Zero gauge wire has a diameter of 0.32in and can carry a sustained current of 150A safely. What is the magnetic field a distance

5cm from the center of a long straight segment of zero gauge wire carrying a current of 150A? This would be the field experienced by a bird sitting on the wire. Select One of the Following:
(a) 1.2 × 10−2T
(b) 1.9 × 10−3T
(c) 3.0 × 10−4T
(d) 6.0 × 10−4T
(e) 1.0 × 10−6T

Answer: d) 6*10^-4 T

Explanation: In order to explain this problem we have to use the Ampere law to calculate the magnetic field, which is given by:

∫B*dl=μo*I  then

B=μo*I/(2*π*r)  where r and I are the distance to the wire and the current in the wire. μo is equal 4*π*10^-7 Wb/A*m

Finally, we have:

B=4*π*10^-7*150/(2*π*0.05)=6*10^-4 T

Correct the sentence below to reflect an “I” statement. 
Anarel [89]
The word “you” shouldn’t be used, and I learned the I statement to have your feelings stated, then when, then because, and finally a want. So, to correct this, an appropriate statement would be “ I feel misunderstood when I am treated like a child because my curfew is set for 9:00 pm on the weekends and I want to be seen as your equal and as though you are not superior to me. You can use the word “you” after stating you want something out of the other person.

Which of these has the most inertia?
VashaNatasha [74]

Answer:

A. a parked bus

Explanation:

Because a parked bus probably has the most mass out of these 4 and as we know, mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
