What is the average linear speed of a bicycle wheel with a radius of 10 inches which rotates 90 degrees in 2 seconds?

Curious to try this one: if it travels 90° in 2 seconds, then it travels 360° in 8 seconds, that would be ten inches in 8 seconds. So, in one minute, it would travel 75 inches; in one hour it would travel 4.500 inches, or 375 feet, or 0.071022 mph.

A bicycle wheel rotates uniformly through 2 revolutions in 4 seconds What is the average angular speed of the wheel?
Angular velocity (omega) = delta theta / delta time omega = 2 /4 = .5 rev/s = pi radians/s
What is the earths rotational period?
The earth rotates 360 degrees every 23 hours, 56 minutes and 4.100352 seconds.
The earth rotates 60degrees does in?
360 degrees is the intuitive answer, but it is not correct. The earth completes a 360 degree rotation in about 23 hours, 56 minutes and some odd seconds, which is the sidereal, or true, rotational period of the earth. I don't know the exact degrees in 24 hours, but it will be reasonably close to 361 degrees (roughly 1 extra degree per day to account for a full rotation over the course of a year).
How much time is required for a bicycle to travel a distance of 100M at an average speed of 2M S?
Approx. 50 seconds
What is the motion of Uranus?
It takes 84.02 Earth years (sidereal years) to orbit the sun. And the rotation of Uranus on its axis it takes 17 hours, 14 minutes, and 24 seconds.
How much time is required for a bicycle to travel 100 meters at an average distance of 2 meters per second?
approx. 50 seconds
When does the earth rotates through 360 degrees of longitude?
In almost exactly 24 hours.
What do minutes and seconds have to do with longitude and latitude?
Each degree is divided into 60 minutes, each of which is divided into 60 seconds - as for angles in a circle. This can cause confusion since the minutes and seconds do not correspond to their use in measuring time.The earth rotates through 360 degrees in 24 hours. This means that the earth rotates 1 degree = 60 minutes (angle) in 4 minutes (time).Hope I got that last bit right!
What are the symbols for degrees minutes and seconds?
Degrees: ° Minutes: ' Seconds: "
How many degrees do the stars move around Polaris at night?
The answer depends on how long the night is. With respect to distant stars the earth rotates once in every 23 hours 56 minutes and 4 seconds. Over that period, the stars will move through 360 degrees.
What is the unit rate for a fan that rotates 2000 times in 40 seconds?
50
How many degrees will earth now rotate in a solar day?
You are a clever questioner, indeed. You have asked a subtle and interesting question. You probably know that there are at least two distinct answers to the question, because there are two different kinds of day. The sidereal day is the period during which earth rotates 360 degrees relative to the distant stars (not the sun). If you were far above the solar system looking down on earth from the north, you would see that earth rotates a full 360 degrees relative to the stars, but still has to rotate a little more to reach the starting point relative to the sun, because we orbit the sun, this complicates things a little bit. So in a sidereal day, the earth rotates exactly 360 degrees, but this day lasts only 23 hours 56 minutes and 4.1 seconds, roughly. The synodic day is the period during which earth rotates one time relative to the sun. This rotation will be slightly more than 360 degrees, because as explained above the earth has to rotate a little extra (beyond a full 360 degrees) in order to reach the starting point relative to the sun. This is the day as we typically experience it. So if you are asking about the earth's rotation during a synodic day, the rotation is closer to an average of 360.9856 degrees per day. Another way to look at this is to consider the earth's coordinate system. There are 360 degrees of longitude. It is possible to consider the earth's degrees of longitude as the basis of your measurement, so that you can say the earth rotates 360 degrees of longitude relative to the sun on average each day, even though the absolute rotation of the earth is closer to 360.9856 degrees on average.
