a gas exerts less pressure when it has a a. smaller volume b. lower temperature c. higher temperature d. two of the above

1 answer:

6 0

The combined gas law is
$\frac{Pressure_{1} *Volume_{1}}{Temperature_{1}} = \frac{Pressure_{2} *Volume_{2}}{Temperature_{2}}$ with 1 and 2 both being anything with pressure, volume, and temperature. Since pressure is on the top and temperature is on the bottom, they are inversely related, meaning that when the temperature gets high the pressure goes low. In addition, since pressure and volume are both on the top, when volume goes down pressure goes down too. Therefore, since A and C are right, D is the correct answer

Answer: By a mechanism that is not fully understood, charges in a thundercloud are separated such that the lower portion of a cloud takes on a negative charge while the upper portion is positive. In addition to the negative charge on the base of the cloud, there are small pockets of positive charge on the base.

1. A satellite (mass = 4.44 x 109 kg) travels in orbit around the Earth at a distance of 1.9 x 10'm above

Nuetrik [128]

Answer:

The force of gravitational attraction between the satellite and Earth is $2.587\times 10^{10}$ newtons.

Explanation:

Statement is incorrect. Correct statement is:

A satellite ( $m = 4.44\times 10^{9}\,kg$ ) travels in orbit around the Earth at a distance of $1.9\times 10^{6}\,m$ above Earth's surface. What is the force of gravitational attraction between the satellite and Earth?

The gravitational force experimented by the satellite ( $F$ ), in newtons, is calculated by Newton's Law of Gravitation, whose equation is defined by following formula:

$F = \frac{G\cdot m \cdot M}{R^{2}}$ (1)

Where:

$G$ - Gravitational constant, in cubic meters per kilogram-square second.

$m$ - Mass of the satellite, in kilograms.

$M$ - Mass of the Earth, in kilograms.

$R$ - Distance of the satellite with respect to the center of the Earth, measured in meters.

If we know that $G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}$ , $m = 4.44\times 10^{9}\,kg$ , $M = 5.972\times 10^{24}\,kg$ and $R = 8.271\times 10^{6}\,m$ , then the force of gravitational attraction between the satellite and Earth is:

$F = 2.587\times 10^{10}\,N$

The force of gravitational attraction between the satellite and Earth is $2.587\times 10^{10}$ newtons.
