How many revolutions will a turntable that rotates through an angle of 3 over 2 pi in one second make in 60 seconds?
I guess you mean 3 pi over 2, ie 3π/2 though it may have been given to you as (3/2)π
To solve this, find the total angle turned in 60 seconds and divide by the angle in a whole turn, ie one revolution.
In 60 seconds it will turn through an angle of 60 × 3π/2 radians = 90π radians
One revolution is 2π radians
→ 90π radians = 90π/2π revolutions = 45 revolutions
(45 rpm - the figure calculated - was the standard for a single).
What else can I help you with?
Suppose that a disk rotates through five revolutions in 4 seconds. What is its displacements in radians in this time?
To find the displacement in radians, you can use the fact that one complete revolution corresponds to (2\pi) radians. If the disk rotates through five revolutions, the total displacement is (5 \times 2\pi = 10\pi) radians. Therefore, the displacement of the disk in 4 seconds is (10\pi) radians.
What is a step angle?
The nominal angle through which the step motor shaft rotates between adjacent step positions.
What is the angular velocity of the wheel before braking began if the wheel rotates through 6 radians in 2 seconds as it is uniformly brought to rest?
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
What is a axis?
AxisIn terms of astronomy, it is the imaginary line running through a planet around which it rotates. See the Related Link for a demonstration and further information.
How many seconds have you lived if you are 16 year old?
A minimum of 504,576,000 seconds but it depends on the time of day you were born and how many leap years you have lived through.

Which microwave oven has the most even cooking surface?
Microwave ovens which feature a glass turntable provide the most even cooking of foods. The turntable automatically rotates the food through the cooking zone to even out those hot and cold spots.
What advantages does a portable turntable have over a conventional one?
The main advantage of a portable turntable is that they take up less space than a conventional turntable. They are also easier to find through major retailers. A portable turntable is also small enough to be mobile.
A bicycle wheel rotates uniformly through 2 revolutions in 4 seconds What is the average angular speed of the wheel?
The average angular speed is the total angular displacement divided by the total time. Since the wheel completes 2 revolutions (2 x 2π) in 4 seconds, the total angular displacement is 4π. Thus, the average angular speed is 4π/4 = π radians per second.
What is the period of the suns revolutions?
It takes the Sun 250 million years to make a full revolution through the Milky Way's galactic core. It rotates completely once every 31 days at the poles, and once every 27 days at the equator.
Where can someone purchase a direct drive turntable?
One can purchase a direct drive turntable at a local retailer that offers such products. Turntables can also be purchased online through the web sites such as Amazon and eBay.
Can I buy a turntable that has USB?
Yes, the TEAC LP-U200 Turntable USB Recorder and CD/Radio has USB functionality. It can record directly through USB for excellent sound quality and ease of use.
Through how many degrees does the hour hand move?
Each hour, it rotates through 30 degrees, every twelve hours, it rotates 360 degrees.
When does the earth rotates through 360 degrees longitude?
The Earth rotates through 360 degrees of longitude every 24 hours. This rotation causes the cycle of day and night as different parts of the Earth are exposed to the Sun's light.
How did political revolutions of the 19th century how advanced the rights of Women?
Women began to demand the same rights men had and secured through political revolutions (APEX)
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!
How did Egypt become Egypt?
Modern Egypt did not become a country through war, but more through a series of revolutions
