Geography
1 answer:
garik1379 [7]3 years ago
3 0

Answer:

33300J

Explanation:

Given parameters:

Mass of ice  = 100g = 0.1kg

Initial Temperature of water  = 0°C

Final temperature  = 0°C

Unknown:

Amount of energy = ?

Solution:

The amount of energy is given by;

  Amount of energy =  mL

m is the mass

L is the latent heat of fusion  = 3.33 x 10⁵ J/kg

   Amount of energy = 0.1kg x 3.33 x 10⁵J/kg

  Amount of energy  = 33300J

Calculate and compare the albedo temperature of Mars to Venus. Then compare the two albedo temperatures the planet’s albedo temp
Kryger [21]

Answer:

The albedo temperature for Mars and Venus are 210K and 184 K respectively.Mars albedo temperature is closer to its black body temperature such that the Venus has more albedo.Thus there is a chance that Mars would have had life in their history.

Explanation:

The albedo temperature is given as

Te =\left [\dfrac{L(1-a)}{ (16\pi \sigma D^2}\right]^{1/4}

Here

L = Solar luminosity = 3.846*1026 W m-2 K-4

D = distance from Sun

σ = the Stefan-Boltzman constant = 5.6704 * 10-8 W

a is the albedo constant whose value for Mars is  0.250 while for  Venus it is 0.900

So the albedo temperature is given as

Venus: 184 K

Mars: 210 K

The black body temperature is given as

Te =\left [\dfrac{L}{ (16\pi \sigma D^2}\right]^{1/4}

By substitution of the values, the black body temperature for Venus and Mars are as

Venus: 327 K

Mars: 225 K

Mars albedo temperature is closer to its black body temperature such that the Venus has more albedo.

Thus there is a chance that Mars would have had life in their history.

How would you describe the delegates to the philadelphia convention
marusya05 [52]

<u>Answer:</u>

The Philadelphia convention was attended by all white men. Most delegates to the convention were young men aged between 20 and 30. Some re-owned political figures also attended the convention. The delegates who attended the convention were from mixed backgrounds.

About half the delegates were college graduates and men aged more than 30 were investment bankers or had an interest in the stock market. The delegates were wealthy and educated and so it is believed that the convention did not include the entire American society.

The eastern part of the border between the united states and mexico is delineated by.
NISA [10]

Your answer is, The Rio Grande

<h3><u>What is The Rio Grande?</u></h3>

The Rio Grande, known in Mexico as the Río Bravo del Norte and as the Río Bravo, is one of the principal rivers in the southwestern United States and in northern Mexico. The length of the Rio Grande is 1,896 miles and originates in south-central Colorado, in the United States, and flows to the Gulf of Mexico.

<h3><u>How does The Rio Grande affect the environment?</u></h3>

A finite amount of water flows through the Rio Grande every year, so when there are shortages, every city along the river is affected. Due to climate change, hotter and drier seasons are reducing the snowpack that melts to feed the Rio Grande, and rising temperatures are increasing evaporation from the reservoirs.

Thus, <u>The Rio Grande</u> is your answer.

imagine that you were a doctor who is studying the spread of a disease in your country how could you use new technologies to geo
Svetach [21]

Answer: GIS technology and collection of health data.

Explanation:

If a doctor is studying the effects of the diseases in the country he can make use of the geographic data to study the occurrence of the diseases in the past and with the help of the geographic data could analyze it through the use of the Geographic Information System technology that helps to study the areas on the world map that shows similar patterns of infections.

So the use of the technology can help in understanding problems of the disease which are generally related to the most and humid tropics as compared to the cold polar climate that has a different type of diseases and flues etc.

Also the collection of real-time data on the patients the doctor can match the symptoms and help in studying the further root cause of the problems.
