what is the apparent angle the diameterof the moon subtends as seen from the earth in radians. average moon earth distance3.84*10e8
radius of the moon 1.74*10e6
That is easy: 2*radiusMoon/distancefromEarth
In " who knows if the moon's," what is the moon seen as?
To find the apparent angle that the diameter of the Moon subtends as seen from Earth in radians, we can use the formula:
Angle = (Size of the object) / (Distance from the object)
In this case, the size of the Moon is given as its diameter, which is 2 times its radius (2 * 1.74 * 10^6). The distance from the Moon to Earth is given as 3.84 * 10^8.
Using the formula, we can calculate the angle:
Angle = (2 * 1.74 * 10^6) / (3.84 * 10^8)
Simplifying the expression:
Angle = 3.48 * 10^6 / 3.84 * 10^8
Angle = 0.0090625 radians (rounded to 5 decimal places)
So, the apparent angle that the diameter of the Moon subtends as seen from Earth is approximately 0.00906 radians.
