The MA of a lever is 4. If you have to lift the object up 20 cm,
how far will you have to pull down?

Answers

Answer 1

Answer:

jayfeather friend me

Explanation:

Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.

Answer:

Hi There!

Explanation:

1 to 8 km/sec

S-waves are transverse waves. Even though they are slower than P-waves, the S-waves move quickly. Typical S-wave propagation speeds are on the order of 1 to 8 km/sec. The lower value corresponds to the wave speed in loose, unconsolidated sediment, the higher value is near the base of Earth's mantle.

What are unnatural pollutants?

It is the resulting pollution from human activity. It covers the use of fossil fuels in manufacturing, transportation, and thermoelectric power plants, as well as industrial gas emissions, mining, processing, and stone crushing.

The physical degradation or contamination of the environment caused by the release of hazardous, dangerous, or toxic chemical substances is known as pollution.

Oxides of nitrogen (NOX) and volatile organic compounds (VOC), commonly referred to as hydrocarbons, undergo chemical interactions that result in ozone. Both close to the earth and high in the atmosphere, this reaction is possible.

Therefore, the correct option is a. ozone.

The RARA gene on chromosome 17 provides instructions for making a transcription factor called the retinoic acid receptor alpha (RARα). A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity (transcription) of particular genes.

Explanation:

Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.

What is the process that the tree uses to get its energy called?Does this process directly or indirectly affect the energy needs of animals such as the ostrich?

Answers

Photosynthesis is the process by which trees and all other flora (plants) get energy. And I think that it directly helps animals, such as ostriches, by providing food and O2 (oxygen). Without oxygen, humans and animals couldn't survive because there is too much CO2 (carbon dioxide) in the air (humans get this thing called carbon dioxide poisoning, which can kill you eventually). Also, without food, we would all starve to death.

Hope this helps! :)

Plants use a process called photosynthesis to transform solar energy into their own energy.

What is photosynthesis?

Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.

Solar or radiant energy is converted into chemical energy during photosynthesis. The rate of photosynthesis has a direct impact on the productivity of agricultural crops.

It gives the atmosphere the oxygen that all living things need. It keeps the ecosystem's oxygen and carbon dioxide levels in check.

The process by which leaves take in carbon dioxide and water and use the power of the sun to transform them into chemical compounds like sugars that feed the tree is known as photosynthesis.

Thus, through the process of photosynthesis, tree uses to get its energy.

Read the excerpt from Seaplanes by Roberto BarerraFlying boats have a fuselage, or body, that looks and acts like a ships hull. This hull enables them to float on the water very easily. Two small floats underneath its wings keep the flying boat stable in rough water. These seaplanes are usually larger and more stable on water than floatplanes are. A floatplane is a seaplane that has two long floats, called pontoons, under the fuselage. This is the only part of the plane that touches the water. Unlike flying boats, floatplanes often come in a wide variety of sizes. An amphibious vehicle can be either a flying boat or a floatplane with wheels. This allows the aircraft to land on both land and water.Which BEST describes the purpose of the paragraph?A.to explain how seaplanes are usedB.to encourage people to use seaplanesC.to list all of the types of seaplanesD.to describe the different parts of seaplanes what is the work done when a 400.n force is use to lift a 400.n object 3.5 meters strait up what is the molar mass of Br2 in grams Find the value of x.ABCD EFGH During operations outside declared hostilities, you may delay contact with local authorities.
