<em>EVERYWHERE !</em>

I know this because no matter where in my house I take my little AM/FM radio or my smart phone or my laptop, I can pick up AM or FM stations, or make cellphone calls, or connect to our WiFi and watch movies or log onto Brainly.

I have my exam monday I need some help!
Lana71 [14]

Answer:

Explanation:

If the passage of the waves is one crest every 2.5 seconds, then that is the frequency of the wave, f.

The distance between the 2 crests (or troughs) is the wavelength, λ.

We want the velocity of this wave. The equation that relates these 3 things is

f=\frac{v}{\lambda} and filling in:

2.5=\frac{v}{2.0} so

v = 2.5(2.0) and

v = 5.0 m/s

In space movies, spacecrafts explode and oxygen is needed for a fire to start. Why is it wrong? What would really happen?
Triss [41]

Answer:

Hey

The reason these "space movies" are wrong is because objects in "space" (not in a "space" craft) can't catch on fire because there is no air in "space".
