Answer:

a. The Earth orbits the sun

Explanation:

Anchorage is the largest city in the United state of Alaska.

The major reason why we have seasons anywhere on the earth is the orbiting of the sun around the earth. Since the orbit of the earth is elliptical around the sun so it sometimes comes near the sun and sometimes far away from the sun due to which the average temperature of the earth keep varying during the entire year in phases of the distance from the sun.

When the earth is closer to the sun then the average temperature of the earth is relatively warmer than the average temperature when the earth is farther from the sun.

Tilt of the earth's axis also complements this phenomenon of season change but without the revolution of the earth around the sun in its elliptical orbit that could not be possible.

bixtya [17]

Answer:

a) The velocity of the car is 7.02 m/s and the car is approaching to the police car as the frequency of the police car is increasing.

b) The frequency is 1404.08 Hz

Explanation:

If the police car is a stationary source, the frequency is:

f_{a} =(\frac{v+v_{c} }{v} )f_{s} (eq. 1)

fs = frequency of police car = 1200 Hz

fa = frequency of moving car as listener

v = speed of sound of air

vc = speed of moving car

If the police car is a stationary observer, the frequency is:

f_{L} =f_{a} (\frac{v}{v-v_{c} } )=(\frac{v+v_{c} }{v-v_{c} } )f_{s} (eq. 2)

Now,

fL = frequecy police car receives

fs = frequency police car as observer

a) The velocity of car is from eq. 2:

1250=1200(\frac{v+v_{c} }{v-v_{c} } )\\1250(v-v_{c} )=1200(v+v_{c} )\\v_{c} =\frac{50*344}{2450} =7.02m/s

b) Substitute eq. 1 in eq. 2:

f_{L} =(\frac{v+v_{p} }{v-v_{c} } )(\frac{v+v_{c} }{v-v_{p} } )f_{s} =(\frac{344+20}{344-7.02} )(\frac{344+7.02}{344-20} )*1200=1404.08Hz

What is a homopolar motor?????)
PSYCHO15rus [73]

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.
