Suppose a 1 Gbps point-to-point link is being set up between the Earth and a new lunar colony. The distance from the moon to Ear
1 answer:
Answer:
The time required to send the data from Earth to Moon will be 1.28s while for a two way communication, to send it back to the earth, it will take double time i.e. <em>RTT = 2.56s </em>
Explanation:
Distance between Earth and Moon = 385,000 km = 3.85 x 10⁸m
Speed of data travel = speed of light ≈ 3 x 10⁸m/s
As, v=d/t
t=d/v
t=1.28s
RTT = Double of single way time taken = 2x1.28
<em><u>RTT=2.56s</u></em>

(a)
The radius of the trajectory of a charged particle moving perpendicular to a magnetic field is given by
where
m is the mass of the particle
q is its charge
v is its velocity
B is the strength of the magnetic field
In this problem, we have:
B = 1.20 T
r = 0.231 m
Solving for q, we find its charge:
(b) 3
The charge of an electron is
While the charge of this oxygen ion is
So, the ratio between the two charges is
(c) Because an ion is an atom that has gained/lost an integer number of electrons
An ion is an atom that has gained/lost an integer number of electrons. In this particular case, we see that the charge of the oxygen ion is 3 times that of the electron: this means that the ion has gained/lost exactly 3 electrons.
The ratio found in part (b) cannot be a fraction, because that would mean that the atom has gained/lost a fractional number of electrons: but this is impossible, since the electron is a fundamental particle so it cannot be "divided", therefore the ratio must be an integer.
