Average speed = (distance covered) / (time to cover the distance).
Distance covered = 437 km = 437,000 meters
Time to cover the distance = (7.27 hrs) x (3600 sec/hr) = 26,172 seconds
Average speed = (437,000 meters) / (26,172 seconds)
Average speed = 16.7 m/s
Its just Calcium Flouride because as you can see it is an Ionic bond (Ca is metal and fl is a gas usually)
All the radiation from stars is the result of nuclear fusion in their cores.
Answer:
Violet has a higher frequency (approximately 7.5×1014 Hz 7.5 × 10 14 Hz ) than red light (approximately 4.3×1014 Hz 4.3 × 10 14 Hz ). Since the speed of both waves is the same, we infer that violet has a shorter wavelength (400 nm ) than red (700 nm ).
Explanation:
hope it helps this took a lot of my time please mark brainlets!
3 times 6= 18. The average speed is 19 mph.
hope this helps!
