You need to convert the 4 hr 7 min 29 s all to the same unit to start off with, the best thing to do usually is to convert to the smallest unit so we convert to seconds:
29s = 29s, no need to change anything there
7min = 7 X 60s = 420s
4h = 4 X 60min = 240min, 240 X 60s = 14,400s
Now that we've converted all the time units to the same unit (seconds), we add them together:
29 + 420 + 14,400 = 14,849s
Generally when we talk about speed and are using seconds as our unit for time, we express speed in m/s (metres per second), so now we convert the kilometres to metres:
1 km = 1000 m, so 42.2 km = 42.2 X 1000 = 42,200m
Finally, we can use our formula:
42,200 / 14,849 = 2.841942218 m/s
(I kind of rushed the calculations a little bit so that figure may not be 100% accurate, but the method is definitely correct)
Hope this helped :)
Answer:
ice crystals in air
Explanation:
Mists structure when the undetectable water fume noticeable all around gathers into obvious water beads or ice gems. For this to occur, the bundle of air must be immersed, for example unfit to hold all the water it contains in fume structure, so it begins to consolidate into a fluid or strong structure.(hopes this helps)
Answer:
white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density
If they're both the same product then they both have the same density. Density only depends on the substance. It doesn't depend on how much of it you have.
