How do you convert kN/m2 to kg/m2?

Convert from kilonewtons to newtons by multiplying by 1000 Given a starting unit in kN, or kilonewtons, multiply by 1000 to get the corresponding number of newtons. One newton is a kilogram meter per second squared, and a kilonewton is 1000 kilogram meters per second squared.Divide the result by 9.8 meters per second squaredAccording to Newton's second law, F=ma, which is to say that force is the product of mass and acceleration. This can be algebraically rearranged to m = F/a, or mass equals force divided by acceleration. The precise acceleration due to gravity varies with latitude, alti..

What is a good cell analogy example to use in class?

The cell is protected by its outer boundary, the plasma membrane. Like a gated community, the cell has security guards that control what molecules are allowed to enter and leave the cell.\nThe ribosomes are the small factories of the cell. They float throughout the cytoplasm and create proteins. The endoplasmic reticulum is the big factory complex, and it too manufactures proteins. Some of these proteins are kept within the cell and turned into ATP by the mitochondria, the cell's power plants. Others are transported to the golgi apparatus.\nThe golgi apparatus is the packaging plant. It s..

What is the biggest asteroid?

Ceres was the first asteroid ever discovered and is sometimes referred to as a dwarf planet. It is distinguished by a rocky core and an icy surface. In January 2014 scientists discovered vapor emissions from Ceres using data from the Herschel Space Observatory. As of 2014 no visit has been made to Ceres, but the spacecraft Dawn is scheduled to explore the asteroid by early 2015.

What is the function of the cerebellar vermis?

The cerebellum is located in the rear portion of the shallow, depressed area of the skull. It is divided into two hemispheres that are connected by a thin, elongated structure known as the vermis. The cerebellar hemispheres are partitioned into three lobes: flocculonodular, posterior and anterior. The cerebellum contains four types of deep nuclei from where all cerebellar projections come from. These include the interposed nuclei, dentate nucleus, vestibular nuclei and fastigial nucleus.There are three primary functional cerebellar subdivisions: vestibulocerebellum, cerebrocerebellum and the s..

What is the main function of the pyrenoid?

Pyrenoids are sub-cellular, proteinaceous micro-compartments that exist within the chloroplast of many algae. They consist of 90 percent RuBisCo (Ribulose-1,5-biphosphate-carboxylase-oxygenase), an enzyme that plays a key role in photosynthesis. Pyrenoids have a plastic structure that allows them to migrate and respond to light within the chloroplast.Pyrenoids were first discovered in 1803, but scientists did not know a lot about them until the 1970s, when they were successfully isolated from algae. Scientific evidence suggests that pyrenoids are capable of converting dissolved inorganic carbo..

What is the chemical formula of zinc acetate?

Another name for this compound is zinc diacetate, the reason for which is observed when looking at its structure, which is comprised of one zinc ion and two acetate groups. Zinc acetate exists in two crystalline forms, known as the alpha (wurtzite) and the beta (sphalerite). Its color ranges from white to grayish white, or it can appear as a yellowish powder.

What is the subunit of enzymes?

Enzymes participate in numerous metabolic and biological reactions within the human body. They catalyze reactions, or speed up the rate at which they occur, without changing the reactants or the products of the overall reaction. The majority of enzymes can catalyze reactions on their own, but some need additional help. The compounds that help these enzymes catalyze reactions are known as co-factors and are typically inorganic ions or metallo-organic molecules.

What is a Mendelian trait?

Mendelian inheritance, which is also referred to as Mendelian genetics or Mendelism, is a description of science that explains how characteristics that are hereditary are handed down from parents to their offspring. Mendel felt that there were two types of traits, recessive and dominant, which were controlled by a single gene. Some examples of these traits include a cleft chin, dimples, freckles or whether an earlobe is attached or not.

How much is 10 milliliters?

A milliliter is a measuring unit used in countries that employ both the Imperial and International systems. Used to measure volume, the milliliter is equal to 1 cubic centimeter, which allows for an easy conversion to the International system. It is commonly used in medicine and cooking. An important use for the milliliter in medicine involves dosing procedures.
