Answer:
Mass, M = 1000 kg
Speed, v = 90 km/h = 25 m/s
time, t = 6 sec.

] Ceres is composed of rock and ice and is estimated to comprise approximately one third of the mass of the entire asteroid belt. Ceres is the only object in the asteroid belt known to be rounded by its own gravity (though detailed analysis was required to exclude 4 Vesta).

Answer:
Explanation:
The total charge is distributed over the two objects:
The plate and the rod must have . So the charge transferred from the plate to the rod is:
Number of electrons:
