A stadia measurement was undertaken with a theodolite having an internal focusing

telescope and stadia interval factor of 98.8. When a backsight was taken on a turning

point whose elevation is 205.62 m, the rod interval observed was 1.94 m; and with the

horizontal hairs set at 1.50 m on the rod, the vertical angle reading was +13045’. For a

foresight to a control point, the rod intercept was 1.17 m; and with the horizontal hair

reading of 1.60 m on the rod, the vertical angle observed was -7018’. Determine the

elevation of the line of sight at the instrument point and the elevation of the point on

which the foresight was taken.

Explain the modes of transfer on input- output organization

The unique addresses assigned to the four registers (R11,R12,13,R14) of the I/O interface are equal to the XX3 , XX7 , XXB and XXF in Hex . Where XX is hex digits equal to your roll no . (if student is having roll no 45 than address are 453 ,457 ,45B , 45F in Hex ) .Show the well labeled external circuit that must be connected between and 12-bit I/O address from the CPU and the CS, RSI, and RS0 Inputs of the Interface. 

A 12V battery has an internal resistance of 0.05Ω. Two loads are connected in parallel across its terminal, the first drawing a current of 12A and the other taking a power of 200 watts. Determine the load terminals voltage?

Five batteries are connected in parallel to supply a certain load. Each battery consist of 12 cells in series. Each cell has an emf of 2V and the internal resistance of each cell is 0.15Ω. What should be the resistance of the load so that the total power consumed is 384 watts?

A cable is suspended between two supports at the same elevation 250m high and 500 m apart. The load is 500 kg per horizontal meter including the weight of the cable. The sag of the cable is 50 m. calculate the total length of the cable.
