Answer:
A) True
Explanation:
Researchers have detected numerous jets of gas ejected from poles of young stars and planetary nebulae.
By examining images of hydrogen molecules excited at infrared wavelengths, scientists have been able to see through the gas and dust in the Milky Way, in order to observe the most distant targets. These goals are normally hidden from view and many of them have never been seen before.
The entire study area covers approximately 1,450 times the size of the full moon, or the equivalent of an image of 95 gigapixels. The survey reveals jets emanating from proto-stars and planetary nebulas, as well as remnants of supernovae, the illuminated edges of vast clouds of gas and dust, and the warm regions that surround massive stars and their associated groups of smaller stars.

Answer:
35.2 ps
Explanation:
Hello!
A US short ton is equal to 2 000 pounds, therefore:
2.25 tons = 4500 pounds
Now lets convert the area of each tire footprint:
1 cm = 0.393701 in
12.5 cm = 4.92126 in
16.5 cm = 6.49607 in
Therefore, the area of the footprint is: 31.9688 in^2
Then, the pressure exerted by the car is given by the weigth devided by the total area, that is 4 times the area of the footprint :
4500 /(4 * 31.9688) psi = 35.1906 psi
Rounding to the first tenth
35.2 psi
