Two stationary positive point charges, charge 1 of magnitude 4.00 and charge 2 of magnitude 1.95 , are separated by a distance of 54.0 . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. Part AWhat is the speed of the electron when it is 10.0 from charge 1?Express your answer in meters per second.= _______ m/s
An observer sees two spaceships moving in opposite directions, each at a speed of
relative to the observer. Find the speed of one spaceship relative to the other. (Enter the answer to four significant figures.)__________ c
Question 8Suppose SPT rule is being used in a “dynamic” scheduling problem. There are five jobs A,B,C,D, and E ready to be processed at the present time. The processing times for the five jobs are 1, 9, 7, 2, and 6 days respectively. A new job F will arrive on the 8th day. The processing time for job F is 5 days. On which day (from present time) job F will be completed?Answer
You are a doctor in a hospital, and a patient is experiencing trouble with her skin repairing itself from a cut. The patient is also expecting a child, but the cells in the reproduction development are experiencing malfunction in cell division.
- Describe the stages of each type of cell reproduction process from a normal patient whose body cells can repair themselves and normal cell division during the reproductive development of the unborn baby.
- Explain the disadvantages and advantages of each type of cell division.
- Discuss how the patient experiencing problems with the cells repairing from the cut and the child’s reproduction development malfunctions can alter haploid and diploid cell development.
Tay-Sachs disease (TSD) is an inborn error of metabolism that results in death,
often by the age of 2. You are a genetic counselor interviewing a phenotypically
normal couple who tell you the male had a first f
emale cousin (on his father’s
side) who died from TSD and the female had a maternal uncle with TSD. There
are no other known cases in either of the families, and none of the matings have
been between related individuals. Assume that this trait is very rare
a) Draw the pedigree of the families of this couple, showing the related individuals
b) Calculate the probability that both the female and the male are carriers for TSD

A billiard ball moving to the left at 30 cm/s collides head on with another billiard ball moving to the right at 19 cm/s. The masses of the balls are identical. If the collision is perfectly elastic, what is the velocity of each ball after the impact?
vf, initially at 30 cm/s = cm/s
vf, initially at 19 cm/s = cm/s
Suppose you are travelling to a remote location where you won’t have access to a supply of electricity for a month (30 days). You will be using your laptop computer, which requires an average of 10 watts, for eight hours a day, every day.a.Suppose that to keep your laptop going for the whole month you have the option of taking with you a supply of alkaline batteries, or else to take a direct methanol fuel cell (DMFC) and a supply of methanol.Compare the approximate weight and volume that these two options would impose on your luggage.You should draw on the information in Block 1 Part 1. You may assume that the DMFC weighs 0.5 kg and has a volume of 0.5 l, and you should make other assumptions where necessary. You may also find it helpful to know that the density of methanol is 0.792 kgl–1.Be aware that there are several different ways you can do this calculation, and various sets of data you can use from the module text. Depending on which data you use and how you do the calculation, there are different possible answers. With the answer you give, it is important
1.2 (a). Carefully describe the two distinct situations in polymer soft matter in which the actual chain end to end distance scales as in an ideal random walk. <r2>1/2 = n1/2 l
(b). Recall that in a good solvent the chain adopts the shape of a self-avoiding random walk (SARW). Write down the scaling relationship for a SARW in 1D (be careful here – excluded volume reigns supreme in 1D!) and in 3D.
(d). Explicitly show that a chain that has collapsed into a compact globule having the same density as the pure bulk has a scaling behavior of <r2>1/2 = n1/3 l
Water being diverted during a flood in Helsinki, Finland (latitude 60◦ N) flows along a diversion channel of width 47 m in the south direction at a speed of 3.4 m/s. On which side is the water highest (from the standpoint of a noninertial system) and by how much?
