Answer:
The following are the relationship between dehydration reactions and hydrolysis:
1. Dehydration reactions can occur only after hydrolysis.
2. Dehydration reactions ionize water molecules and add hydroxyl groups to polymers while hydrolysis reactions release hydroxyl groups from polymers.
3. Dehydration reactions assemble polymers, and hydrolysis reactions break down polymers.
4. Hydrolysis creates monomers, and dehydration reactions break down polymers.
5. Dehydration reactions eliminate water from lipid membranes, and hydrolysis makes lipid membranes water permeable.
The answer is that it is an elastic collision.
<u>Explanation:</u>
When two objects come in direct contact with each other, the collision occurs. It is the event in which two or more bodies exert forces on each other in about a relatively short time.
As a result of a collision, No losses in the kinetic energy.
The formula for an elastic collision of momentum is given by
m1u1 +m2u2 = m1v1 + m2v2
where m1,m2 represents the mass of 1st and 2nd body
u1, u2 represents the initial velocity of the first and second body
v1, v2 represents the final velocity of the first and second bodies.
During a collision, the kinetic energy before the collision will be equal to the kinetic energy after the collision.
Smaller the force, greater the collision acting upon the object.
Answer:
400X
Explanation:
Total magnification = power of eyepiece (ocular) × power of the objective lenses
= 10X × 40X = 400X
Answer:
Given: m = 5 kg, r =1 m, ω = 2 radian/s, centripetal force = ?
Formula : Centripetal force = mv²/r = mrω²
(Since v = r ω)
Put the values.
Answer:
The initial velocity of the water from the tank is 5.42 m/s
Explanation:
By applying Bernoulli equation between point 1 and 2
At the point 1
P₁=0 ( Gauge pressure)
V₁= 0 m/s
Z₁=3 m
At point 2
P₂=0 ( Gauge pressure)
Z₂= 0 m/s
Now by putting the values
V₂= 5.42 m/s
The initial velocity of the water from the tank is 5.42 m/s
