Acceleration: How long will it take a cyclist

Biology
1 answer:
melisa1 [442]3 years ago
8 0

Answer:

It will take 27 seconds for a cyclist to stop completely.

Explanation:

Initial velocity of the cyclist= u = 13.5 m/s

Acceleration of the driver = a  = -0.50 m/s^2

Final velocity of the cyclist = v = 0

Duration of time in which 13.5 m/s velocity is changed to 0 = t = ?

Using first equation of motion:

v = u + at

0 =13.5 m/s+(-0.50 m/s^2)\times (t)

-13.5 m/s=-0.50 m/s^2\times t

t=\frac{-13.5 m/s}{-0.50 m/s^2}=27 s

It will take 27 seconds for a cyclist to stop completely.

How fertilization occur in flowering plant​
Ghella [55]
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.

explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.

Adherens junctions ______________________. (a) can be used to bend epithelial sheets into tubes. (b) are most often found at the
Paladinen [302]

Answer:

(a) can be used to bend epithelial sheets into tubes.

Explanation:

The adherens junctions are cell-cell adhesions localized in places exposed to abrasion or mechanical stress, close to the apical membrane in epithelial cells is one of these locations. Some of their functions are the initiation and stabilization of cell-cell adhesion, <em>they join the actin cytoskeleton to the plasma membrane to form adhesive contacts between cells that contribute to the folding and bending of epithelial sheets,</em> therefore they can mediate adhesion and signaling.

I hope you find this information useful and interesting! Good luck!
