Sandra is riding a bicycle at 10.0 meters/second. She slows down to 2.0 meters/second in 10 seconds. Her acceleration is __
Gennadij [26K]

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 = \frac{-8}{10}m/s^2

                                                   ⇒ a = -0.8 m/s²

Hence, her acceleration is -0.8 m/s².

It is possible for a baby to be born using ivf and a technique called somatic nuclear transfer. somatic nuclear transfer involve
kifflom [539]

The answer is there (3). This is because a mitochondrion has it own DNA called mitochondrial DNA. Therefore the three genetic materials from different parents (mitochondria from donor mother, DNA from biological mother and DNA from biological father) would be present in the baby. Somatic nucleus transfer is the medical procedure used when the biological mother has mitochondria disorder which she would not wish to pass to her offsprings (which are inherited maternally).
