The nature of the image depends on the position of the object which is the candle in this case.
<h3>What is a concave mirror?</h3>
A concave mirror is one of the types o curved mirror. We must note that the position and nature of the image is determined by the position of the object as shown on the ray diagram.
In this case the ray diagram is missing hence the question is incomplete. The nature of the image depends on the position of the object which is the candle in this case.

Answer:
HUYGENS, CAN I S HAVE BRAINLIST?
Answer:
29.3 rad/s
Explanation:
Moment of inertia in straight position, I1 = I
He takes 2 rotations in 1.5 second
So, Time period, T = 1.5 / 2 = 0.75 second
w1 = 2 x 3.14 / T = 2 x 3.14 / 0.75 = 8.37 rad/s
Moment of inertia in tucked position, I2 = I / 3.5
Let the new angular speed is w2.
By the use of conservation of angular momentum, if no external torque is applied, then angular momentum is constant.
L1 = L2
I1 w1 = I2 w2
I x 8.37 = I / 3.5 x w2
w2 = 29.3 rad/s
