Problem (25 pts). Without doing any calculation, what is the value of the electric field at the origin O due to the configuration of 4 point charges shown in the Figure below? Justify your answer with 1 short sentence Bonus (Optional) Problem 5 (25 pts). The Figure below shows a thin nonconducting rod of length L-20 em A total charge of Q-8C is spread uniformly along it. What is the electric field vector at the point P which is located...
3. (20 points) The local spatial average of a power delay profile is shown in the following figure. We assume that the coherence bandwidth is approximated by B and the coherence time is estimated using the popular rule of thumb for modern digital communications. Pr(r) -10 dBm -20 dBm -30 dBm 0 5 10 excess delay r rs) If a baseband message with a bit rate R, 400 kbps is modulated by an RF carrier frequency of 5.8 GHz and...
In an IPv4 packet, the value of HLEN is (1010)2 and the value of the full-length field is (005A)16. How many bytes of data are transported by this packet?
ND-OF-CHAPTER QUESTIONS Thought Questions 1. How do you think TCP would handle the problem if an acknowledgment were lost, so that the sender retrans- mitted the unacknowledged TCP seg- ment, therefore causing the receiving transport process to receive the same segment twice? 2-2. a) Compute the minimum number of TCP segments required to open a con- nection, send an HTTP request and response message, and close the con- nection. Justify this number by creating a table showing each message and...
Describe a public health problem (infectious/chronic/social), state a hypothesis and design a simple epidemiologic study to test it. You may choose either a cohort, case-control, or cross-sectional study, but justify why you chose it instead of the other study types. (Write a sufficient amount to demonstrate that you understand the question. For sample calculations, show your work or state the software used.) Describe a public health problem (infectious/chronic/social), state a hypothesis and design a simple epidemiologic study to test it....

c. Use Guass' law to find the magnitude of the electric field at the right end of the cylinder in terms of σ. Show your work. What is the electric field at the left end of the cylinder? Explain your reasoning. Does the electric field near a large sheet of charge depend on the distance from the sheet? Explain, using your results above to justify your answer. Is your answer consistent with the electric field lines ? Explain how you...
