Answer:
The magnitude of the lift generated by the wings of the airplane is 130,340 N.
Explanation:
Given;
mass of the airplane, m = 13,300 kg
speed of the airplane, v = 560 km/h = 155.56 m/s
The magnitude of the lift generated by the wings of the airplane is calculated as;
Therefore, the magnitude of the lift generated by the wings of the airplane is 130,340 N.
For this case you must first know the definition of density. D = m / v where, m: mass v: volume. You can then write the following hypothesis: IF you know two physical characteristics of an object then you can determine the density. First weigh the object, THEN measure its volume BECAUSE the density is the quotient between the mass and the volume of an object.
Longitude was. Determining longitude requires knowing the exact time of day, which was difficult prior to modern clocks. The source book below tells the story of Englishman John Harrison's life-long pursuit of building a reliable clock and its importance to navigation.
Work is = to force*displacement which give W=F*d so if 0 force is put on an object the W= 0*d = 0 work, so a is out. for b if force is put on the object but it does not move then W=F*0 (no displacement)= 0 so if there is no movement then no work is done so b is out. for D since W=F*d also says no force is put on the object so W=0*d which would equal 0 work so D is also out. but for c W=F*d and if we assume that F is not = to 0 and d is not equal to 0 then the equation W=F*d would give a number other than 0 so only c will result in a nonzero value for work. in all other cases no work is done. As a side note if a force is applied to an object and the object goes around the world and ends up and the same place that it started then since Work is equal to force * displacement there will still end up with no work being done since W=F*0=0 work (since the object ended up in the same place it started even though it moved the displacement is still 0, so work done will still be 0.
