If you are traveling 98 km in 2h you are traveling 49 km/h (98/2=49).
To calculate how many kilometers you will travel in 3 hours, multiply 49 (the number of kilometers) times 3 (the number of hours) and you get 147 kilometers.

Hope that helps.

The generator at a power plant produces AC at 20,000 V. A transformer steps this up to 355,000 V for transmission over power lin
Masja [62]

Answer:

Number of coil in the output is 39938

Explanation:

We have given a step up transformer

Input voltage of transformer, that is primary voltage v_p=20000volt

Output voltage, that is secondary voltage v_s=355000volt

Number of turns in primary N_p=2250

For transformer we know that \frac{V_p}{V_s}=\frac{N_p}{N_s}

\frac{20000}{355000}=\frac{2250}{N_s}

N_s=39937.5

As the number of turns can not be in fraction so number of turns in the output coil is 39938

What is the requirement for a core to be used in an electromagnet?
xxMikexx [17]

D. It must be able to be magnetized

Explanation:

The requirement for a core to be used in an electromagnet is that it must be able to be magnetized.

An electromagnet is a type of magnet produced by electricity.

  • They typically run and produce magnetic fields in the vicinity of electrical currents.
  • These magnets are not permanent magnets.
  • When the electrical current is removed, the magnetic property of the substance is lost.
  • The core of an electromagnet is usually made up of a material that can easily be magnetized in the presence of magnetic fields.
  • Some of the materials used are cobalt, iron, nickel.
