Alina [70]

7 m/s

Explanation:

Acceleration,

Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.

Making v the subject then

v=at+u

Taking u as zero then

The pubic symphysis connects the two hip bones anteriorly and provides a little movement during childbirth. Choose the most appr
My name is Ann [436]

Answer:

The most appropriate tissue to join the pubic symphysis -that provides resistance to pressure and stretch during childbirth- is fibrocartilage.

Explanation:

Options for this question are:

  • <em>A. Fibrocartilage.</em>
  • <em>B. Elastic cartlage.</em>
  • <em>C. Bone.</em>
  • <em>D. Hyaline cartilage.</em>

Fibrocartilage is made up of dense connective tissue rich in type I collagen fibers, hyaluronic acid and proteoglycans, which give it resistance to stretching and pressure.

Some ligaments are formed by fibrocartilage, in addition to the intervertebral discs and the junction of the pubic symphysis, allowing a certain degree of mobility to the associated structures due to their semi-elastic properties.

Hyaline cartilage, also made up of connective tissue, is less resistant than fibrocartilage.

Bone cannot form this junction, because it would not allow the relative mobility of the joint.

The elastic cartilage allows for stretching but not the strength needed to join the pubic symphysis.
