How much does one change longitude at the equator by walking due east one mile assuming the earth to be a sphere of radius 3956 miles?

Circumference = 2 pi R
Fraction of the circumference in 1 mile = [ 1 / (2 pi R) ]
Angle = (360 degrees) x fraction of the circumference
We know it'll be tiny, so let's right now change to seconds of longitude (3,600 seconds = 1 degree).
IF we accept the stated figure for the radius of the earth, then ...
Angle = (360 x 3600) / (2 pi R) = 1,296,000 / (7,912 pi) = 52.14 seconds of longitude

Is walking on snow a physical or chemical change?
The walking is not a change at all. The snow experiences a physical change (it gets compressed, and some crystals may melt due to the pressure).
Why does the weight of an object change when it is moved from the equator to the poles?
Because of centripetal acceleration you will weigh a tiny amount less at the equator than at the poles.
What are three ways that an object can change its velocity?
Walking skateboarding and riding your bile
Why does the temperature change from month to month?
because the angle of suns rays hitting the earth change. like the equator gets direct rays most of the year and that's why its the hottest
What is the product of pressure times volume?
A unit of energy such as Joules. Most often interpreted as Work assuming volume can change.
Does the time change as you go north or south of the Equator along the same longitude line?
No.
How does the linear distance separating each 1 degree of longitude change as you move from the equator toward the poles?
The linear distance across each degree of longitude at the equator is about 60 miles. That's as far apart as those lines of longitude get. As the lines of longitude run north (or south) to the north (south) pole, they converge until they all meet at the pole. That translates like this: the linear distance separating each degree of longitude is a maximum at the equator, and decreases to zero at the pole.
Does the time change as you go north or south of the equator?
In general, no, the time does not change as you cross the equator.
Did mass change when you move from equator to poles?
No. Your mass doesn't even change when you move from the equator to the moon.
What happens to a degree of longitude as you move from equator towards the poles?
Nothing. A change of 1 degree of latitude corresponds to a distance of about 69 miles, regardless of where on the earth you begin. The above answer is not exactly correct. Because the earth is ellipsoid rather than spherical (meaning it is slightly flattened at the poles), there is a slight difference in distance. It is closer to 68miles at the equator and 69miles at the poles. The flattened effect makes the distance increase slightly toward the poles.
Is it true that at the equator day length does not change?
yes. All the way around the equator the day length doesn't change.
what is 1 degree longitude difference equivalent to change in time?
0 degrees longitude
Does Earth's gravity change as you get closer to the equator?
no =)
Where on earth do the temperatures change very little from season to season?
Near the equator.Near the equator.Near the equator.Near the equator.
Is a degree of longitude longer at the eqautor or pole?
1 degree change of longitude corresponds to about 69 miles along the equator.All of the meridians of longitude converge at the north and south poles, so ateither of those locations, any change of longitude corresponds to zero distance.
Do the lengths of longitude lines change as you go west?
The lengths of longitude do not ever change, but on a map they appear to change only because the map is stretched at the center, expanding the distance between everything.
Where do you have the least temperature change between seasons?
At the equator.
