Question
e. As the radius of the circle is doubled, the acceleration is __________________ (one-fourth, one-half, two times, four times) the original value.
Solution
The question seems to be referring to the concept of centripetal acceleration in physics, which is given by the formula a = v^2 / r, where 'a' is the acceleration, 'v' is the velocity, and 'r' is the radius of the circle.
If the radius 'r' of the circle is doubled, then according to the formula, the acceleration 'a' would be halved.
So, as the radius of the circle is doubled, the acceleration is one-half the original value.
