Alecsey [184]4 years ago
4 0

Answer:

over harvesting, pollution, introduction of invasive species such as new predators and food competitors

Explanation:

The main cause of mass extinction is Humans cause extinction of a species through overharvesting. The second main  cause is pollution ., introduction of invasive species such as new predators and food competitors, habitat destruction, overhunting and other influences. Another very important cause of mass extinction is the unsustainable human population growth.

The five mass extinction events are

Ordovician Mass Extinction

Devonian Mass Extinction

 Permian Mass Extinction

Triassic -Jurassic Mass Extinction

and Cretaceous -Tertiary (or the K-T) Mass Extinction.

Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft.
Three types of spacesuits exist for different purposes: IVA (intravehicular activity), EVA (extravehicular activity), and IEVA (intra/extravehicular activity). IVA suits are meant to be worn inside a pressurized spacecraft, and are therefore lighter and more comfortable. IEVA suits are meant for use inside and outside the spacecraft, such as the Gemini G4C suit. They include more protection from the harsh conditions of space, such as protection from micrometeorites and extreme temperature change. EVA suits, such as the EMU, are used outside spacecraft, for either planetary exploration or spacewalks. They must protect the wearer against all conditions of space, as well as provide mobility and functionality.

A relief plane flying horizontally at 65.0 m/s is delivering a
SVETLANKA909090 [29]

The height of the plane delivering a food package to people stranded on an island is 722.2 m.

<h3>Time of motion of the food package</h3>

The time taken for the food package to hit the ground level is calculated as follows;

X = vt

where;

  • X is horizontal distance traveled by the food package
  • v is horizontal distance
  • t is time of motion

t = X/v

t = 789/65

t = 12.14 seconds

<h3>Height of the plane</h3>

h = ¹/₂gt²

where;

  • h is height of fall of the food package which is height of the plane
  • t is time of motion of food package
  • g is acceleration due to gravity

h = (0.5)(9.8)(12.14²)

h = 722.2 m

Thus, the height of the plane delivering a food package to people stranded on an island is 722.2 m.
