Answer:
The correct answer is - the article does not provide a scientific basis for the information
Explanation:
Generally, Magazines publish articles with reliable information and sources that are universally accepted or have a scientific basis behind the information. It is already known that wastewater is recycled and purified before making it available for drinking.
In this article, there is no scientific basis behind the information as no scientific data mentioned or ignore test and practice in use from the years which is scientifically tested.
The correct answer is C. The birthrate is higher than the death rate.
Explanation
The graph is about the growth of the world population, this shows the population growth of the world, Asia, Africa, Europe, United States, Canada and Greenland, Mexico, Central America, Caribbean Islands, and South America, and Oceania (Australia and nearby islands in the Pacific). This graph covers the time from 1950 to 2050 divided into decades. In the specific case of Africa in 1950 it had a population of close to 300 million people. Subsequently, in 2010 the population of Africa was close to 1 billion people and the projection for the year 2050 is 2 billion people. According to this, it can be concluded that the birth rate is higher than the death rate because the population has a growth trend, which indicates that more people are born than die.
Answer:
A) Falso, cuando un resorte se estira, este comienza a acumular energía potencial. Al soltar el resorte, este tratara de volver a su forma natural, consumiendo la energía potencial y transformándola en energía cinética.
B) Falso. Potencia esta definido como la cantidad de trabajo efectuado por unidad de tiempo, a mayor potencia, mas rápido se completa un trabajo.
C) Verdadero, el trabajo es escalar, pues resulta de un producto punto entre dos vectores, la fuerza y el desplazamiento.
D) Falso, el cambio en la energía cinética de un cuerpo es igual al trabajo neto aplicado sobre ese cuerpo. Es decir, si le aplico trabajo a un cuerpo, estoy cambiando su energía cinética.
E) Falso, la fuerza del vagón sobre los pasajeros NO es constate, ya que esta fuerza esta relacionada con la velocidad a la que se mueve el vagón, y sabemos que la velocidad del vagón va cambiado durante el trayecto (podemos experimentar esta fuerza al pasar de una horizontal a una pendiente muy pronunciada, ya que hay un gran cambio de velocidad, y si hay cambio de velocidad, hay aceleración, y por la tercera ley de Newton, si hay aceleración, hay fuerza), pero si es verdad que esta fuerza es un factor importante al diseñar una montaña rusa.
Answer:
This statement is true
Explanation:
Technologies associated with agriculture systems have greatly enhanced crop yields around the world. An example of this is the "Green revolution" in 1950-1960, where the combination of genetic improvement methodologies with the use of fertilizers was critical for the amazing increase in crop yields, particularly in new varieties of rice and wheat. Indeed, the agronomist who developed some of these high yielding varieties of wheat, Norman Borlaug, was awarded the Nobel Peace Prize for his contribution to the extensive increase in crop production, thereby helping to alleviate world hunger.
