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

Why does the weight of an object change when it is moved from the equator to the poles?
The weight of an object changes when it is moved from the equator to the poles due to the variation in gravitational force caused by the Earth's rotation. The force of gravity is slightly stronger at the poles compared to the equator, leading to a small change in weight.
Is walking on snow a physical or chemical change?
Walking on snow is a physical change because the snow remains as solid ice crystals and does not undergo any chemical reactions to form new substances.
Is walking an example of mechanical energy?
Yes, walking is an example of mechanical energy because it involves the movement and interaction of the body's muscles and bones in order to change the position of the body. This movement is powered by the conversion of stored chemical energy in the body into kinetic energy.
Does time go slower when you walk?
Time itself does not change, but walking can make it feel like time is passing more slowly due to increased focus on your surroundings and the physical activity engaging your mind. This perception can vary depending on your state of mind and the environment you are walking in.
What happens to the density of an object as you change its size?
As you change the size of an object, its density remains constant, assuming the mass stays the same. Density is a measure of how much mass is present in a given volume, so as the size changes, the mass and volume change proportionally, keeping the density the same.
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 along the same longitude line?
No, the time does not change as you move north or south along the same longitude line. Time zones are determined by lines of longitude, so as long as you stay on the same line, the time remains constant.
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.
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.
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.
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
What effects climate the most?
Climate is effected most by longitude. Longitude (up and down axis of earth) determines how far or close an area is the equator, measuring at 0 degrees Fahrenheit. The closer an area is to the equator the lower the temperature. The farther an area is from the equator, the higher the temperature.
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.
Does Earth's gravity change as you get closer to the equator?
no =)
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.
Does temperature change when changing the longitude?
Temperature does not typically change solely based on longitude. Temperature is primarily influenced by factors such as altitude, latitude, proximity to bodies of water or mountains, and prevailing wind patterns. While longitude can indirectly affect temperature through these factors, it is not a direct cause of temperature change.
