I use exclamation points (!) with relative frequency! I used two there! Oh, look, three! (and four) Okay so I had a little fun with the fist line but, all kidding aside I use exclamation points frequently. I typically …

Apr 24, 2018 · The Doppler Effect is the apparent change in the frequency of a wave due to the relative motion between the source and the observer. When a emergency vehicle speeds by you, the pitch of …

A girl is riding her bike down the street at a speed of 3.5m/s [E] when she hears a fire truck with a siren emitting a sound with a frequency of 425Hz. The girl detects a frequency of 475Hz. The air …

The idea here is that you need to use two very famous equations, the Einstein equation, which relates mass and energy E = m⋅ c2 , where c - the speed of light in vacuum, approximately equal to 3 ⋅ 108m …
