A model aeroplane flies a distance of 140m in 9.5s. Calculate the average speed of the model aeroplane .Give your answer to 2 significant figures.

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

The answer is frictional force

The best description is: . nobody has any idea what q is.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
