WILL MARK BRAINLIEST!!! Is string a ferromagnetic material?

Physics
1 answer:
Contact [7]3 years ago
4 0

Answer:

See, the string is made of nickel and steel (iron+carbon), materials that are ferromagnetic. That is, a magnet attracts guitar strings. When this ferromagnetic metal vibrates in the magnetic field of the pickup, that disturbs the red field lines which also cross through the coil (not shown).

Is everyone in your class able to hear a quiet sound equally well?
Sergio039 [100]

Answer:

No

Explanation:

Loudness describes how people perceive sound (see loudness). ... If people could hear equally well at all frequencies, the contour lines would be flat because the same measured sound intensity would be perceived to be equally loud regardless of the sound frequency. In fact, people do not hear as well at low frequencies.

At an airport, two business partners both walk at 1.5 m/sm/s from the gate to the main terminal, one on a moving sidewalk and th
Musya8 [376]

Answer:

v=0.8m/s

Explanation:

From the question we are told that

Distance d=1.5m/sm/s

Time  t_1=60s  

Time  t_2=90s  

Generally the  the equation for the distance traveled is mathematically given as

d=vt

d=1.5*90

d=138m

Generally equation for speed of side walk is mathematically given as

d=(v+u)t

v=\frac{d}{t}-u

v=\frac{138}{60}-1.5

v=0.8m/s

What is the wavelength of an fm radio signal that has a frequency of 91.7 mhz?
Digiron [165]

Answer:

The wavelength of the radio wave will be 3.271 m

Explanation:

We have given frequency of the radio signal f=91.7MhZ=91.7\times 10^6Hz

Speed of the light c=3\times 10^8m/sec

We have to find the wavelength of the radio signal

We know that wavelength is given by \lambda =\frac{c}{f}=\frac{3\times 10^8}{91.7\times 10^6}=3.271m

So the wavelength of the radio wave will be 3.271 m
