The table shows data for the planet Uranus. A 2 column table with 4 rows. The first column is labeled Quantity with entries, Esc

ape velocity in kilometers per second, Gravitational acceleration in meters per second squared, Orbital velocity in kilometers per second, Length of day in hours. The second column is labeled Value with entries, 21.3, 8.7, 6.8, 17.2. To the nearest whole number, how much would a 25.0 kg rock weigh on Uranus?To the nearest whole number, how much would a 25.0 kg rock weigh on Uranus?

4 0

Answer:

The answer is 218

Explanation:

Weight = mass * gravitational acceleration

weight is represented by F

F = 25kg (8.7)

(I'm pretty sure that you don't have to include the meters per second/per second thing)

Air escaping out from an air hose at a gas station always feels cool. Why? ​
kati45 [8]

Answer:

The air is contained at a high pressure in the tube. When it escapes from a small orifice, it suddenly expands. A large amount of its heat is absorbed in the process of expansion resulting in considerable fall in its temperature. This is why the escaping air feels cold.

Find the values of the root mean square translational speed v, molecules in gaseous diatomic oxygen (O2), gaseous carbon dioxide
frez [133]

Answer:

539.19 m/s , 459.83 m/s , 2156.78 m/s

Explanation:

The formula for the rms speed is given by

v_{rms}=\sqrt{\frac{3RT}{M}}

Where, R be the gas constant, T be the absolute temperature and M be the molecular mass of the gas

R = 8.314 in SI units

T = 100°C = 100 + 273 = 373 K

For Oxygen:

M = 32 g = 0.032 kg

v_{rms}=\sqrt{\frac{3\times 8.314\times 373}{0.032}}

vrms = 539.19 m/s

For carbon di oxide:

M = 44 g = 0.044 kg

v_{rms}=\sqrt{\frac{3\times 8.314\times 373}{0.044}}

vrms = 459.83 m/s

For hydrogen:

M = 2 g = 0.002 kg

v_{rms}=\sqrt{\frac{3\times 8.314\times 373}{0.002}}

vrms = 2156.78 m/s
