Answer:

1.  Decreases,

2.   Increases,

3.   Increases

Explanation:

The heat which is a product of sun's energy, is transferred from the sun to the earth through radiation, conduction or convention. This heat passes through the earth atmosphere, then warms it , before becoming heat energy.

Therefore, Heat is transferred from the sun to the earth via electromagnetic waves . Because of this transfer, the entropy of the sun DECREASES, the entropy of the earth INCREASES and the entropy of the sun-earth system INCREASES.

A sound source emits 20.0 W of acoustical power spread equally in all directions. The threshold of hearing is 1.0 × 10-12 W/m2.
ahrayia [7]

Answer:

0.0018 W/m²

Explanation:

Power and intensity are related as:

I=\frac{P}{4\pi r^2}

P=  20.0 W (given)

r = 30.0 m (given)

I=\frac{20.0}{4\pi(30.0)^2}=0.0018 W/m^2

Intensity in decibels:

I(dB)=10log\frac{I}{I_o}\\=10log\frac{0.0018}{10^{-12}}=92.5 dB

What are plane mirrors ?
forsale [732]

Explanation:

Mirrors consist of reflecting surfaces that reflect light.

Reflection is a phenomenon of light wave (but also of other types of waves) in which a ray of light hits a surface, and then it bounces back into the original medium at a certain angle.

The direction of the reflected ray is determined by the law of reflection:

  • The incident ray, the reflected ray and the normal to the surface all lie in the same plane
  • The angle of reflection is equal to the angle of incidence (where both angles are measured between the ray and the normal to the surface)

A plane mirror is a type of mirror consisting of a straight surface. As a result, light incident perpendicular to the surface is reflected back exactly in the opposite direction.

The image formed by a plane mirror is:

- The same size as the object

- Virtual (it is located behind the mirror)

- Laterally inverted

- Upright
