The variables we are given are mass (m), time (t), temperate CHANGE (delta T) and SHC (c) and we are asked for energy. Think of the equations for energy we know: mgh, 1/2mv2, mcdeltaT...the fir...
a) Current is defined as the rate of flow of charge; I = Q/t (Current is charge/time).b) Voltage is an electromotive force which drives the charge around the circuit. A potential difference between two po...
So we need to break this down into two parts, what are Newtons laws and what is terminal velocity? In this case we will only need the first two of Newtons laws. Number one " An object will remain at ...
Distance is a scalar which means it only has a length- it is the length of distance travelled along a pathDisplacement is a vector which means it has a direction and a length and is the total change in po...
In a free body diagram for a box on a rough slope, there will be three arrows. One will point out of the box up the slope (parallel to the slope), one will point directly downwards from the box, and the f...
