Thin, uniform rod with negligible mass and length 0.200 m is attached to the floor by a frictionless hinge at point P(the figure (Figure 1) ). A horizontal spring with force constant k = 4.80 N/m connects the other end of the rod to a vertical wall. The rod is in a uniform magnetic field B = 0.330 T directed into the plane of the figure. There is current I= 6.50 A in the rod, calculate torque on rod?

A metal bar of length L =10 cm is free to move along a metal guide on a horizontal plane forming a rectangle electric circuit with resistance 2 ohm. There is a non uniform magnetic field in the plane which varies according to the law B(x,t)=c(x-ct) where k=2wb/m^3 c=3.10^8ms. Assume to move bar with constant speed v=5m/s along x ,determine the expression of electric current.?

Read the passage given below and answer the following questions:The amount of moisture that leather adsorbs or loses is determined by temperature, relative humidity, degree of porosity, and the size of the pores. Moisture has great practical significance because its amount affects the durability of leather, and in articles such as shoes, gloves and other garments, the comfort of the wearer. High moisture content accelerates deterioration and promotes mildew action. On the other hand, a minimum amount of moisture is required to keep leather properly lubricated and thus prevent cracking. The study indicates that adsorption of moisture by leather is a multi- molecular process and is accompanied by low enthalpies of adsorption. Further at 75-percent relative humidity, the adsorption is a function of surface area alone. Untanned hide and chrome- tanned leathers have the largest surface areas. The leathers tanned with vegetable tanning materials have smaller surface areas since they are composed of less hide substance and the capillaries are reduced to smaller diameters, in some cases probably completely filled by tanning materials. This process of tanning occurs due to mutual coagulation of positively charged hide with negatively charged tanning material. The result of the study indicated that untanned hide and chrome-tanned leather absorb the most water vapour.In these questions a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices.Assertion (
