Is that correct? Or what would be the correct probability we're looking for? I'm receiving too many different answers.

Finally, I've found the probability as ##0## from ##P = \dfrac{1}{4}exp \biggr( \dfrac{-2t\mu BB}{\hbar}\biggr ) \biggr | (1-1) \biggr |^2 = 0## Does that seem correct now? Thanks in advance.

I found the probability as ##\dfrac{B^2}{2}## is that correct?

Today,in our class, we received a trigonometric equation ##\sin^{10}{x}+\cos^{10}{x}=\frac{29}{16}\cos^4{2x}## Here is my attempt:

Do you see any mistakes at the final answer? And yes, I'm assuming that the system in state ##\chi_+^{(x)}## at time ##t=T##. Staying tuned for your sincerely reply!

Homework Statement Homework Equations I didn't get what this actually means. The Attempt at a Solution I'm not sure whether it is correct. Could you take a look? Regards!

All my teachers had found anohter answer for this question (1.34pm, 1.35pm and 1.36pm). And yes, there are too many different answers. I'm checking If that's wrong or not. However, it seems correct. Now let's look at textbook solution, it says that the answer is 1.36pm.

For BCC; a = 4r/√3 mass of Ba atom = 137.327 g/mol mass of 1 atom = 137.327 g / 6.022 x 1023 = 2.28 x 10-22 g density of bulk = density of unit cell total no. of Ba atoms in BCC = 2 atom mass of 2 atom = 2 x 2.28 x 10-22 g = 4.56 x 10-22 g mass of atoms / volume of unit cell = 3.51 g/cm3...

However, are those correct? or is there only an answer? It seems like different on wikipedia and others.

I'm getting too different answers for atomic radius of iridium. I've already found 1.34 x 10-8 but all shows different answers. I mean like 1.34, 1.35, 1.36... Are those correct?

That's all are d = m/v but I don't know how to apply it.

A overflow container that its overflow level is $100$ $cm^3$ has $80$ $cm^3$ water. When a stone that is $120$ $g$ is being dropped into the overflow container, the water increases $10$ $cm^3$. How to find the density? I currently don't have any idea about it.
