Answer:
c) 100,000 m/s
Explanation:
You need to take the same wave length from the top graph and bottom one, so let's take half a wave length then in the top one that is 0.005, but in the bottom one it's 2000/4 = 500 because they are smaller and there are 4 half waves before you get to 2000, whereas in the top one there is 1 half wave before you get to 0.005 on the graph.
Now use speed = distance / time
speed = 500 / 0.005 = 100 000 m/s
Rarefractions are areas of high pressure and they are spread out
Compressions are areas of low pressure and they are close together
Answer:
17582.4 L
Explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
Since n is constant:
PV / T = PV / T
(1 atm) (6000 L) / (273 K) = (0.3 atm) V / (240 K)
V = 17582.4 L
It is the distance from crest to crest or trough to trough.or between any tow corresponding points on adjacent waves.
Answer:
B. 7.6 km/s
Explanation:
Given:
Speed of the satellite orbiting Earth is, 
In order to convert the speed from miles/hour to km/s, we need to convert miles to km and hour to seconds.
The conversion factors are:
0.62 miles = 1 km
∴ 1 mile = 
1 hour = 3600 s
Now, 17000 miles/hour can be rewritten as:
Therefore, the speed in km/s is 7.6 km/s.
