Physics
1 answer:
stepan [7]3 years ago
3 0

Answer:

L'ozone est produit à partir du dioxygène, composé de deux atomes d'oxygène(O2). Aux altitudes supérieures à 30 km, le rayonnement solaire possède encore une énergie suffisante pour casser une partie des molécules de dioxygène et libérer les atomes

Radio waves have a _____ frequency and a _____ wavelength.
Semenov [28]

Radio waves have a low frequency and a long wavelength. (A. low; long)

Explanation:

Electromagnetic waves are periodic oscillations of the the electric and the magnetic field in a plane perpendicular to the direction of motion the wave.

All electromagnetic waves travel in a vacuum at the same speed, which is known as the speed of light:

c=3.0\cdot 10^8 m/s

Electromagnetic waves are also divided into 7 different types, according to their wavelength and frequency. From shortest to longest wavelength (and therefore, from highest to lowest frequency), we have:

Gamma rays

X rays

Ultraviolet

Visible light

Infrared radiation

Microwaves

Radio waves

As we can see from the list, radio waves are the waves with lowest frequency and longest wavelength. They are used in telecommunications, satellite communications, and in general in long-distance transmission of signals. So, the correct answer is

Radio waves have a low frequency and a long wavelength.

If an object falls for 4 seconds, how fast is it going when it hits the ground?
MArishka [77]

Acceleration due to gravity is about 9.8 m/s²

So after every second, the speed increase by 9.8 m/s

After 1 second, the object would fall at a speed of 9.8 m/s

After 2 seconds the object would fall at a speed of 19.6 m/s

So after 4 seconds, the object is going to be at a speed of:

9.8 x 4 = 39.2 m/s

-------------------------------------------------

<u>Answer</u>

39.2 m/s
