What You Need:
Metal spoon
30 inches of kite string (40 inches for an adult)
What You Do:
Tie the handle of the spoon at the midpoint of the string.
Wrap the ends of the string around your index fingers (pointer fingers)
Place your fingers in your ears.
Lean over so that spoon hangs freely and swing the spoon so it taps against a door.
Hit the door again, this time harder.
<span>                              and you can hear it as a bell ( may be church bell sometimes )</span>

Need help with physics electric question!❤️
LUCKY_DIMON [66]

The output voltage is 10 times the input voltage.

So the output coil has 10 times as many turns as the input coil has.

That's how transformers work.

Complicated, huh !

10 times 1,000 turns = <em>10,000 turns</em>

Answer:

A solenoid field is increased with the increase in the current flow through the coil.

Explanation:

A solenoid is a current carrying coil with a significant number of loops. It works like an electromagnet inside which, a uniform and strong magnetic field is created. The magnetic field outside the solenoid field is nearly zero but not exactly zero.

While experimenting with the solenoid, scientists came to know that the magnetic field generated by the solenoid increases with the increase in the current, flowing through the solenoid.

The magnetic field works strongly around the arena of coil. The field changes its direction only near the ends and gets weak. Else its uniform throughout the loops.

The magnetic field inside the solenoid can be formulated as,

B=\mu n I

Where,

B = Magnetic field generated by the solenoid

\mu = Constant

I = Current flowing through the loops of the solenoid

consider a wave approaching a barrier with a small hole. what change is the wave likely to undergo as it passes through the hole
Nimfa-mama [501]

Answer: The correct answer is Diffraction.

Explanation:

Diffraction is the phenomenon in which a beam of light will get bend when it passes through a narrow aperture. It is accompanied by the interference between the wave form produced.

Consider a wave approaching a barrier with a small hole. The diffraction will occur when the wave passes through the hole. There is a bending of light as it passes through the edge of the object or through the hole.

The amount of bending light depends on the relative size of wavelength of the light in comparison to the size of the aperture.

Therefore, the correct answer is Diffraction.
