What is the formula for the angular velocity?
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
What is a use of trigonometry to find the heights of buildings and trees?
Trigonometry is the study of angles ond lengths. If you know one angle and one side length of a right traingle, you can find all the other values. If you know your distance from a tall object, and the angle made by the base of the tall object, your feet, and the top of the object, you can find the height of the object.
What is the angular velocity in radians per second of the second hand of a clock?
The angular velocity of the second hand of a clock is pi/30 radians per second.
Angular displacement symbol which represents it?
theta or θ
What is the angular velocity of a 50kHz sine wave?
Letω = angular speed (we can't do velocity with the given information),f = frequencyω = 2π fω = 2π (50 * 1000 Hz) = 100,000π rad/sec ~= 314,159 rad/spec
What is the angular size of a circular object with 1 inch diameter viewed from 4 yards?
To find the angular size, we need to convert the distance to the object into radians. 4 yards is approximately 12 feet or 144 inches. The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
What is the small-angle formula?
The small angle formula is used for measuring the distance to a far away object when the actual size and angular size are known, or for finding out the actual size of a faraway object when the distance to the object and angular size are known. In arc-seconds: a = 206265 x D/d where a = the angular size of the object in arc-seconds D = the actual linear size of an object in km d = the distance to the object in km 206265 = the number of arc-seconds in a complete circle divided by 2pi In Radians: a = D/d where a = angular size of object in radians
How do you find out the direction of angular accelaration?
The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant
When the angular speed of an object increase its angular momentum may or may not increase?
if the angular speed of an object increase its angular momentum will also increase
Why pulling your arms in causes you to go faster?
When you are spinning there is a force called angular momentum that keeps you spinning and the angular momentum forms a ratio with the size of the object that is spinning so as you bring your arms inward, your size decreases increasing your angular momentum which spins you faster.
What is the angular size of circular object with a 2 inch diameter viewed from a distance of 4 yards?
It is 0.8 degrees.
What is the angular size of a circular object with a inch diameter viewed from a distance of 2 yards?
It is approx 0.8 degrees.
What is the angular size of a circular object with a 2 inch diameter viewed from a distance of 4 yards.?
It is 0.8 degrees.
If a net torque is applied to an object that object will experience which of the following a constant angular speed angular acceleration or an increasing moment of inertia?
angular acceleration
What happens to the angular velocity of an object as it starts to decrease in size?
Because momentum is conserved, if the size or mass decreases, its inertia decreases so its angular velocity will increase
What is the magnification power and resolving power?
Magnification is the size of the image of an object as compared to the true size of the object.Resolving power is the ability of an imaging device to separate (i.e., to see as distinct) points of an object that are located at a small angular distance.
The product of an object's rotational inertia and its rotational velocity is?
The object's angular momentum
