At a distance of 10 cm from a presumably isotropic, radioactive source, a pair of students measure 74 cps (cps = counts per second). on average, how many counts per second do you expect at a distance of 22 cm? (note that the average number of counts per second need not be an integer.)

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
