Answer: Her acceleration is -0.8 m/s²
Explanation:
The initial velocity of Sandra ( u) = 10 m/s
The final velocity of Sandra ( v) = 2 m/s
Time taken by Sandra (t) = 10 s
Let the acceleration of Sandra be 'a'
Using the equation of kinematics, we have
v = u + at
⇒ 2 = 10 + 10a
⇒ -8 = 10a
⇒ 
⇒ a = -0.8 m/s²
Hence, her acceleration is -0.8 m/s².
None of the choices are correct. the kinks are caused by double bonds, which make the chain unsaturated
Answer:
Bilateral symmetry allows for directional motion. The coelom cushions organs allow freedom of motion.
Explanation:
Most animals are bilaterally symmetrical in nature with a line of symmetry dividing their body into two sides left and right sides along-with a “head” in top and “tail” in the bottom. Bilateral symmetry consisting an equal arrangement of symmetry about a vertical plane running from top to bottom.
The coelom is known as the main body cavity present in most animals. It is positioned inside the body to surrounds the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as mollusks, it is undifferentiated. In animals, it helps to allow freedom of motion.
