The objective for this question is to work out what number 'x' represents in order for this equation to be true. This simply means that we want to find the number that 'x' equals, so we ...

The total number of pens they need is 4 + 7 + 11 = 22However pens only come in packs of 10 so they have to round up the number of pens they need to the nearest 10 ... this is 30. Then 30 divided by 10 is ...

F = G(Mm/r^2)F = mv^2/rG(Mm/r^2) = mω^2rω = 2π/TG(Mm/r^2) = 4π^2mr/T^2GM/r^3 = 4π^2/T^2T^2 = r^3 (4π^2/GM)

dy = sin(2x)cos(2x) dxlet u = sin(2x)du/dx = 2cos(2x)dx = du/2cos(2x)dy = (cos(2x)/2cos(2x))dudy = du/2y = u/2y = sin(2x)/2

At rest (steady state) there is a greater concentration of Na+ ions and a smaller concentration of K+ ions on the outside compared to the inside of the cell, and the membrane potential is about -70mV. Upo...
