The correct answer should be D. copper
Nickel, cobalt, and iron, produce magnetic fields when electrified while copper does not.
400 km - 300 km = 100 km, since the dog stopped only 100 km away from where he had originally started out.
Answer: a) C decreases; b) Q stays the same; c) E is the same
d) ΔV increase
Explanation: In order to explain this problem we have to consider the following:
C=εoA/d where A and d are the area and the separation of the plates, respectively.
Increasing d, produces a decrease of C.
Q remain constant becasuse the plates are charges and the wire are isoloted each other.
We also know that ΔV=E*d where E is electric field between the plates.
And E= Q/εo*A ( a constant between the plates)
As we can see from above, ΔV depends directely of the d so if d increase ΔV also increase. To do that we have to do work on the system.
Answer:
The angular frequency is the coil rotating is 1.9 rad/s.
Explanation:
Given that,
Number of turns = 600
Radius = 15 cm
Magnetic field = 0.020 T
Maximum induced emf = 1.6 V
We need to calculate the angular frequency is the coil rotating
Using formula emf
When induced emf is maximum so 
will be 1.
Where, N = number of turns
A = area
B = magnetic field
Put the value into the formula
Hence, The angular frequency is the coil rotating is 1.9 rad/s.
Answer:
1.A.) woman whose father was a United States citizen
2. A.) demonstrate the ability to read, write, and speak English
C.) pass a citizenship exam that tests one’s understanding of U.S. civics
D.) lawfully reside in the United States for at least five years
Explanation:
When you are born to at least one whom was a U.S citizen at time of birth then you automatically acquire U.S citizenship through acquisition process.This is not affected by the place of your birth maybe in the U.S or in another country.This claim is also true for foreign born adoptees to the United States.
A foreign born individual who is not automatically entitled to the United States citizenship can obtain this state through the naturalization procedure.It involves fulfilling the naturalization requirements such as being of the age 18 and above, being a permanent residence of the U.S for at least 5 years, being able to read, write and speak English, having basic knowledge of the U.S civics understanding, and but not least to being of good moral character.
