Answer:
0.3 N
Explanation:
i = 400 A
B = 30 x 10^-6 T
L = 25 m
Force due the current carrying conductor placed in a magnetic field
F = B i L SinФ
where, Ф be the angle between length vector and magnetic field vector
F = 30 x 10^-6 x 400 x 25 = 0.3 N
current . . . flow of electric charges
voltage . . . stored potential energy at the source of a circuit
resistance . . . opposition to the flow of electric current

The law of reflection states that the angle of incidence is equal to the angle of reflection.
Explanation:
Intertia of an object is defined as its tendency to remain in the state or rest or in state of uniform motion. It is basically the measure of mass of an object. The greater the mass of an object, greater will be its tendency to change its state of motion or state or rest. Also, lesser the mass of the object, lesser will be its tendency to change its state of motion or state of rest.
In this problem, car A has a mass of 95 kg and car B has a mass of 110 kg. Car B has more mass than car A, it will have more inertia than car A.
Hence, inertia of car B is 15 more than the inertia of car A.
Useful output = (efficiency) x (input energy)
(1000 J) = (0.12) x (input energy)
Divide each side
by 0.12 : 1,000 J / 0.12 = input energy
Input energy = (8,333 and 1/3) J
