Answer:
b) normal
Explanation:
The angle of refraction (transmission) Θt is the angle between the refracted ray and the normal N'. 2. When a light ray hits a surface normally, the angle between the incident ray and the normal is 0, so Θi = 0. Since the angle of reflection equals the angle of incidence, Θr= 0.
Answer:
Since their wings and body develop the drag. When there is warm air then they expand their wings. Since,soaring birds and glider pilots have no engine, they always maintain their high speed to lift their weight in air for hours without expending power by convection

To solve this problem it is necessary to apply the rules and concepts related to logarithmic operations.
From the definition of logarithm we know that,

In this way for the given example we have that a logarithm with base 10 expressed in the problem can be represented as,

We can express this also as,

By properties of the logarithms we know that the logarithm of a power of a number is equal to the product between the exponent of the power and the logarithm of the number.
So this can be expressed as

Since the definition of the base logarithm 10 of 10 is equal to 1 then

The value of the given logarithm is equal to 6
