The answer is true, is called Thermal pollotion:).
Answer:
Remain at 12 noon - you would be traveling with the wavefront that reads 12 noon:
Also Δt' = Δt / (1 - β^2)^1/2
Where Δt is the proper time interval (at the clock)
Since the denominator is zero the measured time interval is also infinite and the time between "ticks" is infinite
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 :)
Four different things can happen when light hits an object
<span>The waves can be reflected or scattered off the object. </span>
<span>The waves can be absorbed by the object. </span>
<span>The waves can be refracted through the object. </span>
<span>The waves can pass through the object with no effect.</span>
