A planet has an orbital period of 3.24 years. What is the average distance of the planet from the sun?
Brut [27]

Answer;

-5.83 AU

Explanation;

A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun.

Using the equation;

t² = a³

t = 3.24 years, the time it takes the planet to orbit .

a (astronomical units) = 3.24 ^3/2

                                    = 5.83 anatomical units (AU).

An individual running a marathon may experience periods of oxygen deprivation that can lead to
Harman [31]

Answer:

A. anaerobic respiration in muscle cells, forming lactic acid

Explanation:

Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.

The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
