I was doing a first year imaging lab (in radiography course). We were supposed to check the alignment of the collimation light, and how accurate it represents the x-ray "beam". One of the question in the task question is to determine "the x-ray fields (express this answer in cm and a percentage...
I don't get why Q6 response is wrong, well as far as I understand force constant of a spring shows us how stiff it is. If two identical springs connected in 'series', the stiffness of the 'combined' spring doesn't change. If we don't increase the mass, i.e. no change in weight force, the...

This isn't acctually a problem but I really don't know what to do. I was doing a simple activity about Hooke's Law during class today where I have to set up a apparatus and measure the extension of spring when when we put differnt masses on it. I didn't do it properly so I...
