Cell phone conversations are transmitted by high-frequency radio waves. Suppose the signal has wavelength 36.5 cm while travelin
tia_tia [17]

Answer:

f=8.219*10^{8}Hz

Explanation:

We are going to use the formula  v=fλ

Where v= velocity of radio waves

f= frequency

λ= wavelength of wave

  • radio waves are electromagnetic waves and as such they have the speed of light which is 3*10^{8}m/s.
  • also when a wave travels from one medium to another, the wavelength changes while the frequency remains the same.
  • calculating for the frequency of the wave in air also gives us the frequency in the window glass.

f=\frac{v}{λ}

v=3*10^{8}m/s.

λ=36.5 cm = 36.5/100= 0.365m

f=\frac{3*10^{8}m/s.}{0.365m}

f=8.219*10^{8}Hz

Find the value of 15.0 N in pounds. Use the conversions 1slug=14.59kg and 1ft=0.3048m. Express your answer in pounds to three si
kotykmax [81]

Given the equivalent value to convert the units from kilograms to slug and feet to meters, we will proceed to define the equivalence of the 'Newton' in simplified units, that is,

1N=1kg\cdot m\cdot s^{-2}

Then,

15.0N=15.0kg\cdot m\cdot s^{-2}

Converting this value to British units we have that

15N = 15.0kg\cdot m\cdot s^{-2} (\frac{1slug}{14.59kg})(\frac{1ft}{0.3048m})

15N = 3.37 slug \cdot ft \cdot s^{-2} (\frac{1 lb \cdot ft^{-1}}{1slug})

15N =3.37lb

Therefore the value of 15.0 N in pounds is 3.37 lb.

Nat2105 [25]

Answer:

Galileo is one of the most revolutionary scientists in terms of the novelty of his ideas.

He made great advances in the laws of motion and astronomical matters, as well as the creation of telescopes, making the first observations of the Moon, Venus and Jupiter satellites.

He supported Copernicus's idea that the earth revolves around the sun, which was a controversial idea for his time, and the reason why his books were banned because the idea that the earth was not the center of the universe was not yet a well received idea.

For his ideas he was persecuted by the Inquisition and accused of heresy, but he was a proud man and stayed true to his ideas .
