Which of the following is a characteristic shared by both Brazil and Mexico?a. A prime minister is the head of government.
b. Corruption and high crime rates are a serious challenge.
c. There is no freedom of religion or freedom of speech.
d. Citizens first get the right to vote at age 21.

Answers

Answer 1

Answer: In Mexico, the head of the government is the President - so a) is false.

Also, in both countries there is freedom of religion (they might be Christian majority countries but they're secular) and freedom of Speech

The correct answer is that they both struggle with b. Corruption and high crime rates -for example in Mexico this is caused by the War on Drugs.

Answer 2

Answer:

The correct answer is - b. Corruption and high crime rates are a serious challenge.

Both Brazil and Mexico are countries that have huge problems with the corruption and the high crime rates.

The corruption seems to be an integral part of their respective societies and it can literary be found everywhere and about everything, from the most ordinary things on the streets, to the highest circles of the government and the institutions.

The high crime rates are also kind of a trademark for both of these countries. The cartels have huge power and influence in these countries, and it seems that doesn't matter how much the government tries to destroy them it doesn't really have any effect. In Mexico, the situation is so bad that there are multiple areas that are totally controlled by the cartels, where they have their own rules and the government doesn't have any authority at all.

Answer:

The orbital angular momentum of the Earth is equal to the product of the mass of the Earth (6.0x 10^24 kg) and its orbital velocity (29.7 km/s) multiplied by its distance from the Sun (1.5x 10^8 km), which results in a magnitude of 3.6x 10^40 kg m^2/s.

The spinning angular momentum of the Earth is equal to the product of its mass (6.0x 10^24 kg) and its angular velocity (7.3x 10^-5 radians/s) multiplied by the square of its radius (6.4x 10^6 m), which results in a magnitude of 3.8x 10^37 kg m^2/s.

Final answer:

a) The magnitude of Earth's orbital angular momentum with respect to the Sun is [ Select ] kg m^2/s. b) The magnitude of its spinning angular momentum is [Select ] kg m^2/s.

Explanation:

To calculate the magnitude of Earth's orbital angular momentum with respect to the Sun, we need to use the formula:

Angular Momentum = Moment of Inertia * Angular Velocity

For Earth's orbital angular momentum, the moment of inertia can be calculated using the formula for a sphere:

Moment of Inertia = (2/5) * mass * radius^2

Substituting the given values:

Moment of Inertia = (2/5) * 6.0 x 10^24 kg * (6.4 x 10^6 m)^2

Next, we need to calculate the angular velocity. The time taken for Earth to complete one revolution around the Sun is known as the orbital period. The orbital period of Earth is approximately 365.25 days or 31,557,600 seconds.

Angular Velocity = 2π / Orbital Period

Substituting the values:

Angular Velocity = 2π / 31,557,600 s

Now, we can calculate the orbital angular momentum:

Orbital Angular Momentum = Moment of Inertia * Angular Velocity

For the spinning angular momentum, we can use the same formula:

Spinning Angular Momentum = Moment of Inertia * Angular Velocity

However, the moment of inertia for spinning angular momentum is different. It depends on the mass distribution of Earth and its axis of rotation. Since Earth is considered a sphere, the moment of inertia for spinning angular momentum can be calculated using the formula mentioned earlier.

Substituting the given values:

Moment of Inertia = (2/5) * 6.0 x 10^24 kg * (6.4 x 10^6 m)^2

Finally, we can calculate the spinning angular momentum:

Spinning Angular Momentum = Moment of Inertia * Angular Velocity

What causes a 'V' shaped valley? Option 1: Glacial erosion Option 2: River erosion Option 3: Wind erosion Option 4: Mass wasting

Answers

The correct answer to the question "What causes a 'V' shaped valley?" is Option 2: River erosion.

A 'V' shaped valley is formed by the erosive action of a river or stream over time. As the river flows, it erodes the surrounding rocks and sediments, gradually deepening and widening its channel. The erosive forces of the water, combined with the movement of sediment and debris carried by the river, carve out a distinct 'V' shape.

The process of river erosion involves the wearing away of the riverbed and banks through several mechanisms. Firstly, hydraulic action occurs when the force of the moving water dislodges and carries away loose particles of rock and soil. Secondly, abrasion or corrasion happens as the river's load of sediments scours and rubs against the riverbed, further deepening and widening the channel. Finally, corrosion or solution occurs when the river's water chemically dissolves certain types of rocks, such as limestone.

Over time, these erosive processes shape the landscape, creating a 'V' shaped valley with steep sides and a narrow bottom. The steep sides of the valley are known as valley walls or valley slopes, while the narrow bottom is called the valley floor or channel.

It is important to note that while glacial erosion can also create U-shaped valleys, wind erosion and mass wasting (such as landslides or rockfalls) are not typically responsible for the formation of 'V' shaped valleys.
