Physics
In the 1950s, an experimental train that had a mass of 3.30 104 kg was powered across level track by a jet engine that produced a thrust of 4.90 105 N for a distance of 600 m. (a) Find the work done on the train. J (b) Find the change in kinetic energy. J (c) Find the final ki...

Science
If 5.6 mol of CuCl2 reacts with 10.2 mol of NaNo3, what is the limiting reagent?

physics
A charge of 3.0 nC and a charge of 5.8 nC are separated by 53.40 cm. Find the equilibrium position for a -4.7 nC charge.

On the contrary, time is flying, I gotta get going. I could be writing a masterpiece instead of complaining. I'm gonna make use of the time I have. Thanks for your support, Ms. Sue, it's been a pleasure talking to you. (:

Lol yeahh! But then I hand it in thinking it's an A+ and it turns out I get a B or something. You'd think I'd at least get an A- for effort...sigh.

I'm writing a poem and it requires me to list reasons on what you want your significant other to do to make you happy. SEEMS EASY ENOUGH, RIGHT? So I want to hear your thoughts on this particular topic :D

chemistry
yes it would-- don't doubt your answers even if the numbers seem odd lol

chemistry
Did you try to use the density formula D=m/v? Solve for m that way...

Chemistry
It is found that an unknown gas has a density of 2.5 times that of Oxygen gas of the same Temperature and Pressure. What is its molecular weight?
