This statement is false due to the fact that sound needs a medium like air to travel and vibrate for us to hear it, next since it's in space theres no air to vibrate no air no sound
Answer:
B. <em>Speed</em> is how fast an object is moving: speed = distance/time.
<em>Velocity</em> is the rate at which an object changes position: velocity = displacement/time
Explanation:
<em>Distance</em> is a <em>scalar </em>quantity. It has only <em>magnitude</em>. So, distance/time is also scalar. If you are travelling at 100 km/h, that is your speed, because you could be going in any direction.
Displacement is a <em>vector </em>quantity. It has both <em>magnitude and direction</em> So, displacement/time is also a vector. If you are travelling east at 100 km/h, that is your velocity, because you are stating both your speed and the direction
It would be lithium and Chlorine because they are trying to get 8 valence electrons and 1 valence electron plus 7 valence electrons.
Answer:
8. littoral I hope it helps
Explanation:
The given data is as follows.
= 2.34 kPa = 2.34 \times 1000 Pa = 2340 Pa = 0.0231 atm
= (20 + 273) K = 293 K
= 2537.4 kJ/kg = 2537400 J/kg
= ?, = (40 + 273) K = 313 K
According to Clausius-Clapeyron equation,
=
=
= atm
or, = 18846.45 kPa
Thus, we can conclude that the vapor pressure at is 18846.45 kPa.
