A space probe lands on a planet with 1/2 the gravitational force as the earth. What happens

1 answer:

7 0

Planet with 1/2 the gravitational force as the earth. the effect of the mass and weight of the space probe is described below.

Explanation:

At an altitude of 2642 km (approx. 1641 miles) above the Earth's surface, the gravitational acceleration will be 4.89m/s^2, which is half of 9.78 m/s^2 (the gravity at the surface).
When the distance between the 2 objects is halved, the gravitational force between the 2 objects is doubled. when the distance between the 2 objects is doubled then the gravitational force doubles.
Yes, a space probe that weighs 1000 pounds (excluding fuel) sitting in its launch vehicle on the launch pad will weigh much more from launch until the rocket's engines shut off. At that point it will become weightless. It becomes weightless because it's in free fall, even though it is still heading away from the Earth.
In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. ... However, if we went from Earth to Mars, our weight would change because Mars has less gravity than Earth. Gravity is a force pulling matter together.

elixir [45]

Answer:

(Bone deposition),

(Bone resorption),

Remodeling

Periosteal ,

Nedosteal,

The compact bone,

Spongy bone.

Explanation:

The constant, dynamic process of continual addition of new bone tissue (bone deposition) and removal of old bone tissue (bone resorption) is a process called bone remodeling. This ongoing process occurs at both the periosteal (outer) and nedosteal (inner) surfaces of a bone.

It is estimated that about nedosteal of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example, the compact bone in our skeleton is replaced at a slower rate than the spongy bone.

Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is ___

alekssr [168]

Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is Invasive Species.

The process by which a natural ecosystem can no longer support its native species is known as habitat destruction. Reduced biodiversity and species abundance result from the displacement or death of the creatures that once occupied the area. The loss of biodiversity is mostly caused by habitat degradation.

An imported organism that overpopulates and damages its new habitat is referred to as an invasive species. Even though the majority of imported species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.

The most frequent methods for invasive plants, animals, microorganisms, and other species to spread to new ecosystems are thought to be human activities like those involved in international trade and the pet trade.

Lerok [7]

B) Photosynthesis The Sun is the ultimate source of all energy in the universe. Plants being the main primary producers or autotrophs, use solar energy to make their own food through photosynthesis, thus converting energy into the organic matter that can be consumed by all organisms. They form the basis of almost all food chains from where consumers derive their food.

stepan [7]

Answer:

There are innermost serious membranes that cover the heart is Parietal Pericardium.

Explanation:

Heart is covered by pericardium in two sides, inner and outer sides. The inner membrane is parietal pericardium and the outer one is visceral pericardium. Pericardium is made up of fiber tissues that strongly protect the heart from all around.

The main function of pericardium is to protect the heart from any injuries and prevent the infections. The serious pericardium helps in lubricating the heart.
