A que altura debe moverse un costal de cemento de 50kg para asegurar que su energía potencial sea de 10,500 j?

Answers

Answer 1

Answer:

21 m

Explanation:

La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.

La energía potencial se da como;

E = mgh

Dónde;

m = masa del cuerpo

g = aceleración por gravedad

h = altura del cuerpo

Aquí necesitamos obtener la altura del cuerpo.

h = E / mg

h = 10500/50 * 10

h = 21 m

1) Read the following paragraph and answer the following questions.
The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO​2​ and water. Like oil spills cause damage

to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.

In your own words, describe how the time required for digestion can be used to determine the time of death.

Answers

Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.

Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.

Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.

However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.

C. unnecessary or nonfunctional organs in modern species
D. fossils of the same species found diverse geographic locations

Answers

The answe is D because location has nothing to do with genetics

The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

What do you mean by Evolution?

Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.

Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.

Therefore, the statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

Compared to freshwater fishes, marine fishes: drink seawater and produce a large volume of urine. do not drink seawater in an effort to conserve as much water as possible. produce a large volume of dilute urine in an effort to rid their bodies of excess water. tend to gain water by osmosis since their internal salt concentration is higher than that of seawater. tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.

Answers

Answer:

The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.

Explanation:

In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.

In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.
