Using the same math we used from the parallax lab, we can find the relationship between the linear size of the circle of light, the linear distance to the circle of light and the angular size of the circle of light. Which of the following shows that relationship?

Using the equation you chose from above, solve for r and find the area of the circle of light.

Calculate the amount of gravity the earth applies to the international space station, If the mass of the ISS is 419,725 kg, the mass of the earth is 5.9736 x 10^24 kg, The radius of the earth is 6,378.1km and the ISS orbits at 408 km. Pay attention to units and significant figures, the Gravitational constant G = 6.674×10−11 m3⋅kg−1⋅s−2.

If you calculate the amount of gravity the earth applies to the international space station, If the mass of the ISS is 419,725 kg, the mass of the earth is 5.9736 x 10^24 kg, The radius of the earth is 6,378.1km and the ISS orbits at 408 km. How many significant figures would you have to use?

1

The acceleration due to gravity on the surface of the earth is about 9.8 m/s^2. The acceleration due to gravity on the ISS is about 8.7 m/s^2. Why does all the footage of the ISS look like there is no gravity?
