Change the time flow rate to 1 day (solar day). note the position of the moon and the background stars and click the step time forward button to advance time by 1 solar day. then change the time flow rate to 1 sidereal d. (sidereal day) and watch the moon and stars in the view when you click the step time forward button again, this time to advance time by 1 sidereal day. repeat these steps to decide which of the following statements is not correct. a in 1 sidereal day, the background stars do not appear to move but the moon does. b in a 1 day time step, the background stars and the moon both move. c looking at the time display, a sidereal day is shorter than a normal 'solar' day by about 4 minutes. d in 1 day, the stars and the moon both appear to move in the same direction.

What is the orbital period of a spacecraft in a low orbit near the surface of mars? the radius of mars is 3.4×106m.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
