F=7,5 N
m = 3kg
F=m.a
7,5=3.a
a=7,5/3
a=2,5 m/s^2
Vo = 65cm/s -> 0,65m/s
Vt = 15m/s
t..?
Vt=Vo+a.t
15 = 0,65 + 2,5.t
14,35=2,5.t
t=5,74 secon
If the Earth didn't rotate, winds would travel either North or South due to differences in temperature and pressure at different latitudes.
The modern-day generator works on the principle of electromagnetic induction discovered by Michael Faraday in 1831-32. Faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
