What do you understand by average nuclear binding energy per nucleon? Explain the implications for the stability of a given nuclide of a high value of the average binding energy per nucleon. Sketch a binding energy curve and indicate the region of maximum nuclear stability.

It emits α and γ radiation with a half-life of 3.8 days. If present in high concentration, it is a significant health hazard. Suppose that a health inspector finds an activity level of 2 x 105 Bq in the basement.

(i)What will the activity after 7 days?
(ii)What will the activity after 14 days?
(iii)How long must the residents of the house wait until the activity has decreased to 1 Bq?

If we produce a microscopic blackhole and that black hole remains in our dimension for a period of 5 minutes before detachment do you think it will pull in the surrounding particle accelerator? How far away will the gravity travel from the microscopic black hole?

If there is dust in the accelerator tunnel will the black hole pull in all the dust to increase its size?

A few years ago in 7th grade science, I learn that when water is frozen the particles of matter move in close to each other, they go from being spread out, to being tightly bound. If this is true, then ice should be smaller than it was when it was water. So why does it expand

Many years ago, i did an experiment to discover this very fact.
I think i f**ked it up, and besides can't remember now.
I've read that it's approx 4 times faster than in air, is this true?
Well i suppose whilst we're at it, so then has anyone broken the "in water" sound barrier?

And are there any other things involved? I'm talking about things like a person "walking" on water and cars driving on top of a large mass of water. I'm sure theres some sort of equation for this. This has nothing to do with religion, just scientific curiousity.
