Answer:

C

Explanation:

Work is the product of force and distance moved in the direction of force . if no distance, no work is done. Holding a heavy object still means no work is done

Explanation:

In the parallel combination, the equivalent resistance is given by :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....

4. When three 150 ohms resistors are connected in parallel, the equivalent is given by :

\dfrac{1}{R}=\dfrac{1}{150}+\dfrac{1}{150}+\dfrac{1}{150}\\\\R=50\ \Omega

5. Three resistors of 20 ohms, 40 ohms and 100 ohms are connected in parallel, So,

\dfrac{1}{R}=\dfrac{1}{20}+\dfrac{1}{40}+\dfrac{1}{100}\\\\=11.76\ \Omega

Hence, this is the required solution.

Assume that the same amount of current passes through the electromagnets shown. Identify which electromagnet is stronger than th
hodyreva [135]

First electromagnet

Explanation:

The first electromagnet is the strongest and it is stronger than the given electromagnet above.

An electromagnet is a temporary magnet made by passing current through a wire wounded round an iron core or metallic core.

  • When current is passed through, the metal becomes magnetic.
  • The strength of the electromagnet depends on the number of coil round the metal core and also the intensity of current passed through it.
  • The higher the number of coils wounded round the metal core, the stronger the electromagnet that will be produced.
  • Also, the higher the intensity of electricity passed through the wire, the stronger it is.
