Use 384400 km for the distance between the earth and the moon, and 5.972 1024 kg for the mass of the earth. Help on how to format answers: units F =Assume the data collected were as follows: (where the force in Newtons is computed by converting the mass to kilograms and then multiplying by the gravitational acceleration 9.8 m/s²) m (grams) Force (Newtons) x (cm) (measured) (computed) (measured) 1000 9.8 1 2000 19.6 1.5 3000 29.4 2.1 4000 39.2 2.4 5000 49 3 Make a plot of force vs. stretch distance x. This means force should be on the vertical axis. Since Fgravity = -Fspring (they are in opposite directions) and Fspring = -kx, then: Fgravity = kx This means the slope of your graph is the spring constant k. Fill in your value for k (measured in Newtons/cm)
- Rick is an Aerospace Engineer at NASA’s Jet Propulsions Laboratory (JPL), and is designing the next mission to Pluto called “New Horizons 2: The Sequel". This time Rick plans to study Pluto's largest moon Charon. Charon has a mass of 1.586 ×1021 kg and a mean radius of 606 km, and might have a nitrogenous atmosphere (N2) just like Pluto. If, for a massive object to have an atmosphere its escape speed must be 12 times greater than the root-mean- square (rms) velocity of the gas (otherwise the gas will slowly leak away over time), what is the maximum temperature that Charon can have and still have a nitrogenous atmosphere? [Charon has a temperature of -281 °C = 55 K, day or night.]Imagine a particular exoplanet covered in an ocean of liquid ethane.
