(10%) Problem 2: The frequency range for AM radio is 540 to 1600 kHz. The frequency range for FM radio is 88.0 to 108 MHz.
Dominik [7]

188m - 556m is the wavelength range for AM radio.

2.77 - 3.40m is the wavelength range for FM radio.

1) For AM radio

f(max) = 1600 × 10³ Hz

f(min) = 540 ×10³Hz

c = fλ

λ = c/f where,

c = speed of light

f = frequency

λ= wavelength

So,

λ(min) = 3 × 10^{8} / 1600 × 10³ = 188 m

λ(max) = 3 × 10⁸/540 ×10³ = 556 m

So wavelength range of AM radio is 188 m - 556m

2) For FM radio

f(max) = 108 × 10⁶ Hz

f(min) = 88 × 10⁶ Hz

λ(min)  = 3 × 10⁸ / 108 × 10⁶ = 2.77 m

λ(max) = 3 × 10⁸ / 88 × 10⁶ = 3.40 m

So wavelength range of FM radio is 2.77m - 3.40m

Approximately how much heat energy does it take to raise 1 kg of water by 1 k?
Sidana [21]

Answer:

4186 Joules

Explanation:

The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,

C_s = \frac{Q}{m \Delta T}

where

Q is the amiunt of heat needed

m = 1 kg is the mass

\Delta T = 1 K

is the variation of temperature of the substance

For water, the specific heat capacity is 4186 J/(kg K). This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.

In your own words explain why the thickness and length of a wire could effect the flow of electrons​
agasfer [191]

Answer:

(you can use my exact words) The length and thickness would make it so that the electrons move differently than they would a shorter and thinner wire because with the wire being longer the electrons would have a longer trip and with the wire being thicker the electrons would be more spread out and move be able to move more freely
