Answer:

D. Asthenosphere

Explanation:

The asthenosphere is relatively plastic part of the mantle which underlies the brittle lithosphere. In the asthenosphere, it is generally believed that the rocks are in ductile state and easily moves. It is the site of convection within the earth. In mantle convection, hot and light materials rises and keeps moving into upper crustal levels till they solidify. Here also, cold and denser materials sinks deeper till they turn to melt. This differences in temperature and density sets up a convective cell within the mantle. Several convective cells are in the mantle.

g A beam of light incident on a smooth flat mirror at an angle of 25o relative to the surface normal of the mirror. What is the

WINSTONCH [101]

To solve this problem we will resort to the concept of angle of incidence and refraction.

Since it is a reflection on a mirror, the angle provided for refraction will be equal to that of the incidence, that is, 25 °

The angle of reflation is always perpendicular to the surface so it is necessary to find the angle with respect to it.

$\theta = 90-25$

$\theta = 65\°$

Therefore the angle of the reflected beam of light made with the surface normal is 65°

All music, _______ in the world, is from only ______ notes.

AnnZ [28]

Answer:

All music in the world, is form only two notes and those notes are described below in detailed explanation.

Explanation:

In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.

3. A boat at sea is being moved by the ocean current at 5 metres/minute directly to the east. At the same time it is being moved

faltersainse [42]

Explanation:

A boat at sea is being moved by the ocean current at 5 metres/minute directly to the east.

At the same time, it is being moved directly to the north at 3 metres/minute by a strong wind.

We need to find the magnitude and direction of the boat's overall velocity.

As both velocities are moving perpendicular to each other. The resultant velocity is given by :

$v=\sqrt{5^2+3^2} \\\\=\sqrt{25}\\\\=5\ \text{metres/minute}$

For direction,

$\tan\theta=\dfrac{v_y}{v_x}\\\\=\dfrac{3}5{}\\\\\theta=\tan^{-1}(\dfrac{3}5{})\\\\=30.96^{\circ}$

Hence, this is the required solutin.
