You might have to walk me through the steps, because I'm not too experienced with my camera. I need to know the best settings to take pictures of the lunar eclipse, and how to set the settings.

I am majoring in engineering but i dont know which branch to take, any of you know a test or something that will point me to the right direction. Something like a questionare that will ask me some of my skills and then suggest an enginerring branch.

Any help will be appreciate it!

The membrane of a living cell can be approximated by a parallel-plate capacitor with plates of area 4.75 x 10^-9 m^2, a plate separation of 8.5 x 10^-9 m, and a dielectric with a dielectric constant of 4.5. (a) What is the energy stored in such a cell membrane if the potential difference across it is 0.0725 V? (b) Would your answer to part (a) increase, decrease, or stay the same if the thickness of the cell membrane is increased? Explain.

Thanks so much!

The Earth has a mass of 5.98 1024 kg. The average mass of the atoms that make up the Earth is about 38 u. How many atoms are in the Earth?

Suppose that it takes 12 h to drain a container of 5700 m3 of water. What is the "mass flow rate," in kilograms per second, of water from the container?

A typical sugar cube has an edge length of 1 cm. If you had a cubical box that contained a mole of sugar cubes, what would its edge length be? (One mole = 6.02 1023 units.)

For about 10 years after the French revolution, the French government attempted to base measures of time on multiples of ten: One week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100 seconds. What is the ratio of the French decimal week to the standard week? What is the ratio of the French decimal second to the standard second?


Please and thank you!

in maths,topic of limits....

we know,,if limit x->0 tanx/x=1
sinx/x=1
cosx/x=1 if limit x tends to zero
my question is this ,is that possible
cotx/x=1
cosecx/x=1
secx/x=1 iff limit x tends to zero
