A particle is to be placed, in turn, outside four objects, each of mass m: (1) a large uniform
solid sphere, (2) a large uniform spherical shell, (3) a small uniform solid sphere,
and (4) a small uniform shell. In each situation, the distance between the particle and
No, that's not what I meant. Let me pose it again. See, the plane is stationary and it is held above the surface of the earth. However, the Earth is rotating with respect to the stationary plane. So, the Earth will move but the plane will be stationary. So, can we expect an another place after...
Imagine an Aeroplane held above the Earth's surface for 12 hours, having no contact with the surface of the earth. Suppose that the initial location at time t=0 is Asian continent. So after t = 12 hours, can we expect the aeroplane to be in some other continent or will it be in the same location.
Can physicist pursue a career in CFD??
I have completed M.Sc. in Physics with specialization in radio-physics and electronics and working with a nanosemiconductor company as an Engineer-Technical documentation in India. I am interested to pursue a career in computational fluid dynamics and very...
Switch: tests the value of a given variable against a list of case values and when a match is found, a block of statements associated with that case is executed.
If Else: If the test value is true, then the true block statements following the if are executed.
Now, the point is that I feel...
Voltage source with resistor in series = current source with the same resistor in parallel?
Could you please help me understand the explanation behind connecting the resistor in parallel and not in series for transforming the voltage source into the current source?
"For low power transistors (under 1 W), the current gain is typically 100 to 300. High power transistors (over 1 W) usually have current gain of 20 to 100." — Electronic principles by Malvino
I want to understand why the current gain is high for low power transistors and why it is low for...
Well, I don't think light can travel faster than c. Even I had the same question to my professor when I was studying waveguides. There was an equation which could show some situation where light could travel faster than C. But, we all know the basic postulate of relativity.
