<u>Answer</u>:

Orbit's semi-major axis length and  its period  is directly proportional.

<u>Explanation</u>:

Orbital period(T) is the time taken for an celestial object to make one complete revolution in the orbit around other object

According to  Kepler's laws  3rd of planetary motion  stating

The square of an orbital period T of a planet is “directly proportional” to the cube of the "semi-major axis"  of its orbit.

The orbital period  T is given by

T=2 \pi \sqrt{\frac{a^{3}}{\mu}}

Where

a is the semi-major axis of the orbit

µ = GM  which is the standard gravitational parameter

With G is the gravitational constant  and M is the mass of  body.

Sauron [17]

Answer:

<em>likely to decrease downstream in arid regions and increase downstream in temperate regions</em>

<em></em>

Explanation:

Arid regions are is a region with a severe lack of water, usually to the extent that affect the organisms living in the region. Arid regions are characterized by a very low depth of rainfall per year. Temperate region on the other hand experience more distinct seasonal change and wider temperature change. Temperate regions get a fairly large amount of rainfall per year.

In arid regions, the soil is very dry, and the rate of infiltration and percolation is high relative to the amount of rainfall available. The effect is that more water is infiltrated into the soil as you move downstream, leading to a decrease in the discharge of a stream as you move downstream. Most temperate region have soils that are usually saturated in the peak of the rainfall season, leading to a greater stream discharge as you move downstream.

A sound wave traveling at 340 m/s is generated by a 480 Hz tuning fork.
Shtirlitz [24]

Answer:

Wavelength = 0.7083 meters

Explanation:

Given the following data;

Speed of wave = 340 m/s

Frequency = 480 Hz

To find how long is the sound wave, we would determine its wavelength;

Mathematically, the wavelength of a waveform is given by the formula;

Wavelength = velocity/frequency

Wavelength = 340/480

Wavelength = 0.7083 meters
