Answer:
t = 0.22 s
Explanation:
The rate of curvature can be defined as the ratio of the radius of curvature to the time taken to bend the wire to that radius of curvature. Therefore,
v = r/t
where,
v = rate of curvature
r = radius of wire
t = time taken
Here, in our case:
v = 9 units/s
r = 2 units
t = ?
Therefore,
9 units/s = 2 units/t
t = (2 units)/(9 units/s)
t = 0.22 s
Therefore, it takes 0.22 second to bend a straight wire into a circle of radius 2 units
