If the it took the object travelling at 25m/s 1 second to travel a quarter of the circle, it means a quarter of the circle is 25m (it travels 25m in one second).
If the quarter of the circle is 25m than the circumference of the circle is 100m.
We want to calculate the radius of the circle.
Remember that the equation for finding the circumference contains the radius. We can use that equation to solve for the radius.
Circumference = 2πr
π = pi or 3.1415...... ( a number )
r = radius
Since we know the circumference, plug it in.
100m = 2πr
solve for the radius by isolating r.
100m/2π = r
r = radius = 100m/2π = 50m/π = 50/π meters
<h2>
Answer: Radius = 50/π meters</h2>
Red Giants are the stars that currently in the late phase of the Stellar Revolution. One of the main features of a red giant is its variations on brightness.
Red Giants are formed because of the constant helium-burning process from the stars (which keep making it bigger and bigger) to the point where it almost ran out of it.
Answer:
Explanation:
Given
initial angular velocity is 
when motor is turned of it started decelerating with 
angular acceleration
angle turned before coming to halt
here final angular velocity is zero
No of revolutions will be
