Write a short note on electronic waste. List the various sources of e- wastes and the problems associated with its disposal.

Let E be an ellipse such that x+y= 2sqrt5 is a tangent to E and E passes through (3,-1). If axes of E are along the coordinates axes and e is the eccentricity of E, then e^2 equals _____

The terminal potential difference of a cell when short-circuited is (E = E.M.F. of the cell)

Write a short note on: Production of human growth hormone by E.coli.

What should be the value of E_1//E_2 so that current flowing through 7 Omega resistor could be increased by short- circuiting the battery of emf E_2 ?

In the circuit shown in fig E_1 = 3 volts, E_2 = 2volts, E_3 = 1volt and R = r_1 = r_2= r_3= 1 ohm. (i) Find the potential difference between the points A and B and the currents through each branch. (ii) If r_2 is short circuited and the point A is connected to point B, find the current through E_1, E_2, E_3 and the resistor R.
