Equation of movement is
y(x) = x * tg (a) -

where y is y-coordinate, x - x coordinate, u - your initial speed, a = angle above horizon.
differentiate it to get dy/dx (speed)
Answer:
magnetic flux linkage includes number of turns, N while magnetic flux has no N
Since number of turns are not significant to units, they become similar.
<span>Sure, Just change the 2 sec. into hrs. Since 1 hour = 3600 sec. then you can divide 2/3600 = 1/1800 hrs.
Distance in kilometers = (Speed in km/hr * time in hrs)
= 50*(1/1800)*1000 in meters
= 27.77 meters</span>
20/45=0.4*100= 44.4 so the answer is..................................................
Answer: 44.4%
