Name the quantity which is measured in (a) kWh (b)kW (c )Wh (d)eV

Let f be continuous,and strictly monotonic increasing,on [0, a l Let g=f^(-1). If f(0)=0,0 =wh. Hence evaluate int_(0)^((pi)/(2))sin xdx int_(0)^(1)sin^(-1)xdx

Two short bar magnets of length 1cm each have magnetic moments 1.20 Am^(2) and 1.00 Am^(2) respectively. They are placed on a horizontal table parallel to each other with their N poles pointing towards the south. They have a common magnetic equator and are separted by a distance of 20.0 cm . The value of the resultant horizontal magnetic induction at the mid - point O of the line joining their centres is close to (Horizontal component of earths magnetic induction is 3.6 xx 10.5 Wh//m^(2)
