What makes up 70% of the earth's total volume, as is relates to the earth's structure?

1 answer:

3 0

The appropriate response is the mantle. The thick center layer in the strong piece of Earth. This makes up 70% of the Earth's aggregate volume. It is a layer inside an earthly planet and some other rough planetary bodies. For a mantle to shape, the planetary body must be sufficiently huge to have experienced the procedure of planetary separation by thickness.

Light travels at 3. 0 × 108 m/s in a vacuum and slows to 2. 0 × 108 m/s in glass. What is the index of refraction of glass?.

Sergio039 [100]

The required value of the index of refraction of glass is 1.5.

Given data:

The speed of light in a vacuum is, $c = 3.0 \times 10^{8} \;\rm m/s$ .

The speed of light in a glass is, $v = 2.0 \times 10^{8} \;\rm m/s$ .

Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,

n = c / v

Solving as

$n = \dfrac{3.0 \times 10^{8}}{2.0 \times 10^{8}}\\\\n = 1.5$

Thus, we can conclude that the required value of the index of refraction of glass is 1.5.

Alex

If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 180 m away

The muzzle velocity of the bullet is 275 m/s

Answer:

y = -1.1109 m

Explanation:

Range = $\frac{v^2sin2\theta}{g}$
