Answer:
The deceleration of the plane is 0.25 m/
.
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = 
= -0.25
a = -0.25 m/
The deceleration of the plane is 0.25 m/.
Its interphase i think :
The meaning of Interphase is : the period of the cell cycle during which the nucleus is not undergoingdivision, typically occurring between mitotic or meiotic <span>divisions.</span>
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
• Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
• Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
The building blocks of nucleic acids is nucleotides
The Smooth Endoplasmic Reticulum has a wide range of functions in carbohydrates and lipid synthesis. Phospholipids and cholesterol are necessary for the construction of cell membranes. It serves as a transitional area for vesicles that transport ER products to various destinations. In liver cells, Smooth ER helps detoxify certain compounds. In muscle contraction, and in brain cells it synthesis male and female hormones.
