Find the equation of the straight line which passes through the point (0, 3) and is perpendicular to the straight line with equation y = 2x.

We know that a straight line has a general formula: y = mx+c, where m is the gradient of the line and c is the y-intercept; so, we are looking to find m and c. The line passes through the point (0,3) so x=0 ...

A single wind turbine has a maximum power output of 2 000 000 W. The wind turbine operated continuously at maximum power for 6 hours. Calculate the energy output in kilowatt-hours of the wind turbine.

Equation: P = Wt (Power = Work[Energy] x time)1) Convert Watts to Kilowatts (W -> kW)2,000,000W -> 2,000kW [divide by 1000]2) Multiply work by time (remembering the question asks for kWh)2,000kW x 6h =...
