As you know, plants are usually green<span>, which means that most other colors are absorbed. One of the most common pigments is called chlorophyll, and one of the varieties is responsible for the </span>green<span> color of plants; it strongly absorbs </span>blue<span> and </span>red<span>light, which leaves only the </span>green<span> light to make it to our eyes.</span>
Yes , increased tension suggests increased molecular attraction between the molecules of the ropes which affect the increase in the speed of wave.
The answer is Air Resistance
<span>Reducing the distance between them. In theory, also increasing the mass; but you can't really change the mass of an object. However, you can compare the forces if you replace an object by a different object, which has a different mass.

Answer:
v = 112.424 km / s
Explanation:
Given:
d = 3.84 x 10 ⁸ m , R = 63 x 10³ m , m earth = 5.97 x 10²⁴ kg , G = 6.67 x 10⁻¹¹ N * m² / kg² , v₁ = 14.8 x 10 ³ m / s
Using the equation
KE + PE = initial KE + PE
¹/₂ * m * v₂² - G * m/ R = ¹/₂ * m * v₁² - G * m/(R+d)
v₂² = v₁² + 2*G * m [ 1/R - 1/(R+d) ]
v₂² = 14.8 x 10 ³ m /s + 2 * 6.67 x 10⁻¹¹ N * m² / kg² * 5.97 x 10²⁴ kg [ 1 / 63 x 10³m - 1 / ( 63 x 10³ + 3.84 x 10⁸ m ) ]
v = √ 1.26 x 10¹⁰ m² / s²
v = 112.424 x 10³ m/s
v = 112.424 km / s
