    What is the largest angle for sin and tan to agree within 2 significant figures?

    hmm well basically its saying find the highest value of Ø such as sin(Ø) = tan(Ø) up to the second decimal place. I am guessing a lot of guessing/checking?

    How Long Does It Take for a Wrecking Ball to Fall to the Ground?

    well, downward acceleration on Earth (or g) is always a constant 9.81 m/s2 so ll you have to do is plug into the equation so just plug that into the equation D = D0 + V0t +(1/2)at2 to find the half of the distance, then double to find the total distance. then we change the equation v2 = v02 +...

    What is the Diameter of an Oil Slick Spreading on a Lake?

    first, convert the volume of oil from cm^3 to m^3. now we work backwards first divide the volume of oil by the thickness of one molucule by doing this what happens is m3/(m becomes m^2 which is area, therefore you have now solved for the surface area. now since it says diameter I am assuming...
