Answer:
The passenger aircraft would take 10.542 years to reach the Sun from the Earth.
The passenger aircraft would take
years to reach the gallactic center.
Explanation:
The distance to the sun from the Earth is approximately equal to
, if the passenger travels at constant speed, then the time needed to reach the sun is calculated by the following kinematic formula:
(1)
Where:
- Travelled distance, measured in kilometers.
- Speed of the passenger aircraft, measured in kilometers per second.
- Travelling time, measured in seconds.
If we know that
and
, then the travelling time is:
![\Delta t = \frac{1.496\times 10^{8}\,km}{0.45\,\frac{km}{h} }](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B1.496%5Ctimes%2010%5E%7B8%7D%5C%2Ckm%7D%7B0.45%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D%20%7D)

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.
The distance between the Earth and the galactic center is approximately equal to
. If the passenger travels at constant speed and if we know that
and
, then the travelling time is:
![\Delta t = \frac{2.460\times 10^{17}\,km}{0.45\,\frac{km}{s} }](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B2.460%5Ctimes%2010%5E%7B17%7D%5C%2Ckm%7D%7B0.45%5C%2C%5Cfrac%7Bkm%7D%7Bs%7D%20%7D)

The passenger aircraft would take
years to reach the gallactic center.
Answer:
High tide will be higher than it is now and neap tides will be shallower
Explanation:
Answer:
A. I<u>t take up 71% of the earth's crust</u>.
Explanation:
- The oceanic crust makes about more than 70 percent of the oceanic landmass, having a thickness of 25 to 70 kilometers thick. Its the oldest of the crust on earth. Having an average density of 2,7 g/cm, primarily being composed of denser rocks like basalt and gabbro from below.
- Mostly it's basaltic, from here all sorts of rocks are recycled to the outer land surface of the earth. Accounting for nearly 60% of the global slab of plates.
- Apart from this, the seafloor is covered with volcanic necks, trenches and deep-seated volcanoes that produce magma and the oceanic floor is composed of layers of rocks that date back to the various epi, meso, bathy, and abyssopelagic divisions.
in my opinion I think the answer is A. It remains fertile for decades and will yield large crops. i might be wrong sorry
