A polar covalent bond shows 50% ionic character. What should be the electronegativity difference of the atoms that form a polar covalent bond?

A staircase has each step of height h and width x. A ball strikes the centre point of a step with velocity v making an angle theta with the vertical. It rebounds and strikes the centre point of the next step. Once again it rebounds and hits the centre point of the next step and so on. Assume that there is no friction between the ball and the steps and coefficient of restitution is e. (a) Show that each time after hitting a step, the ball climbs to the same height (i.e., heights like AB and CD shown in figure are equal). (b) Find h and x.

Figure shows a situation similar to the previous problem. All parameters are the same except that a battery of emf epsilon and a variable resistance R are connected between O and C. The connecting wires have zero resistance. No external force is applied on the rod (except gravity, forces by the magnetic field and by the pivot). In what way should the resistance R be changed so that the rod may rotate with uniform angular velocity in the clockwise direction? Express your answer in terms of the given quantities and the angle (theta) made by the rod OA with the horizontal.

With their lives on the line and to protect the city, Iron Man and Jarvis are working on to build an impenetrable and unbreachable wall around the opening so that no more enemies can show up. Tony has completed a part of the wall and has left Jarvis to do the rest. Jarvis is only permitted to use the blocks of dimensions 2xx1 and 1xx2 (length x height) but he has an infinite number of these blocks. A wall is said to be completed if it is in the form of a complete cuboid with no holes in between. In each case, the first number is the length of the wall say n and, n integers are the initial heights of the wall (made by Tony) each of unit length. What is the minimum number of blocks required in Case 2?
