Compute for the scale height of a certain planet's atmosphere (the height the atmosphere would have if its density stayed constant instead of decreasing with altitude.) express your answer in meters. No unit is required for the final answer.
radius of the planet = 6,371 km : density of air = 1.21 kg/m^3
Please answer asap.
You can determine the radius of a planet by measuring the change in the flux coming from the star (i.e. the transit method). If the radius of the planet increases, the overall flux decreases, but what happens to the change in the flux?
Hint: the change in a quantity is represented by the uppercase delta or triangle symbol.
Group of answer choices
- Increases
- Decreases
- Stays constant

One synodic period is required for Earth to be in the same place relative to mars as when it landed. Calculate the synodic period (in years) using the following formula: 1/Psyn = (1/PEarth) - (1/PMars) where PEarth is the sidereal period of the Earth (1 year) and PMars is the sidereal period of Mars. If 3/4 of a Martian year was spent collecting samples and exploring the terrain around the landing site, calculate how long the Mars Robotic Lander expedition took!arrow_forwardDescribe the planet Venus.
