Physics
so do you not need the diameter for anything?

Physics
Rotating initially at 1800 rpm, a wheel with a diameter of 74.0 cm is brought to rest in 11.0 s. Calculate the magnitude of its angular acceleration in radians/second^2

chemistry
we have a bag that can hold up to 775 ml. we have baking soda and 6 molar of hydrochloric acid. how can we find out how much baking soda and acid we need so that when they react, the gas will fill the bag up just enough so that it wont pop

Crime scene chemistry
we dont know.

physics
A uniform electric field of magnitude 339 N/C is directed along the +y-axis. A 6.00 µC charge moves from the origin to the point (x, y) = (-40 cm, -33 cm).What is the change in potential energy associated with this charge ?

Chemistry
yes

math
yes, excellent, that is correct, as well as the answer

algebra
1st part 69m @ X+5mph 2nd part 23m @ X so,69m/x+5 + 23m/x = 2hours 69/x+5 + 23/x = 2 LCD ==> 69(x)+ 23(x+5)= 2x(x+5) 69x+23x+115=2x^2+10x 92x+115=2x^2+10x 0=2x^2-82x-115 wont factor, use quadratic formula x=(-b}ã(b^2-4ac))/2a x=-(-82)}ã...

Geometry
volume of a sphere (4/3)(3.14)Radius cubed, so, 4/3*3.14*6*6*6 = 904 cubic feet of water, but, you only want it "half" full 904*1/2=452.39 cu. ft. of water

trig
100cos10=x 100sin10=y <x,y>
