Which statement best describes how an electromagnetic motor works?

Chemistry
1 answer:
inn [45]3 years ago
5 0

Answer:

Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.

Explanation:

Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.

What rules should you follow when adding and subtracting? Check all that apply. 1. The exponents in scientific notation should b
Damm [24]
The answer to this question would be: 
<span>2. The exponents need to be the same so the leading numbers can be added or subtracted.
3. The result has the same number of decimal places as the least precise number.

</span>The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5
The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.

A gas has a pressure of 0.470 atm at 60.0 C. What is the pressure at standard temperature?
OLEGan [10]

Answer:

P2=0.385atm

Explanation:

step one:

Given that the temperature T1=  60 Celcius

we can convert this to kelvin by adding 273k to 60 Celcius

we have T1= 333k

pressure P1= 0.470 atm

step two:

we know that the standard temperature is T2= 273K

Applying the temperature and pressure relationship we have

P1/T1=P2/T2

substituting our given data we have

0.47/333=P2/273

cross multiply we have

P2= (0.47*273)/333

P2= 128.31/333

P2=0.385 atm
