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 = 
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
It will take 27 seconds for a cyclist to stop completely.
the answer to your question is chloroplast
The right option is d) bubbles
The production of bubbles when baking soda mixes with an acid such as vinegar is the observation that indicated a chemical property of the baking soda.
Baking soda (also known as sodium bicarbonate) is a nonflammable, white crystalline powder. Baking soda is odorless, and alkaline.
