Physics
Steel is very stiff, and the Young's modulus for steel is unusually large, 2.0×1011 N/m2. A cube of steel 25 cm on a side supports a load of 85 kg that has the same horizontal cross section as the steel cube. What is the magnitude of the "normal" force that...

how did the rest of the US feel about war with mexico?

Calculus
the first 2 is centered on the division line which has x-2/(sqrt2)-2. I think I placed the brackets right??

Calculus
No it only has the sqrt x. The -2 is outside of the sqrt. Just so I know. Had it all been under the square root would I have multiplied the top and the bottom by that sqrt(x-2)?

Calculus
The problem is lim --> 2 for g(x) which is 2((x-2/(squareroot x)-2)) I just substituted 2 in for x and 2((2-2)/(squareroot 2)-2) = 0 This doesn't look right. It seems like I'd need to try something different. Can someone tell me if it's right or wrong? And if th...

Evaluate the limits without using a calculator. Justify all steps in the solutions. lim x-->0 x^7cos(3/x)
