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.
If travelling at a speed of 50 km per hour, this is the same as about 31 miles per hour.
At the time that Columbus was making his trip across the Atlantic, very few Portuguese sailors were using celestial navigation and Columbus was not really one of them . Celestial navigation is a technique that measured angles between objects in the sky and the horizon to locate a ship's position on a globe. Instead, Columbus preferred a technique known as dead reckoning . A ship's navigator determines the position of his ship by tracking the distance and direction traveled from a known, fixed point. This technique depended on a navigator being able to accurately gauge the ship's speed and direction; the direction was tracked using a compass and speed was determined using a complicated system of markers. There's some controversy surrounding Columbus' league measurement . A league is made up of four miles, but many countries had a different measurement for how long a mile was. Looking at Columbus' records, the typical "Roman" mile of 4,860 feet is not accurate. Most historians believe he used the Geometric League as a measurement for his travels, where a mile would equal 4,060 feet. Columbus' crew had a bad reputation but it was actually composed of experienced sailors, none of whom were convicts. His most famous ships remain the Pinta, the Nina, and the Santa Maria , the three ships he took on his first voyage . His other ships included the San Juan and the Captiana. There is also a bit of controversy surrounding Columbus' first landing place because he visited five islands before landing on the actual continent of South America. Columbus' original account of his journey disappeared after he gave it to the Queen of Spain. However, on the island of San Salvador, South America, a whitewashed cross has been erected on the beach at Landfall Parks that is widely accepted as his first landing place.
Columbus was an Italian-born Spanish explorer. He operated under the Spanish Flag in all four of his major voyages to the New World. He did not sail under the French Banner, you must be thinking of LaSalle, or Champlain (of Lake Fame) or other French Voyagers such as Cartier who discovered Canada- no he did not get sponsorship from the as-yet unfounded Fifth avenue Jeweler!

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.
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.
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
