180° E or 180° W are used interchangeably, so it is 180°
Saying something boils at 65 degrees means that that is the minimum temperature required to vaporize it. So anything under 65 degrees and it will return to a liquid. So about 64 degrees or so.
Those are the Earth's magnetic field lines, which extend from the North Pole to the South Pole and form a protective shield around the planet. They help protect the Earth from solar wind and cosmic radiation.
Halley'scomet. It will return in 2061
If you want to be as accurate as possible you will need to start with the temperature of the air. Once you know the temperature of the air you plug it in to this formula: V = 331 √1 + (T/273) V is the velocity of sound in air at temperature T in degrees Celsius. Now that you know how fast sound will travel through the air at the current temperature, measure the time it takes for the sound to be transmitted and the echo received. Take that number and plug it in to this formula: V = m/s or Velocity = meters/seconds From that we get: Distance = Velocity/time Divide the distance in half and you have your distance from the object which the echo bounced off of.

Displacement is only the distance from the starting point. As long as you return to where you started, then you can travel 1.0 x 10^999999999999 miles and still have a displacement of zero.
Marco Polo first traveled eastward from Venice to Cathay (what is now China). Many years later, he traveled westward from Cathay to return home.
