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.
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.
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

The factor most responsible for the increase in Japan's dependency ratio is the "Increase in life expectancy."
This is because, with the increase in life expectancy, Japan has a high number of older adults. These older adults often pay little or no taxes.
A high dependency ratio is a depending ratio that is greater than 62.5
In Japan, the dependency ratio is 69.1, and the reason can be traced to the increased life expectancy of its population.
Hence, in this case, it is concluded that the correct answer is Increase in life expectancy.

b. The IMF and the World Bank are considered special agencies of the UN.
c. The IMF and the World Bank focus their efforts on promoting world trade.
d. The Bretton Woods Conference is the commonly used name for the conference that created the IMF and the World Bank.
The correct answer is C on E2020
The equator is similar to the prime meridian in a way that both the prime meridian and equator are imaginary base lines from which locations of earth can be measured. The correct option is B.
The equator is a hypothetical line hypothetically drawn on the globe that divides it into the northern and southern hemispheres and marks the latitude 0° parallel. It is situated equidistant from the poles.
Prime meridian in a geographic reference system, a prime meridian is any line of longitude when longitude is defined to be 0°.
The Northern and Southern Hemispheres are divided by the Equator. At 0° latitude, the Equator is located. The Prime Meridian travels through Greenwich, England, at latitude 0°.
Thus, the correct option is B.
