Yeah. I agree. I was referring to the representations. If its Kelvin it should be 'degree K'. I got confused as you later refer to 85 degree C in your original post, which is a wide difference to the values of 430 and 500.
Hi Doc Al,
thanks for the thoughts. I visited the following website: http://electron9.phys.utk.edu/phys135d/modules/m3/Projectile%20motion.htm
It says that we can treat motion in two dimensions.
Vx=V0x and Vy=Vy0-gt
and
x = Vx0 t and y = Vy0t - 1/2 g t^2
therefore
t =...
Hi Doc Al,
Thanks for the reply. You have infact echoed my concern too. I think it matters. But when the textbook does not account for it, I am confused.
To give a clearer picture, the objective of the problem is to determine horizontal distance 'S' by which the liquid will be thrown from...
Hi all,
I was trying to find the time required for liquid ejecting from a hole in a tank to reach ground level. The equation given in one of the books is as follows:
t = √(2h/g) or sqrt of (2h/g).
where h stands for the height of hole in tank shell from the ground level.
This...
I was thinking, when positive of battery is connected to a plate, that plate becomes positive. And negative conencted to another plate makes the plate negative. These two plates must be separated by the dielectric. However, whether they will have surface charges is a question.
By using the term capacitor, I was referring to the arragement of plates which resembles of capacitor. There is no actual capacitor in this case. Only battery and set of plates.
sophiecentaur, I agree that a field can possibly raise an object. But there will be instability due to Earnshaw's theorem. I was looking at lifting weights using force of repulsion like in the case of magentic levitaiton (Maglev trains).
I have read in another thread in this forum that the positive charges on the surface of capacitor plate facing away from the dielectric tends to be zero as almost all charges migrate inwards, i.e towards the negative charge. However, if you see magnetic levitation, the force of repulsion between...
There will not be unstability. If at all it works, there will repulsive force on one side of the smaller plate due to positive charges which will be balanced by its weight. It must on the same lines of Maglev train.
Hi all,
I am in the process of developing a science project. That is when I came across different types of levitation including electrostatic levitation. Maglev trains are a good example of magnetic levitation. We know that like charges repel each other.
Its on the last sentence that I...
