13.Calculate the number of joules of heat needed to change 50 grams of water by
50'C.

Answers

Answer 1

Answer:

16.7 kJ

Explanation:

mass of water = 50 grams

change in temperature of water = 50⁰c

specific heat of fusion of water = 334 J/g

calculate the amount of heat needed/required

= mass of water * specific heat of fusion of water

= 50 grams * 334 J / g

= 16700 J

note : we use the specific heat of fusion of water because the temperature change given and the change is below 100⁰c hence the water is still in liquid form

Answers

The correct answer is A) the Native Americans were forced to move west of the Mississippi River.

In the late 1700's many pioneers started moving into the Ohio Valley. The impact that this white movement had on the Native Americans that already lived in the Ohio Valley was that the Native Americans were forced to move west of the Mississippi River.

At the end of the 18th. century, white people started to move west and settled in the territories that formerly belonged to many Native American Indian tribes. Tribes in the Ohio River Valley were displaced due to the establishing of white Americans that had a different culture and tradition. These Native American Indians were displaced to other land and had to move further west to keep their own rituals, customs, and traditions.

Redacta un articulo de opinion con enfasis partucular en estos 3 puntos 1 la forma en que los pobladores del titicaca se han relacionado con su naturaleza para lograr sostenibilidad. 2 como se relaciona la poblacion en tu region con su naturaleza. 3 el abora una propuesta para lograr desarrollo sostenible utilizando los recursos de tu region.

Answers

La respuesta correcta a esta pregunta abierta es la siguiente.

La forma en que los pobladores del Titicaca se han relacionado con su naturaleza para lograr sostenibilidad es que han actuado de manera muy responsable para combinar las actividades agropecuarias, con la pesca, y han agregado el desarrollo turístico del área para generar mayores ingresos. La parte de sustantibilidad radica en que los pobladores del lago Titicaca cultivan de manera responsable, sin hacerle daño a la tierra y cuidan el lago para las aguas no se contaminen. Lo mismo le piden a los turistas. Que visiten pero sean muy cuidadosos con la naturaleza y el manejo de la basura.

Sucede algo parecido con la población en mi región y la relación con la naturaleza. Yo vivo muy cerca de dos volcanes y uno está activo en este momento. Es una zona turística por excelencia que recibe a muchos visitantes en su reserva ecológica y a muchos escaladores y montañistas que suben al otro volcán que no está activo. A todos se les pide que sean cuidadosos y no hagan fogatas para evitar incendios y que recojan su basura para no contaminar las áreas naturales.

Una propuesta interesante para lograr desarrollo sostenible utilizando los recursos de tu región es que el gobierno municipal pueda apoyar a la gente de esta localidad para que puedan instalar hostales, restaurantes, mercados, centros de descanso y enfermerías para atender mejor a los visitantes. De esta manera se fomentaría el consumo local ayudando a los pobladores de la región y se incrementarían los turistas porque saben que el área ya tendría más y mejores servicios.

What reasons does this article suggest are the causes of the movement away from family farms to larger farms?

Answers

Answer: Interest

Explanation:

One of the major reasons why there is movement from the family farms to personal farms is due to interest. Due to the situation of farming on the family farm, it restricts individuals from growing in the business but when they move out to their respective farm, they have room to improve, grow and want to consider large scale or commercial farming.

The article suggests that the movement is caused away from family farms to large farms is due to their vested interest. The family farms follow large farming due to their potent to extend at such extent.

The movement that trends from the family farms to large farms is due to the availability and the scope of expansion for family farms along with an intention to grow at a larger level.

The family farms are generally huge in size and they have the capacity to practice different types of farming growing different crops and make them available in the market.

The production of the crops and the farm products is in large numbers which results in expansion of the farms to increase the commercialization at such farms.

Due to availability of place in the family farms and capacities of production in the farms the interest of family farms is more vested towards moving towards larger farms.

Hence, the correct statement will be that the movement of family farms to larger farms is due to the vested interest in commercialization of farm's  produce and earn profits.

Explain why the motivational songs of the Nahham have come to symbolize emirati culture?

Answers

Answer:

Explanation:

assma Al Jandaly describes the traditional folk songs and dances of the region whose appeal has endured over time

Folk songs and dances of a region provide a key insight into the history and culture of the land and its people. Music and song have been an integral part of society for a long time. Musicians have imitated the sounds and rhythmic movements of birds and animals to express their feelings, thus developed their musical talents.

Folk songs and ballads are the early forms of music and have been passed down the generations, even before the advent of writing. These ancient art forms are particular to a nation and symbolise the richness of its culture. Folk songs continue to be popular.

The people of the UAE are known by their frankness and honesty and their emotional disposition to appreciate beauty. They have always been committed to preserving the poetic tradition inherited from their ancestors.

"Poets enjoyed a dominant position in society and their works were appreciated. Poetry knew no barriers and Rulers, scholars, merchants and common men exhibited their poetical talent in public," said Bilal Al Budoor, general secretary of the Cultural Scientific Association in the UAE.

Al Budoor explained that Al Nabati is a form of narrative epic poetry based on the life of popular Arab heroes. It has been very popular from ancient times as it was recited in colloquial Arabic.

"The Arabian gulf is blessed with shallow waters and timeless deserts. The coast of the United Arab Emirates extends 600 km along the Arabian gulf. The eternal deserts, adorned with beautiful windswept sand-dunes and verdant oases, lie further inland.

"The exposure to foreign lands and culture through trade relations, has enriched the music and songs of the Emirates. However, the core of their own folklore is intact."

He noted that the early notes of Arabian music were derived from the songs of the ancient camel herdsmen. The members of the ancient caravans sought refuge in beautiful verses, to break the silence and monotony of the raging deserts. The most popular of these songs is the Rakdh Al Rikab which means running of the camels. These songs still exist in the deserts of the Emirates.

The simple lifestyle and rich cultural heritage of the Bedouins have enriched the folklore of the desert. With the passage of time, the songs have attained the rhythm of waves and the glory of sand dunes.
