Create an illustration of a series circuit that connects a battery and five capacitors and with a total capacitance of 3/7 F. The total charge in the circuit must be 2/9 C.

A 1OL volumetric container weighing 6.2 kg has been packed with gravel by the required method, and then the total weight is 2 1.3 kg. Calculate the bulk density of gravel. If water is filled into the container, the total weight

Calculate the volume of the solid formed by revolving about the line y=1 the region bounded by the parabola

x

2 = 4y and that line. Take the rectangular elements of area parallel to the axis of revolution.

A 50m tape of standard length has a weight of 0.05 kg/m, with a cross sectional area of 0.04 sq.cm. It has a modulus of elasticity of 2.10 x 106 kg/cm2 . The tape is of standard length under a pull of 5.5 kg when supported throughout its length and temperature of 20°C. This tape was used to measure a distance between A and B and was recorded to be 458.65 meters long. At the time of measurement, the pull applied was 8kg with the tape supported only at its end points and the temperature observed was 18°C. Assuming coefficient of linear expansion of the tape is 0.0000116/°C.

(a) Compute the correction due to the applied pull of 8 kg.

(b) Compute the correction due to weight of tape. 

(c) Compute the true length of the measured line AB due to the combined effects of tension, sag and temperature. 

The hectare is the most commonly used unit of area for large tracts of land. It is equal to
