Answer:

O  Transformer

Explanation:

A transformer is a device for increasing or decreasing voltage through electromagnetic induction. It is very used in power transmission where alternating currents can be stepped up or down for house hold usage.

  • Electromagnetic induction is the process of generating current through magnetic fields.
  • It is made up of primary and secondary coils which helps to change voltage in the presence of magnetic filed at the core.
  • A transformer can either be a step up or step down device.

A catamaran with a mass of 5.44×10^3 kg is moving at 12 knots. How much work is required to increase the speed to 16 knots? (One
Andre45 [30]

The work that is required to increase the speed to 16 knots is 14,176.47 Joules

If a catamaran with a mass of 5.44×10^3 kg is moving at 12 knots, hence;

5.44×10^3 kg = 12 knots

For an increased speed to 16knots, we will have:

x = 16knots

Divide both expressions

\frac{5.44 \times 10^3}{x} = \frac{12}{16}\\12x = 16 \times 5.44 \times 10^3\\x = 7.23\times 10^3kg\\

To get the required work done, we will divide the mass by the speed of one knot to have:

w=\frac{7230}{0.51}\\w= 14,176.47Joules

Hence the work that is required to increase the speed to 16 knots is 14,176.47 Joules
