Answer:
Vehicle 1
Explanation:
WE know that a=F/m and since F is the same for all vehicles, it means the higher the mass, the lesser the acceleration and the smaller the mass the higher the acceleration. From the table given, vehicle a has the smallest mass, of 1000 Kg hence it yields the highest acceleration

Answer:
Explanation:
N=Rotor Speed in Revolution per minute(rpm)
for P=4 and N=3600, f comes out to be 120 Hz.
So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz).
The most practical situation is generator having N=3600Hz with 2 Poles.
Hope It will be helpful!!!
