Your samples contained both Al and F, although the composition was not specified in this lab. Suppose you were given a second sample that contained the same amount of Al, but twice the amount of F. What changes would be observed in the data obtained in channel A, and how would this affect your calculated value for t1/2 of 20F ? There would be no observable changes in the data. The intensity of 20F signal would be higher, and the lifetime would be twice as long. The intensity of 20F signal would be higher, but the lifetime would be unchanged. The intensity of 28Al signal would be higher.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
