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.

vampirchik [111]

Answer:

These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward

During a plane showcase, a pilot makes circular "looping" with a speed equal to the sound speed (340 m/s). However, the pilot ca
Dmitriy789 [7]

Answer:

1472.98 m

Explanation:

Data provided:

Speed of circular looping, v = 340 m/s

Acceleration, a = 8g

here,

g is the acceleration due to the gravity = 9.81 m/s²

Now,

the centripetal acceleration is given as,

a=\frac{v^2}{r}

r is the radius of the loop

on substituting the respective values, we get

8\times9.81=\frac{340^2}{r}

or

r = 1472.98 m

A circular coil of wire having a diameter of 20.0 cm and 3000 turns is placed in the earth's magnetic field with the normal of t
Bess [88]

Explanation :

It is given that,

Diameter of the coil, d = 20 cm = 0.2 m

Radius of the coil, r = 0.1 m

Number of turns, N = 3000

Induced EMF, \epsilon=1.5\ V

Magnitude of Earth's field, B=10^{-4}\ T

We need to find the angular frequency with which it is rotated. The induced emf due to rotation is given by :

\epsilon=NBA\omega

\omega=\dfrac{\epsilon}{NBA}

\omega=\dfrac{1.5}{3000\times 10^{-4}\times \pi (0.1)^2}

\omega=159.15\ rad/s

So, the angular frequency with which the loop is rotated is 159.15 rad/s. Hence, this is the required solution.
