Food producers can irradiate food by passing it close to a radioactive source. How can food producers increase the level of radiation that the food is exposed to?
Tick two boxes.

A) Boil the food before passing it close to the radioactive
source

B) Decrease the distance between the food and the
radioactive source

C)Increase the time for which the food is close to the
radioactive source

D)Put the radioactive source in a box

E) Reduce the temperature of the radioactive source

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
