The earth falls freely in a gravitational field that is largely due to the moon7 . Moreover, the earth is surrounded by a sphere of liquid called the ocean. Based on your answers to problem 1, do you expect the ocean to be perfectly round? Draw a picture of its shape.
The spactime diagram below is drawn in the reference frame of a small lab sitting on the earth (which experience a newtonian gravitational field of g=10m/s^2 ) which of the worldline shown below has the greatest proper time? Why the answer you choose is correct
