Thanks for the replay Shyan.
a circel with a diameter of 1.29mm 0.6452π = 1.30 The formula you mentioned √s/π gives a value of 0.362.. ?
Could you show me an example, I would be very thanks full
Hi
How is circular surface area values square rooted ??. I am using this formula r2Xπ=mm2 to calculate the surface area of a circle but i want to know if there is a formula to get back to the diameter or the radius of the circle ?.
example i have a circular surface area of 5.26mm2 and i want...
I have had no problem with measuring DC currents, did the same experiment with a light bulb and got what i expected, higher resistance.
Does the resistance get higher with the temperature on every conductor Copper, Aluminum, ect ?
Hi guys
I have been playing around with a piece of tungsten wire by supplying it with 12Vdc and measuring the current draw to see how much the resistance changes when the wire is glowing hot. while doing this i am not getting any change in the resistance, the wire has the same resistance when...
Hi
I have seen electric technicians while racking out high tension circuit breakers, use a wire that has one end grounded and they use the other end to touch the bus bars on the breaker in case of a static charger, they carry out this procedure before they do any work on the CB in case they...
Lets assume that we have a stone and a surface that don't deform, would dropping the stone down on the surface not result in any sound ?
I appreciate your kind responds : )
so speaking in simple terms, there is nothing purely rigid in this world every thing deforms during a collision, and that is what is responsible for the bouncing effect that we can observe, am i right ?
P.S
Is it possible to observe the deformation of an very rigid/solid object during a...
Hi guys
enlighten me, How can Rigid bodies with smooth surfaces bounce in a collision
An example is, drooping a metal sphere on a metal surfaceis there any deformation happening here as in the situation of a basketball ?
Well what I mean is,
example when we spray water at an object let's say a standing piece of plywood, the ply wood will fall down due the the force of the water particles hitting the plywood, Well how does the magnetic force work ? is there any atom,particle collisions causing the force ?
