes 1200 revolutions every minute. Consider the tip of a blade, at a radius of 0.15 m.
