- A wind turbine is set up in a farming field, the wind speed vis 5.2 m/s. Assume that the available area for wind to pass through has a radius of R= 38 m and the local air density is p=1.22 kg/m³, and turbine efficiency of n=0.34. How much power can be generated by this wind turbine? Your Answer: Answer unitsThe propellers of a drone require a force of 70 N to lift, at constant speed, a parcel from the ground to a height of 9 m.a) What work has the drone done if we ignore the friction caused by the air on the parcel?b) What force must the propellers apply if there is a friction force of 10 N caused by the surface to lift the parcel at constant speed?Estimate how much work (in joules) is done by gravity when you roll out of bed and fall to the floor.
