So to solve this problem, we must convert units and then cancel units simultaneously:

Therefore we know that the distance that light travels in one year is
inches.
Answer:
d = 
Explanation:
This comes from diffrection pattern equation used to locate fringe pattern, i will explain every variable in it here.
n = order of fringe = 0 1 2 3 .. and negative integars as well.
d is sacing between slits.
Theta = angle at which light-Ray is directed towards fringe.
It appears that the distance between consectice fringes would same as the distance between two slits 'd'.
therefore calculating that distance should give us the distance between two fringe patters.
Note we don't use transversal seperation distance here.
Answer:
It will take 0.01 s or 10 ms
Solution:
As per the question:
Length of the packet, L = 1,000 bytes = 
Distance, d = 2500 km = 
Speed of propagation, s = 
Transmission rate, R = 2 Mbps
Now,
Propagation time, t can be calculated as:

t = 10 ms
- In general, propagation time, t is given by:

- No, this delay is independent of the length of the packet.
- No, this delay is independent of the rate of transmission.
