Solving Exponential Decay: 10,000 Years & Uranium II

AI Thread Summary
The discussion centers on calculating the remaining percentage of radioactive Uranium II after 10,000 years, given its half-life of 250,000 years. Participants emphasize the importance of not providing complete solutions to homework problems, as this undermines the learning process. An algebraic approach was attempted, but the accuracy of the calculations was questioned. There is a call for clarification on the relevant equations for radioactive decay to aid understanding. The conversation highlights the balance between helping students and ensuring they engage with the material independently.

Homework Statement



The half life of radioactive Uranium II is about 250,000 years. What percent of radioactive uranium will remain after 10,000 years?


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
for every 250000, there is 50% left from original mass
10000/250000=.04 of what?

There is an equation, but over here its night time and my brain is turned off, so i did it algebraicly

silvashadow, did you read the rules? Do not post complete solutions to homework problems. Our job is to help students learn. Simply giving the answers is not helping them.

Even more importantly, do not post incorrect solutions. The algebraic approach is approximately correct.

amanaka, do you know what the relevant equations are for radioactive decay?

I'm so sorry. Please forgive my incompetence.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
