A 1.0 102 g piece of copper at a temperature of 460 K and a 2.0 102 g piece of aluminum at a temperature of 2.2 102 K are dropped into an insulated bucket containing 5.0 102 g of water at 280 K. What is the equilibrium temperature of the mixture? (Use the specific heats found ...

Does the series ln/n^2 converge using the L'Hoptial's rule also. I know you can use the integral test but I have also seen others using the L'Hopital's rule on a very similar funciton ln/n^3 to see that it does converge.

Two people are talking at a distance of 3.4 m from where you are, and you measure the sound intensity as 1.0 10-7 W/m2. Another student is 4.2 m away from the talkers. What sound intensity does the other student measure?

A 5-m-long string, fixed at both ends, has a mass of 9 g. If you want to set up a standing wave in this string having a frequency of 298 Hz and three antinodes, what tension should you put the string under? I got 0.009kg(a984.68m/s)^2/5=7090 N it still says its the wrong answer
Physics
Your saying g=9.06
Physics
For some reason its still saying its the wrong answer
Physics
It still says its the wrong answer. Let me calculate it again

Imagine you are an astronaut who has landed on another planet and wants to determine the free-fall acceleration on that planet. In one of the experiments you decide to conduct, you use a pendulum 0.47 m long and find that the period of oscillation for this pendulum is 1.43 s....
