Answer: 692 J

Explanation:

La energía mecánica es la energía que se utiliza para realizar un trabajo determinado y se calcula con la suma de la energía cinética y la energía potencial de un objeto. En otras palabras, describe la energía de un objeto debido a su movimiento, posición, o ambos.

<u>La energía cinética es el trabajo necesario para acelerar un cuerpo desde el reposo hasta su velocidad final</u>. Entonces, es la energía que posee un cuerpo debido a su movimiento. Cuando gana energía durante la aceleración, el cuerpo mantiene la energía cinética a menos que su velocidad cambie, y el cuerpo realiza la misma cantidad de trabajo al desacelerar desde su velocidad actual hasta un estado de reposo. Por otro lado, <u>la energía potencial es la energía que posee un objeto debido a su posición con respecto a otros objetos.</u> Los tipos más comunes de energía potencial incluyen a la energía potencial gravitacional de un objeto que depende de su distancia al centro de masa de otro objeto (La Tierra), la energía potencial elástica de un muelle o resorte extendido y la energía potencial eléctrica de una carga en un campo eléctrico.

La unidad de energía en el Sistema Internacional de Unidades (SI) es el julio, que tiene el símbolo J.

La energía mecánica se calcula de la siguiente manera (tener en cuenta que la aceleración de la gravedad es un dato tabulado de 9,8m/s^2):

Energía mecánica = Energía cinética + Energía potencial

Energía mecánica = (1/2 * masa * velocidad^2) + (masa * gravedad * altura)

Energía mecánica = 300 J + (10kg * 9,8m/s^2 * 4m)

Energía mecánica  = 300 J + 392 J = 692 J

Why is it important for a cell to perform checks after DNA replication?
zimovet [89]

Answer:

A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.

Explanation:

Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.

It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.

Cigarette smoking and environmental chemicals

Tobacco smoke and certain environmental chemicals are known carcinogens (substances that can cause cancer in living tissue). The tobacco smoke from cigarette smoking contains harmful chemicals such as hydrogen cyanide, arsenic, ammonia, benzene, and many more. In fact, from 2009 to 2013, three out of 10 cancer deaths in the U.S have been attributed to cigarette smoking or exposure to tobacco smoke.
