The correct answer of the given question above would be X-RAYS. The part of the electromagnetic spectrum that would be most helpful to enable a doctor to identify a broken bone is the use of X-rays. An x-ray is an electromagnetic wave that is able to pass through materials opaque to light. Hope this answer helps. Thanks for posting your question.

Answer:

The answer is: X-rays.

Explanation:

Doctors ask for x-rays if they think a bone may be broken.

An x-ray is a quick and painless test that generates images of the internal structures of the body, especially the bones. X-ray beams pass through the body and are absorbed in different amounts depending on the density of the material through which they pass.

The answer is: X-rays.

The new period will be 2.486 days.

<h3>What is the period?</h3>

The period is found as the ratio of the angular displacement and the angular velocity. Its unit is the second and is denoted by t. The value of time needed to complete the rotation is the total period.

Given data;

Mass of a star,m= 1.210×10³¹ kg

The time period for one rotation of the star, T = 20.30 days

D' = 0.350 D

R' = 0.350 R

From the law of conservation of angular momentum;

$\rm I \omega = I' \omega' \\\\ \frac{2}{5} MR^2 \times \frac{2 \pi }{T}=\frac{2}{5} MR'^2 \\\\ R^2 \times \frac{1}{T}= R'^2 \times \frac{1}{T} \\\\ T' = \frac{R'^2T}{R^2} \\\\ T' = \frac{(0.350 R)^2 \times 26.1 }{R^2} \\\\T' = 0.1225 \times 20.30 \\\\ T'= 2.486 \ days$
