what is the instrument used by Christopher Columbus use to measure speed
anemometer
Heavy water accumulation on the street/road surface - and - the excessive speed of the vehicles travelling on that road.
Christopher Columbus's voyage across the Atlantic in 1492 covered approximately 2,400 nautical miles from Spain to the Bahamas. The journey took about 36 days, giving an average speed of roughly 2.2 knots (about 2.5 miles per hour). This speed varied throughout the voyage due to changes in wind and weather conditions.
If travelling at a speed of 50 km per hour, this is the same as about 31 miles per hour.
Columbus chose caravel ships for his fleet because they were highly maneuverable and suited for long voyages. Their shallow draft allowed them to navigate shallow coastal waters and rivers, making them versatile for exploration. Additionally, the combination of lateen sails provided better windward capability and speed, which was essential for the transatlantic journey he undertook. This design facilitated Columbus's goal of reaching Asia by sailing westward.

The instrument used for measuring the speed of winds is called an anemometer. It typically consists of cups that rotate in the wind, and the speed of rotation is used to calculate the wind speed.
This will depend upon the speed you are travelling at. If you are travelling at 60 miles per hour it will take you around 15 hours. Calculate this by dividing the distance (in miles) by the speed(in mph).
An instrument commonly used to measure speed is a radar gun, which uses radio waves to calculate the speed of an object in motion. Radar guns are often used by law enforcement to monitor vehicle speed on roads.
A lot of mathematical problems about travelling distances, assume that you are travelling at a constant speed.
Whatever speed the wind is travelling.
You can't calculate the wavelength from only that information. The speed, wavelength, and frequency of a wave are related. In order to calculate any of them, the other two must be known.
This is entirely dependent upon the speed you are travelling at. Speed = distance / time Rearranging, we find that time = distance / speed If you are travelling at 70 miles per hour for 15.1 miles then we can calculate the estimated time to be 15.1/75 which is equal to 0.201. This is how many hours it will take. We simply multiply by 60 to achieve the time in minutes which is 12.08
None or Infinity. What speed are you travelling? Are we walking or travelling the speed of light? Temporal distance is entirely dependant on velocities.
An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
