Answer:
Proxima Centuri is 9 orders of magnitude further from New York compared to Perth
Explanation:
Distance of Proxima Centuri to New York = 4 × 10^16 meters
Distance of Proxima Centuri to Perth = 11000 miles
Since 1 mile = 1609 meters, distance to Perth in meters = 11000 × 1609
Distance to Perth = 17699000 = 1.7699 × 10^7 meters
Order of magnitude of the distances of Proxima Centuri to New York and Perth = 10^16/10^7
Order of magnitude = 10^9
Therefore, Proxima Centuri is 9 orders of magnitude further from New York compared to Perth.
A. True would be the best answer
Explanation:
subscript is K
superscript is ^
subscript K means a unit of temperature like F or C
superscript ^ means to the power of
So all together it means to the power of 40 K
