To solve this problem we will use the principle of conservation of energy. The gravitational potential energy of the ball at the maximum height must be equal to the kinetics energy at the bottom plus the ...

Convection is transfer of energy through movement of liquid particles. Let us take some steps back and revise a number of principles. First of all, you should remember the concept of density. If two parts...

First we need to start by multiplying the brackets on the right, which will give us:2x^2 + x = x^2 - 4x - 4Then we need to move everything that is on the right to left:2x^2 + x - x^2 + 4x + 4 = 0Here a co...

Always draw a diagram first to help with clarity.Correct use of Sine Rule:sin(A)/BC = sin(C)/ABTherefore sin(C) = ABsin(A)/BC sin(C) = 20sin(70)/100 sin(C) = 0.188 (rounded to 3 Significant Figures) C = a...

Tropical storms can only form between approximately 5° and 30° latitude, as the revolving aspect utilises the Earth's Coriolis effect in order to enable it to spin. Furthermore, the must form above bodies...
