A conducting bar slides down without friction on a pair of conducting rails separated by distance d. Connected to resistor R and there magnetic field B directed upward, perpendicular to the ground over the entire region through which the bar moves.
1) find the current
Since i only know the field direction, increasing go into page. Why the answer is C?
Why the answer "a" ?
The R and r on the pic is respected to what?
The Attempt at a Solution
Right hand rule : finger tip = current
Thumbs = force
Palm = B
A point particle of mass m and charge q(>0) approaches to a point particle Q(>0) at a fixed position. When the distance between the two particles is L, the speed of the moving particle is v. The permittivity of the vacuum is denoted as Epsilon0. Find the minimum distance...

The displacement y of standing wave that is obtained by a superposition of waves :
Y1 = 3 sin (2##\pi##(0.5t - 0 25 x))
Y2 = 3 sin (2##\pi##(0.5t + 0 25 x))
Formula for standing waves
Y = 2Asinkx coswt

Then, what is formula for Ek per n mole? 3/2nRT?
When Ek for N molecule = 3/2NkT.
Why is it the same formula as ##\Delta##U?
##\Delta##U is the total of Ek and Ep of molecules. If we asked to find Ek is the same as we find ##\Delta##U? Or what?
Do we calculate Ek at certain temperature or we calculate Ek based on the temperature change?
If there is no heat transfer/adiabatic (number 2) then the Q is the same, does it imply that temperature is the same?
