The characteristics of the shadow allow to find the result for the change of the sun's rays are:
-
As the person advances from the equator to the poles the rays are less perpendicular, which is reflected in a longer shadow.
The shade is a space where the sun's rays do not reach.
When the person is at the equator, his shadow is very small, indicating that the rays are falling vertically.
As the person increases his latitude, a shadow begins to appear every larger shade, due to two processes:
-
The earth is spherical, therefore there is an angle between the normal to the earth's surface and the sun's ray , which is why there is a region where the sun does not reach.
- The Earth has an inclination with respect to the sun and this inclination changes in the course of the year.
When the person is just over the north pole, the shadow should be infinite, which indicates that the person is parallel to the sun's rays. In reality, due to the inclination of the earth, the shadow is very long, but finite.
In conclusion using the characteristics of the shadow we can find the result for the change of the sun's rays are:
-
As the person advances the sun's rays are less perpendicular, which is reflected in a longer shadow.

Answer:
Explanation:
Given that,
Initial angular velocity,
Acceleration of the wheel,
Rotation,
Let t is the time. Using second equation of kinematics can be calculated using time.
Let is the final angular velocity and a is the radial component of acceleration.
Radial component of acceleration,
So, the required acceleration on the edge of the wheel is .
Answer:
(a). The magnitude of the uniform magnetic field is 10.02 μT
(b). The the magnitude of the total magnetic field is 10.78 μT.
Explanation:
Given that,
Number of turns = 210
Radius = 5 cm
Current = 38 mA
Current in the wire = 500 mA
We need to calculate the magnetic field inside a coil
Using formula of magnetic field
Put the value into the formula
Now a straight wire is inserted into the coil that carries 500 mA. It travels down the central axis of the coil
Distance
We need to calculate the magnetic field from the straight wire
Using formula of magnetic field
Put the value into the formula
This field is perpendicular to the wire.
The magnitude of magnetic field is
Hence, (a). The magnitude of the uniform magnetic field is 10.02 μT
(b). The the magnitude of the total magnetic field is 10.78 μT.
