These types of problems are as follows:
sin (arc sin 3 pi / 4)

tan (arc tan 7 pi / 6)

Etc. How can you do these types of problems? I'm really stuck , any help would be greatly appreciated!

1. A 250cm^3 solution of NaOH was prepeared. 250cm^3 of this solution required 28.2cm^3 of 0.100 M (mol/dcm3) HCl for nuetralisation. Calculate what mass of NAOH was dissolved to make up the original 250cm^3 solution.

HCl + NaOH -> Nal + H2O

2. What volume of 5M (mol/dcm^3) HCl is required to nuetralise 20kg of CaCO3?

2 HCl + CaCO3 -> CaCl2 + H2O + CO2



im stuck would really appriciate some help thanks :)

A shop makes tables and chairs. Each table takes 8 hours to assemble and 2 hours to finish. Each chair takes 3 hours to assemble and 1 hour to finish. The assemblers can work for at most 200 hours each week, and the finishers can work for at most 60 hours each week. The shop wants to make as many tables and chairs as possible. Write the constraints for the problem, and graph the feasible region. Let t be the number of tables and c be the number of chairs.

I don't mean from a pollution aspect, I mean from the aspect of changing the lay of the land? For example, do taller buildings have a significant change on wind speeds or directions? Does the heat being generated change anything?

Is there any impact on any weather processes in general?

Way to bright to be normal...I think is something else and they are trying to explain it to cover it up

Just checking to see if I've made any mistakes in my hw problems...
1. A block of mass m is at rest on an inclined plane as shown in the figure. Find an expression for the static friction in terms of the mass , the acceleration of gravity, and and the angle shown.
1. The attempt at a solution:
http://www.physicsforums.com/attachm...3&d=1194247920
Newtons 1st Law
sum of forces = 0
mg cos(a) -μs * mg sin (a) = 0
μs = cos(a)/sin(a) = cot(a)
thus: static frictoin = cot(a)*cos(a)
2. A proud new BMW owner drivers her car at a speed of 25 m/s into a corner. The coefficients of friction between the road and the tires are 0.70 (static) and 0.40(kinetic). What is the minimum radius of curvature for the corner in order for the car not to skid?
2. Speed(v) of honda = 25 m/s
Coefficient of kinetic friction(μk) = 0.40

I've always lived on the seacoast in Massachusetts and could never imagine living inland. I understand there are beautiful rivers and lakes out there but there's nothing like the sea.
