NEED IT ASAP PLEASE 3 examples of how we use physics in our everyday life. Please explain throughly.
Flauer [41]

Answer:

  1. Alarm Clock. The buzzing sound of an alarm clock helps you wake up in the morning as per your schedule. The sound is something that you can’t see, but hear or experience.
  2. Cell Phones Cellphones have become like Oxygen gas in modern social life. Hardly, anyone would have been untouched by the effects of a cell phone. Whether conveying any urgent message or doing incessant gossips, cellphones are everywhere. But do you know how does a cell phone work? It works on the principle of electricity and the electromagnetic spectrum, undulating patterns of electricity and magnetism.
  3. Walking.Now, when you get ready for your office/school, whatever medium of commutation is, you certainly have to walk up to a certain distance. You can easily walk is just because of Physics. While you have a walk in a park or on a tar road, you have a good grip without slipping because of a sort of roughness or resistance between the soles of your shoes and the surface of the road.

Explanation:

physical is related to things perceived through the senses as opposed to the mind; tangible or concrete.

11Alexandr11 [23.1K]

Answer:

Answered

Explanation:

Part A

According to Faraday's law the induced emf in coil is equal to negative of its rate of change of magnetic flux time the number of turns in the coil.

\epsilon = -N\frac{d\phi}{dt}= -N\Delta\frac{BA}{\Delta t}

When an emf generated by a change of magnetic flux, produced current of whose magnetic field opposes the change  which produces it.

By the above equation the correct options are 1,2 and 4

Part B

Large signals of  frequency of 60Hz are measured by osciloscope.

Hence the correct option is part 1.
