Many firms develop a formal marketing plan to answer the question: who is your target market and how do you plan to reach them. A marketing plan is a comprehensive document which sets out an organization's overall marketing strategy. A marketing plan will include digital media, print media as well as product development strategies. The marketing plan takes the organization's mission statement and turns it into a practical plan. Its goal is to practically implement the reason for the organization's existance.
Answer:
0.5 A
Explanation:
N = 20, A = 50 cm^2 = 50 x 10^-4 m^2, dB = 6 - 2 = 4 T, dt = 2 s, R = 0.4 ohm
The induced emf is given by
e = - N dФ/dt
Where, dФ/dt is the rate of change of magnetic flux.
Ф = B A
dФ/dt = A dB/dt
so,
e = 20 x 50 x 10^-4 x 4 / 2 = 0.2 V
negative sign shows the direction of magnetic field.
induced current, i = induced emf / resistance = 0.2 / 0.4 = 0.5 A
