how would you solve a problem like this for X: (1/3=(3^2x+2)
In the following reaction, how many grams of ferrous sulfide will produce 0.56 grams of iron oxide? 4FeS+7O2->2Fe2O3+4SO2 The molar mass of ferrous sulfide is 87.92 grams and that of iron oxide is 159.7
An object whose mass is unknown is held by two rigid rods. The whole system is at rest. The angle between the vertical direction and the left rod from point A to B is 60 degrees. The angle between the vertical direction and the right rod from point C to D is 30 degrees. The fo...
Two cars lost in a blinding snowstorm are traveling across a large field, each thinking they are on the road, as shown in the figure on the left. They collide. If the distance x is 150 meters and the red car is travelling at 19.1 mph, how fast to the nearest hundredth of a mph...
A pinhole camera has a small circular aperture of diameter D. Light from distant objects passes through the aperture into an otherwise dark box, falling on a screen at the other end of the box. The aperture in a pinhole camera has diameter D = 0.600 mm. Two point sources of li...
The functions f(θ) and g(θ) are sine functions, where f(0) = g(0) = 0. The amplitude of f(θ) is twice the amplitude of g(θ). The period of f(θ) is one-half the period of g(θ). If g(θ) has a period of 2pi and f (pi/4) = 4, write the function r...
