travel exactly east or west
Surface waves (as the name suggests) travel along Earth's surface. Seismic waves that travel through earth's interior are known instead as body waves.
These are known as seismic waves.
One degree of latitude, and one degree of longitude along the equator only, is equivalent to roughly 69.1 miles (111 km). One degree of latitude, and of longitude on the equator only, is also equal to about 60 nautical miles.
Latitude and longitude are angles. So any unit of angle will work.Examples include radians, grads, degrees, etc.Mostly on account of seafaring tradition and the history of navigation, thesecoordinates are still almost always listed and stated in degrees (and fractionsof degrees, like decimals, or minutes and seconds).
The lines of longitude are vertical; longitude measures the horizontal distance from 0 degrees longitude. Here is a mnemonic that helps me: Latitude sounds a little like 'ladder-tude', and the rungs of a ladder are horizontal. I picture myself 'stepping up or down' the lines of ladder-tude, and this moves me farther north or farther south. That leaves vertical for longitude. While the lines of longitude are drawn from north to south, their locations measure a parameter that changes from east to west; longitude tells you how far east or west you are (in degrees, not distance) from the prime meridian (zero degrees longitude). Lines of latitude are drawn from east to west, and they measure how far north or south you are. So running the risk of confusing you, the "concept" of longitude (what is your position east/west of the prime meridian) is really horizontal in nature. This can be a little hard to grasp. Draw a line on a piece of paper; make the line exactly one inch from the left margin. You have drawn the line 'up and down', but the line is there to tell you how to get one inch from the margin (left-right) no matter where you are on the paper. And no matter where you are on the line, you are one inch to the right of the left margin. So if you travel up and down a line of longitude, you might cover several thousand miles, but you haven't budged from your measure of longitude-- how far you are (in degrees) from the prime meridian. As you travel along your line of longitude, you see hash-marks with changing numbers of degrees. These are not changes in longitude, but in latitude. They answer: How far north or south am I, along this line of longitude? When doing navigation, the simple thing is that lines of longitude are all long. Since they all go through both the North and South Pole, they are all the same length. Latitude lines vary in length. Latitude: LAT=FLAT Longitude: LONG (heights)
If you travel along a line of longitude from the South Pole, you would travel directly northwards.
A negative acceleration, or deceleration, is the cause of unbalanced forces, where the force opposing the direction of travel is greater than the force along the direction of travel.
Based on Newton's first Law of Motion, any (net, if two or more forces are at work) force acting on a moving object, and that, when resolved, having a component orthogonal to the direction of travel, will change the direction of the object. Simplistically, that is any force that acts on the object at an angle to the direction of motion. Resolution of a vector (of which force is a member) involves breaking down the vector along the three orthogonal axes (x, y, and z in the Cartesian system). For the sake of convenience, one of three axes should be along the direction of travel. =================================
Longitudinal waves are waves that have the same direction of vibration along their direction of travel, which means that the vibration of the medium (particle) is in the same direction or opposite direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves
That rate of change, along with the direction in which it's changing, comprise the object's acceleration.
Coriolis effect
No , sound waves are longitudinal waves ,their vibrations are along the direction of travel of wave.
No, it is not possible. For a stationary wave, two identical waves should travel in opposite direction along a string.
Longitudinal waves are waves that have the same direction of oscillations or vibrations along or parallel to their direction of travel, which means that the oscillations of the medium (particle) is in the same direction or opposite direction as the motion of the wave.
The only ways you can travel along the equator is by going due west or due east and you can do it indefinately. Any other direction you would not be travelling along the equator
A Compressional wave.
The gradient of a function, in a given direction, is the change in the value of the function per unit change in the given direction. It is, thus, the rate of change of the function, with respect to the direction. It is generally found by calculating the derivative of the function along the required direction. For a straight line, it is simply the slope. That is the "Rise" divided by the "Run".
