Answer: The correct option is,

A. 5.0\times 10^3

Explanation:

Given expression,

(2.5\times 10^{10})\times (2.0\times 10^{-7})

=2.5\times 2.0\times 10^{10-7}

( By using product property of exponent i.e. a^m\times a^n = a^{m+n} )

=5.0\times 10^3

atmospheric pressure at elevations of 8000 feet averages about 0.72 atmospheres. Would a cabin pressurized at 500 mm hg meet fed
NeTakaya

Answer:

Yes, but it must be kept at that value and do not let it to decrease more.

Explanation:

Hello.

In this case, in order to substantiate whether the cabin meet the federal standards, we need to convert the 500 mmHg to atm and compare the result with 0.72 atm by knowing that 1 atm equals 760 mmHg:

500mmHg*\frac{1atm}{760mmHg} \\\\=0.66atm

Thus, since 0.66 atm is 0.06 atm away from the federal standard we can infer that it may meet the federal standard, however, it would not be recommended to let the pressure decrease more than that.
