Neco 2025 Agricultural Science Question 36
Practice objective / multiple choice question 36 from the 2025 Neco Agricultural Science examination.
A tractor is used to pull a single-bottom plough. The engine consumes \(1.0\) litre of diesel per hour. Diesel has an energy content of \(42\) MJ per litre and the engine thermal efficiency is \(30\%\). The power transmitted to the drawbar is reduced by a transmission efficiency of \(85\%\). The tractor moves at a constant speed of \(5\) km\(\)/h. The draft force required by the plough is given by \(F = 1500 + 20M\) newtons, where \(M\) is the soil moisture percentage above the optimum. Determine the soil moisture percentage \(M\).
