No, because the magnitude of the velocity is always greater than speed.
Answer:
<em>The centripetal acceleration will be increased to 1.33 of its initial state. </em>
Explanation:
<h3>Centripetal acceleration</h3>
The Centripetal acceleration of an object is the acceleration of the object along a circular path moving towards the center of the circular path. The centripetal acceleration is represented in the equation bellow
...................................... 1
where 
is the centripetal acceleration
v is the tangential velocity
and r is the radius.
<h3>How the Change of Radius Affects the Centripetal Acceleration</h3>
Reference to equation 1 the centripetal acceleration ( ) is inversely proportional (
) to the radius of the circle or path. this means that when the radius increases the centripetal acceleration reduces and when the radius reduces the centripetal acceleration increases. The radius was reduced to 0.75R in the question that will amount to 1.33 increase in the centripetal acceleration. This can be obtained by multiplying the centripetal acceleration by the inverse of 0.75 which is 1.33.
Therefore, when the radius is reduced by 0.75R , the centripetal acceleration of the steel ball will increase by 1.33. since the period is kept constant

The Sun shines by turning hydrogen into helium in its core, this process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a lot of energy is created.
