Because you did not use the voltage switch in Europe you damaged the voltage regulator in the hair straightener. Unlike CD players, and other small electronics (which will not turn on if the adaptor or DC input is incorrect) direct to plug appliances will turn on and over-load or short out. Because your straightener only reaches 86 degrees it is safe to say you over loaded it with 220volts (or more). Because all United States plugs are no higher than 120volts you damaged it by overloading it with at least 100 extra volts.
Bottom line, buy a new one, you won't be able to get this one fixed.
Yes rather easily actually with a hair straightener turned up to approximately 200 degrees celsius
Generally, hair straighteners and curlers that are more expensive are designed to reach temperatures that curl/straighten more effectively, without doing a large amount of damage to your hair. For example, a straightener such as a ghd which only reaches 178 degrees is more effective and less damaging than a Remington straightener that reaches 200+ degrees.

i believe you'd be traveling northwest.
"30 degrees east / 20 degrees north" is the description of a point in northern Sudan about 700 miles south of Cairo. There's no obvious reason why your location should have an influence on my destination. And if you are in northern Sudan, or for that matter anywhere else on Earth at 20 degrees latitude, then I promise you that I am not traveling to join you if I can avoid it.
You would be traveling North.The exact direction is 2 degrees East of true North.
when the temperature of the air is 25 degrees Celsius, the velocity of a sound wave traveling through the air is approx.
This only true when north or south from the equator. Lines of latitude are parallel lines around the earth starting at 0 degrees from the equator. From the equator to the poles has an angular measurement of 90 degrees. The poles are 90 degrees north and south of the equator respectively. If you travel north 90 degrees for instance, which is one quarter of the globe, you would be at the North Pole. You cannot then travel any further north. Any further travel would be south. If you then travel another 10 degrees you would be reducing your northing by ten degrees. 10 degrees from 90 degrees is 80 degrees. Hence you would be at the latitude of 80 degrees north. A bit like walking up a hill that is 90 feet high. Once you get to the top 90 feet up, you cannot get any higher. If you walk further you are going downhill.
The ship is traveling west which means that the ship is traveling at a bearing of 270 degrees. The lighthouse is 10km northwest of the ship at time point 0. Northwest means the lighthouse is at a bearing of 315 degrees from the ship. This means that the angle between the direction the ship is going and the lighthouse is 315 - 270 = 45 degrees.
189 degrees
You are flying west (start at north, and work your way around clockwise, 90 degrees for every quarter of a circle)
Depends on wether one counts clockwise or counter-clockwise. Assuming starting at the south point and traveling 112.5 degrees from there one ends up at west-north-west. Going counter-clockwise and traveling "backwards" one ends up at east-north-east.
