A student and enthusiastic programmer. Love learning Physics! And I make android apps as a hobby.

This will make a great and interesting site : Puzzling. Please follow it

comment Where is the “event horizon” on a basketball hoop?
@fibonatic, nice one there! You could do the same with a basketball in a single bounce off the rim, but as I said, it will require a high enough rotational speed

comment Travel time for accelerating object
@Joshua , the area of trapezoid wont be a simple function but a combination of different functions in different ranges. In the end you will end up following the same procedure described above, which is a perfectly acceptable way to solve such problems

comment Optimal slit width in Young's double slit experiment
How far apart were the pinholes/slits ? and what equipment did you use to make them, what kind of film etc.? Also could you post pictures, although that's not really necessary

comment Why can two (or more) electric field lines never cross?
If I had a penny for every time this question was asked on this site (not directly, so I don't think this could be a duplicate)

comment Simultaneous Charging and Discharging Capacitor
You have got the concept of a capacitor horribly wrong. A capacitor in the very basic sense is two conducting plates placed parallel to and not touching each other. When you apply a potential difference across these plates, charge accumulates on them and the capacitor gets charged.

comment Free fall from space
ZilbermanRafael What is happening here is that the acceleration $a$ is changing with $r$ when you go to a large height of 500km. Near the surface, this acceleration is equal to $g=-10m/s^2$ and it is approximately constant for small heights. To solve your problem what you have to do is use $GM/r^2$ as you acceleration, and then proceed with solving the differential equation in $r$ and $t$. As @garyp suggests, this requires a certain level of knowledge in calculus.

comment How does a Photocell/Photoresistor work?
Did you read Wikipedia? It explains the basic functioning of an LDR quite well. If you want a more detailed explanation probably about the function of CdS , specify it in the question.

comment Equation of motion for a falling rod (with one end touching a frictionless surface)
@Austin Gravity isn't the only force on the rod, there is a normal force on the rod too from the ground.

comment Where is the “event horizon” on a basketball hoop?
I haven't checked the math, and there is a chance this is not possible. I leave that for you to determine.

Kinda like Millikan's Oil Drop Experiment ?

comment Choosing proper centripedal force in Newtonian gravitational forces
What you need is a proper scale-down factor to try and fit large orbits of satellites around the earth onto your screen so everything is visible properly. What you need to scale-down here is not earth's mass, but the radii of the orbits. So let the mass of the earth be the same, and also the definition of other units, and try to simulate the exact distances which would exist. Then scale-down to make the simulation fit your screen (eg. 500 mtrs -> 50 pixels)

comment How can one calculate the distance a particular sound will travel?
There won't be a definitive point where the wave will "stop". The wave's intensity would exponentially die down with distance, and it greatly depends on the conditions of the medium it is travelling through.

comment From where we can view earth moving?
You can see the earth moving if you are not moving with it.

comment Atwood machine problem
The impulse might have deformed the pulley a bit(compressed it), like an inelastic collision. That deformation will produce heat, which leads to loss of mechanical energy.

comment Constant Velocity 'Force'?
Why do you feel it is "actually not a force"? Is it because you feel the force doesn't cause any acceleration to the body it hits? That is not because there is no force, but because all the forces acting on that body cancel out.

can show a diagram of how it breaks into two rarefaction waves?

comment Period of small oscillations
Given small vertical oscillations, you can assume the motion to be simple harmonic. Then the time period would be given by $2\pi/\omega$.

comment Determine if an object is in orbit
@MrUniverse, If you want to plot a perfect trajectory of an object under influence of multiple massive bodies, you'll have to solve the kinematical equations using newtonian gravity, which is possible(I think) but tough and no general solution usually exists. So you will have to compute the trajectory for every case separately.
