Two conductors are made of the same material. Length of conductor 1 is triple that of length of conductor 2. Conductor 1 is solid wire of radius D and conductor 2 is hollow tube of outside diameter 4D and inside diameter of 2D. Find the resistance ratio R1/R2 measured between their ends.

It took 2 milliseconds for the goalkeeper to make the ball at rest in his hands. Assuming constant force was applied by the goalkeeper during this time, what will be the value of force applied by the goalkeeper? 1490 N 1752 N O 666 N 3920 NCalculate the fermi energy of a good conductor which has number of conduction electrons per unit volume = 5.9x 10 28 /m 3 5.54 eV 2.21 ev 11.6 eV 7.06 evTwo ideal polarizing sheets are stacked so that none of the incident unpolarized light is transmitted. A third polarizing sheet is slipped between the first two sheets such that 10 percent of incident light is transmitted through the stack. Find the angle of the third polarizing sheet. 11.6 degrees 5.8 degrees 39 2 degrees 19 6 degreesA storage tower of height 30 m and diameter 3 m supplies water to a home. The horizontal pipe at the base of the tower has a diameter of 1 inch which delivers water at a rate of 180 liters per minute. A smaller pipe of diameter 0.5 inches supplies the third floor of the house at a distance 7 m above ground. What is the water pressure on this pipe?

After collision, particle A is deflected by 30 degrees anticlockwise. Assuming collision was elastic, determine the angle between velocities of particle A and B. 60 degrees 30 degrees Can not find without knowing the value of m. 90 degrees
