3. If the source documentation says that the gamma-ray exposure rate at a distance of 102cm is 25.8 µC/kg/h air kerma and we wish to calibrate the 0.11 mGy/h air kerma midpointon the scale of an instrument that measures 0-25 mR/h air kerma, at what distance fromthe calibration source should the detector be placed?

You have stated that the convective area is πr^2. Please explain this. πr^2 is the area for a circle, not a sphere. It should be 4πr^2 as this is equal to the surface area of the sphere as you have done correctly in the radiative area. A conv= 4πr^2*3*293-292 = 0.377 A rad = 4πr^2*0.2*5.67x10^-8*(292^4-291^4) = 0.144 I have tried to multiply the convective area by 4πr^2 instead of πr^2 but it is giving me an incorrect total heat transfer rate of 0.377+0.144 = 0.521 the correct answer is supposed to be 0.236
To correct the vision of a hyperopic eye, a corrective lens should enable the wearer to focus on objects that are as close as the ideal near point. One way to think of this is that the corrective lens should take an object located at the ideal near point and create an image of it at the wearer's near point. (Remember that the wearer's eye is a short distance behind the corrective lens.) Draw a ray diagram showing this situation and find the necessary focal length of the lens in terms of the wearer's near point, the ideal near point, and the distance between the corrective lens and the eye.
