I hope someone can show me how to work out these problems step by step. I am having trouble with my chemistry homework.
The quetions are:

At 3.00 m from a radioactive source the intensity of its gamma radiation is 202 roentgen. How far away would we need to be to reduce the intensity to 4.64 roentgen.

At 2.00 m from a radioactive source the intensity of its gamma radiation is 522 roentgen. What is the intensity at a distance of 37.8 m?

I would appreciate any help.

I am trying to teach myself intermediate algebra. I am usually very good at these things, however, at the moment I am have trouble getting started. If anyone can tell me of any study music/sounds that may help, or a technique to calm me down, or just anything that will get me started on this so I don't have to worry about it anymore. Please and ThankYou

What are important ideals all scientists must share? Who makes a good scientist? How can a scientist make accurate and un-biased claims? Where is science going for humanity? What changes do we need to make in funding science?

I'm a state certified teacher in Arizona and want to know if there is an application program that others use to make their handouts and exams. I want to do some tutoring and would find it really helpful if I could write equations and formulas as they appear in text books.

This is the post from a while ago -

"They say a light year is the distance travelled by light in 1 year. So now if some star is said to be 10 billion light years away, it means it must take light some 10 billion years to get to us, which means that whatever we are seeing of that star at this time is actually 10 billion year old story & what may exist that far right now might be very different than what we can see"

Analogous to the above concept, theoritically, anything travelling (towards us) faster than light would always be invisible, isn't it? If, at this time, something is headed for earth, travelling faster than light, we will never even see it before we are hit. Armageddon without warning... any of you think that could be a possibility?

A shadow universe in which our bodies exist in a compressed two-dimensional form. This could mean we live in a hologram. Is this scary or what? What's your opinion on this matter?

Because it involves the collision of two branes (membranes) .The universe is flat! Its possible another universe will collide with ours in the near future as there are other membranes floating out there in hyperspace. What do you think?
