F = G(m1 m2)/(r)^2

Let m1 be the mass of Mars
Let m2 be the mass of Deimos.
Therefore, 6m2 is the mass of Phobos.

We know that G, m1, and m2 are just constants.

Phobos:

Fp = G(m1 * 6m2)/(9000000m)^2 = 7 × 10^(-14) * G m1 m2

Deimos

Fd = G(m1 * m2)/(23000000m)^2 = 2 × 10^(-15) * G m1 m2

Mars exerts a stronger gravitational force on Phobos since Fp > Fd

My Everest is the highest mountain on earth.its height is 8.848 km. Convert this height to feet. Write your answer in standard n

Vinvika [58]

Answer: $2.9(10)^{7} ft$

Explanation:

Firstly we need to know that $1 km=3280.84 ft$ , then we cam make the conversion:

$8848 km \frac{3280.84 ft}{1 km}=29,028,872.32 ft$ This is the height of Mount Everest in feet

However, we can express it using scientific notation by counting to the left the decimal spaces:

$29,028,872.32 ft \approx 2.9(10)^{7} ft$

State Boyle's, Charles's, and Gay-Lussac's laws using sentences, then equations

dimaraw [331]

Explanation:

1. Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto \frac{1}{V}$ (At constant temperature and number of moles)

$P_1\times {V_1}=P_2\times V_2$

2. Charles' Law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

3. Gay Lussac's Law states that tempertaure is directly proportional to the pressure of the gas at constant volume and number of moles of gas

$P\propto T$ (At constant volume and number of moles)

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

Answer : The final volume of gas will be, 26.3 mL

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 0.974 atm

$P_2$ = final pressure of gas = 0.993 atm

$V_1$ = initial volume of gas = 27.5 mL

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $22.0^oC=273+22.0=295K$

$T_2$ = final temperature of gas = $15.0^oC=273+15.0=288K$

Now put all the given values in the above equation, we get:

$\frac{0.974 atm\times 27.5 mL}{295K}=\frac{0.993 atm\times V_2}{288K}$

$V_2=26.3mL$

Therefore, the final volume of gas will be, 26.3 mL
