Consider the bandwidth of the line is 1.2mbps, packet size is 1KB, and round trip time is 50 msec. What is the link utilization in stop and wait?

A person rides a bicycle round a circular path of radius 50 m. The radius of the wheel of the bicycle is 50 cm. The cycle comes to the starting point for the first time in 1 hour. What is the number of revolutions of the wheel in 15 minutes ?

A football player, starting from rest at the line of scrimmage, accelerates along a straight line for a time of 1.5 s. Then , during a negligible amount of time, he changes the magnitude of his acceleration to a value of 1.1 m//s^(2) . With this acceleration, he continues in the same direction for another 1.2s, until he reaches a speed of 3.4 m/s. What is the value of his acceleration ( assumed to be constant ) during the initial 1.5 s period ?

A pilot is supposed to fly a certain distance AB , due east from A to B and then due west from B to A . The velocity of plane is v and that of air is u . The time for the round trip is t_0 in still air. Show that (a) if the air velocity be due east or west, the time for round trip will be t_1 = (t_0)/((1 - (u^2)/(v^2)) . (b) if the air velocity is due north or south, the time for a round trip will be t_2 = (t_0)/sqrt((1 - (u^2)/(v^2))) . .

Consider the two lines x+y+1=0 and 3x+2y+1=0 What is the equation of the line passing through the point of intersection of the given lines and parallel to x-axis ?

Consider the bcc unit cells of the solids 1 and 2 with the position of atoms as shown below. The radius of atom B is twice that of atom A. the unit cell edge length is 50% more in soild 2 than in 1 . What is the approximate packing efficiency in solid 2?

Consider the situation shown in (figure) what are the signs of q_1 and q_2 ? If the lines are drawn in proportion to the charge, what is the ratio q_1/q_2 ?
