How far will the Moon travel across the sky in 1 hour?
1/24th of the radius of the earth Ignoring the small effect of the orbital motion of the moon itself, and considering only the effect of the earth's daily rotation of 360 degrees in 24 hours, the moon apparently does about 360 degrees/24hours, or 15 degrees per hour. The moon's angular diameter is close to half a degree so the distance travelled in 1 hour is about 30 times its diameter. The moon in its orbit goes around the earth in about 30 days, that's about 1/2 degree per hour, about 1 diameter, so about 29 times its diameter per hour across the sky is probably closer.
How pi is derive?
Pi, of course, is the ratio of a circle's circumference to its diameter. This number is just slightly over three, and is irrational (it never repeats or terminates).There are various formulas for deriving pi. You can even obtain an excellent approximation by dropping a pin on a floor of evenly spaced parallel lines. See the associated link for some of the formulas. Note: Machin's formula (using inverse tangents of unit fractions) is calculated in radians. In this respect it is, in effect, a definition of pi in terms of itself. Nevertheless it is a most curious relationship.π/4 = 4tan-1(1/5) - tan-1(1/239)More curious yet is the incredible relationship between pi and the natural log e:eπi = -1, where i is the imaginary square root of -1. i2 = -1.
My dad is 5'11 and my mom is 5'6 how tall will you be?
Potential height depend on your genetics. The half and half to make a whole set genes you receive from your parents. Basing on how tall your father and mother are will not give you the precise answer that will result later. You may gather an idea on how you will be by looking at them. Factors such as nutrition and physical activity will effect your development. One way to can increase your height as you are growing is by frequently playing basketball. It has been proven that if you are physical active in playing basketball and eat well, having a balance meal, as you grow from childhood to adulthood, ages 10 to 18, you will stretch well.
