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

b. density
c. pressure
d. temperature
Answer:
c. pressure
d. temperature
Explanation:
The Earth's layers all have different composition, and they all differ in the sense of being solid, or more liquid. There are two main factors that contribute to this, the pressure and the temperature. Both of these factors are able to change the condition of a material individually, but when they are combined than they have even greater influence. The crust is solid, and the main reason for that is that the pressure and temperature are relatively low. The mantle is consisted of molten rock because the temperature and pressure are higher. The outer core is liquid, as it has much higher pressure and temperatures even than the mantle. The inner core is the layer with the highest pressure and temperature, and they are so high that the material is actually solid because of it.
