Answer:

A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field.

How can students earn a GED
ElenaW [278]

Answer:

How Can You Earn Your GED?

  • You must be at least 16 years old to take the GED Test, and you must not be enrolled in high school. ...
  • You must pass all four subject tests in the GED battery of tests, which means scoring at least a 145 on each test (New Jersey requires a score of at least 150 to pass).

>Rules

You must be at least 16 years old to take the GED Test, and you must not be enrolled in high school. You should also meet state eligibility requirements for the amount of time you've been out of high school. In some states, you have to be out of high school for at least 60 consecutive days before you're allowed to take the test. Contact the program administrator in your state for more details.

You must pass all four subject tests in the GED battery of tests, which means scoring at least a 145 on each test (New Jersey requires a score of at least 150 to pass). Scores range from 100 to 200 on the 2014 version). A score of 165 on each test is the benchmark for college and career readiness, and you will receive an Honors distinction if you reach this score. The four tests take seven and a half hours total and are administered by computer. You don't have to take them all on the same day, but some states enforce specific time frames for completing the tests. Most questions are multiple choice, although there is also a mix of fill-in-the-blank, drag and drop, and select-an-area questions, as well as an essay question on the Reasoning Through Language Arts section.

If you don't pass a test the first time around, you can retake it, although different states have different requirements for people who need to retake GED tests (such as additional fees or proof of attending a preparation class). Testing accommodations are available for those with disabilities; you can sign up for them through your online account after you register. You usually have to pay to sign up for the tests, but the cost varies from state to state. After you take each test, you will receive your scores within 24 hours. Here are some more details about the score report.

Which of the following can be used to measure temperature accurately
Illusion [34]

Answer:

Any of those terms can be converted to either of the other terms, so either term is correct. People are accustomed to everyday temperatures in Fahrenheit. The ideal gas law specifies that

P V = N R T     where T is in Kelvin which is Celsius + 273 deg.

List each layer of the earth, starting at the crust, and identify one characteristic of each layer.
Savatey [412]

Answer:

Hope it helps

Explanation:

The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases

The electric field strength between the plates of a simple air Capacitor is equal to the voltage across the plates divided by th
exis [7]

Answer:

d=\frac{112\,V}{1100\,\frac{V}{cm}} \\d=\frac{28}{75} \,cm=0.101818..  \,cm

Explanation:

Recall that the equation for the electric field intensity between the plates of a capacitor is given by:

E=\frac{\Delta V}{d}

where E is the electric field, \Delta V is the voltage across the plate of the capacitor, and "d" is the separation (distance) between the capacitor's plates.

So we need to solve for the distance in the equation above, but also make sure that the units for electric field and potential difference are in agreement. We then write the electric field strength in V/cm :

1.1kV/cm = 1100 V/cm

Now in the equation:

E=\frac{\Delta V}{d}\\1100\,\frac{V}{cm} =\frac{112\,V}{d\\}\\d=\frac{112\,V}{1100\,\frac{V}{cm}} \\d=\frac{112}{1100} \,cm\\d=\frac{28}{75} \,cm=0.101818..  \,cm

A child and sled with a combined mass of 48.8 kg slide down a frictionless hill that is 7.05 m high. If the sled starts from res
nexus9112 [7]

Answer:

Speed at bottom of the hill (v) = 11.74 m/s

Explanation:

Given:

Combined mass = 48.8 kg

Height h = 7.05 m

Find:

Speed at bottom of the hill (v)

Computation:

v² = 2gh

v = √2 x 9.8 x 7.05

v = √138.18

v = 11.74 m/s

Speed at bottom of the hill (v) = 11.74 m/s
