Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts.

Does the EMF (electromagnetic field) it generates pose any health threat to the household? Thanks

I had a test earlier today and there was this question that I just could not figure out. Question:

All of the following are examples of post-translational modification except:

a. joining of two or more subunits to form a quaternary structure
b. attachment of sugars, lipids or phosphate groups
c. division of the chain into sections
d. removal of primers


I do not want to have to wait until next week to find out the answer to the question, so could someone help me out please? Thanks.

I was trying to research on naming a star, but I found a few places. Is there one that is the best, or even just one that is the only. I am a little iffy, because I wouldn't think that multiple places could have that control.

3. [P15-7] Oppositely charged parallel plates are separated by 5.33 mm. A potential difference of 600 V exists between the plates. (a) What is the magnitude of the electric field between the plates? (b) What is the magnitude of the force on an electron between the plates? (c) How much work must be done on the electron to move it to the negative plate if it is initially positioned 2.90 mm from the positive plate?



4. [A15-1b] Rub an inflated balloon with a piece of wool cloth and place the balloon near a fine stream of water falling from a faucet. The stream of water will deflect toward the balloon. Why? Vary the distance between the balloon and the stream, and observe the displacement of the water stream for different distances. What is the relationship between the displacement of the stream and the distance of separation?
