Hi,

The surface charge density on an infinite charged plane is -2.2 x 10^-6 C/m2. A proton is shot straight away from the plane at 1.9 x 10^6 m/s. How far does the proton travel before reaching its turning point?

Any idea on how to start this one?


Thanks!

The chemical reaction must be something that would occur around the house. For example, I could not just mix a random acid and a random base together for the reaction.

I don't need to know what exactly weighs one gram, which is, of course, 1 mL of water at 2 degrees celsius and 1 atmosphere of pressure. I just need to know one expample of one object that weighs approximately 1 gram. Anything that weighs 1 gram!

okay here was my last question...If you helped me with the last question, just read the bottom, as I have a question concerning it.

Trigonometry for Physics help (cos, sin, tan)?

okay, we are doing some problems for physics..and im kind of lost...I need help because I have never taken a trig class in my life and this physics book I have doesnt help that much..heres the question.

1. A man walks 5 mi east, then 6 mi North and then 3 mi further East. Make a scale diagram of the man's path on graph paper.

I did this and got 14 mi.

part b) Calculate the straight-line distance from where the man started to where the man ends up. (Is this the same, grater than or less than your answer to part a.

I got 10 mi as my answer which is less than.

Now heres my trouble.

c) At his final position the man turns and points toward his starting point. What direction is he pointing? (Be clear and exact)

Im going to add the rest after I post this because im running out of characters
