The mixture of HFc-134a with high concentration of air at raised pressure can become combustible in presence of a ignition source, that is oxygen enriched environment.Thus at high pressure in a mobile air condition led to combustible of HFC-134a.
If everyone died then the too people were not on the plane they were near by when the plane crashed and were not onbard.
Answer:
<h3>This tends not to happen, because atoms are composed of charged particles that interact at a distance. ... Since the electrons are around the outside of the atom, those are the things that first interact, and as they have the same charge, they repel one another.</h3>
A. The electrons from atom repel each other
Answer:
Distance moved = 42 meters
Mag and Dir = 10 meters northward
Explanation:
Distance is total distance traveled which = 22+16+4 = 42 meters
Displacement is the amount of distance moved from the start point to the end point straight line so our equation for the magnitude is 22-16+4 = 10 meters. Then the direction is northward from the start point. This answer would also be a vector because it has a magnitude and direction.
Doppler Effect is required to solve the problem. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other. The general formula of observed frequency, due to Doppler's effect is as follows,
= Frequency observed by observer
v = Velocity of Sound
= Velocity of observer
= Velocity of source
= Frequency of source
PART A) Replacing our values we have that,
PART B) Here the same procedure is performed but this time repeated in the opposite direction.
