Answer:
1) Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force.
2) The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.
3) There are the two components of the projectile's motion - horizontal and vertical motion.
4) The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

how will solar energy affect us in the future? ESSAY DUE AT 9:00 A.M tomorrow. Please finish I will give 100 points
Answer:
i love you:)
Explanation:
Solar energy has come a long way in a decade. Back in 2010, the global market was small and highly dependent on subsidy regimes in countries such as Germany and Italy. This year there will be more than 115 gigawatts (GW) of solar installed across the world, which is more than all other generation technologies put together. It is also increasingly low cost, especially in sunnier regions where it has already become the lowest-cost form of new electricity generation.
In the coming years, technology improvements will ensure that solar becomes even cheaper. It could well be that by 2030, solar will have become the most important source of energy for electricity production in a large part of the world. This will also have a positive impact on the environment and climate change.
Going forward the solar industry has very clear cost-reduction roadmaps, which should see solar costs halving by 2030. There is already a move in place towards higher-efficiency modules, which can generate 1.5 times more power than existing, similarly sized modules today using a technology called tandem silicon cells. These are going to have a large impact going forward.
In addition, there are production innovations coming down the pipeline that will reduce the amounts of costly materials such as silver and silicon used in the manufacture of solar cells, as well as innovations such as bifacial modules which allow panels to capture solar energy from both sides. The other important innovation is around how best to integrate solar into our homes, businesses and power systems. This means better power electronics and a greater use of low-cost digital technologies.
What this means is that solar will reach, in many parts of the world, a levelized cost of energy that will make it unbeatable compared to fossil fuels. Given that solar is so easy and quick to install, not to mention flexible - after all, solar can be used to power something as small as a watch or as large as a city - it should mean that solar installations continue to grow over the coming decade. This could also be very good for the climate. Now that is something bright to write about.

Which of these statements accurately describes the energy conversion that occurs in cellular respiration?
A) ATP is converted into thermal energy.
B) Chemical energy is converted into ATP.
C) Heat energy is converted into chemical energy.
D) Light energy is converted into kinetic energy into the products.
Chemical energy is converted into ATP in cellular respiration. Therefore, option B is correct.
What is cellular respiration?The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, like oxygen, to generate significant amounts of energy that are used to power the major creation of ATP.
Both the cytosol and mitochondria of cells participate in cellular respiration. While pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation take place in the mitochondrion, glycolysis happens in the cytosol.
The primary goal of cellular respiration is the production of energy, even though it can also result in the production of other substances like lactic acid or carbon dioxide. Every biological process requires energy. Therefore, option B is correct.

< saved?
ab Room
Answer:
Conditions are more marine higher in
the intertidal and more terrestrial
lower in the zone.
Explanation:
This is because the intertidal zone in the Marine sea shore is submerged or overwhelmed with water during high tide and exposed to the air during low tide. The zone is in different forms which might be from sandy beaches to rocky cliffs. intertidal zone change frequently once or twice every day since it is constantly affected by crashing waves. They have moist temperature,humid air and also high degree of salinity.

B. Compounds can be broken down by physical changes, but elements cannot.
C.
Elements are made of identical atoms, whereas compounds are made of
identical molecules,
D. A compound contains many different kinds of elements, whereas an element
contains many different kinds of atoms.
Answer:
C. Elements are made of identical atoms, whereas compounds are made of identical molecules.
Explanation:
Elements are made of identical atoms, whereas compounds are made of identical molecules because elements are made of atoms of only one kind while on the other hand, compounds are the pure substance that is made of molecules that is similar as well as different from one another. Both element and compound are pure substance. Compound can be broken down by chemical means whereas elements can not be broken down.

How did this giant sequoia tree obtain obtain enough matter to become one of the largest organisms on earth?
Answer: The question is incomplete because Options are not given and here are the options gotten from another website.
A.The giant sequoia tree absorbs water through its roots to make its own matter.
B. The giant sequoia tree takes up carbon dioxide from the surroundings to make its own matter.
C. The giant sequoia tree transforms the matter in sugar and oxygen through photosynthesis to make its own matter.
D.The giant sequoia tree transforms the matter in water and carbon dioxide through photosynthesis to make its own matter.
The correct option is D.
D.The giant sequoia tree transforms the matter in water and carbon dioxide through photosynthesis to make its own matter.
Explanation:
This is because they get water and mineral nutrients like nitrogen e.t.c from the soil and CO2 from the atmosphere and use these to build their bodies through the process of photosynthesis. Many other plants also it more faster but sequoias engage in it for a very long time and, as they grow larger and larger, they photosynthesis more and more and that way they produce larger bodies.

Plants that reproduce sexually generate seeds. These seeds are often dispersed away from the parent, either through wind , animals , or water. Look at the seed shown in this image of bullrush plants. What form of dispersal do you think it uses, and why ?
Can anyone help me in this question
Help!!!
Answer:
wind/water either one.
Explanation:
It can reproduce from rhizomes or seed and uses the wind and water to disperse its seeds.
Based on the appearance of the seed shown in the image of bullrush plants, it appears that these seeds are dispersed by wind.
What are different form of seed dispersal?Seed dispersal is the movement of seeds away from the parent plant, allowing them to establish in new locations and increase the chances of survival and reproduction. There are several forms of seed dispersal, including:
Wind dispersal: Seeds with feathery structures or plumes, such as dandelions, are carried by the wind.Animal dispersal: Animals can carry seeds away from the parent plant in their fur or digestive systems, such as berries eaten by birds.Explosive dispersal: Some seeds are expelled from their pods with great force, such as in the case of squirting cucumbers.Water dispersal: Seeds with waterproof coats can float on water and be carried long distances, as seen in coconut palms.Biotic dispersal: Seeds can also be dispersed by other living organisms, such as ants that carry seeds to their nests and bury them there.Learn more about seed dispersal, here:
