Answer: the radius of the satellite's orbit is r = 8.78×10⁷m
Explanation:
given the time period, T= 3days
converting the time in days to seconds is given as;
time, T=(3*24*60*60) sec
T=259200 sec
from the force relation;
mv²/r = Gm×M/r²
v²=G×M/r ---------------(1)
and
V=2pi×r/T
V²=4×pi²×r²/T²
====>
from equation (1)
, we have
4×pi²×r²/T²=G×M/r
this becomes; 4×pi²×r³/T² = G×M
r³ = G×M×T²/(4pi²)
r³ = 6.67×10⁻¹¹×(5.97×10²⁴)×(259200)²/(4pi²)
==> r=8.78×10⁷m
radius of the orbit, r=8.78×10⁷ m
As the car is moving it indicates that the kinetic energy is being represented. That's why I am pretty sure that this statement is correct! That's all you need to know to solve this. Regards!
According to the Law of Conservation of Charge, the net
charge remains constant. If both things have different charges, upon contact,
they would share the charge equally. In this case, the total charge is -16μC.
The final charge for each ball would be -8 μC.
The best thing to do in this case is to redo the experiment and re record the info, it has to be precise and accurate so you also have to check if your procedure is correct. If the results are both accurate and precise then you have to report your findings to the committee of that specific field. <span />
