Consider two hosts A andB, connected by a single link of rate R bps. suppose that the two hosts are separated by mmeters, and supose the propagation speed along the link is s meters/sec. Host A is to send a packet ofsize L bits to Host B. a. Express the propagation delay d(prop) interms of L and R.
b. Determine the trnasmission time of the packet d(trans) in termsof L and R.
c. Ignoring processing and queing delays obtain an expression forthe end to end delay.
d. Supose Host A begins to transmit packet at time t=0 . At timet=d(trans) where is the last bit of the packet.
e. Suppose d(prop)is greater than d(trans) . At time t= d(trans)where is the first bit of the packet
f. Suppose d(prop)is less than d(trans) . At time t= d(trans) whereis the first bit of the packet
g. Suppose s=2.5* 10power(8), L=100 bits and R=28 kbps. find thedistance m so tha d(prop) equals d(trans).

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
