Atomic and Nuclear Physics Answers

A blood corpuscle has a diameter about 9x10-6 in which excited orbit should a hydrogen atom should be so that it is just about as big as the blood corpuscle?

Tungsten (W), with a mass number of 185 and an atomic number of 74, decays by beta emission. Identify the product of the nuclear reaction by providing its atomic symbol (5 pts), mass number (5 pts), and atomic number (5 pts)

Hello.I want to ask is it possible for a stone to have some magnetic power different from power that we see in ordinary metal magnets.something like earth gravity that attract everything.Some one told me that he saw a stone that attract other smaller stone but did not attract metals.
Is it practical possible in science?

neutron breaks into proton and electron. the energy released during this process.

The half life of radon is 3.80 days. What would be its decay constant?

Can we create mass from energy and is it possible to make anti nuclear reactor.????

a copper calorimeter of mass 100kg contains 50g of water and 5g of ice at 0 degree celcius.what mass of steam at 100 degree celcius must be passed to the calorimeter to raise the temp to 30 degree celcius.

how the energy is produced in a nuclear reactors?

1. A decommissioned nuclear power station still produces 0.5 MW of power five years after being turned off. Assuming that each decay releases 0.16 MeV of energy, calculate activity of the reactor in Kilo becquerels (KBq).

2. The ratio of carbon-14 to carbon-12 in a prehistoric wooden artifact is measured to be one-sixteenth of the ratio measured in a fresh sample of wood from the same region. The half life of carbon-14 is approximately 5,730 years. Determine its age.

3. What was the effective dose received by a cancer patient who received 2.8nSv to his lung and 350(mu)Sv to his colon. Compare your result with a normal background radiation and make and informed guess as to how likely the patient is to develop somatic effects after treatment
