(a) The acceleration of the two block is determined as 0.93 m/s².
(b) The tension in the string is 5.78 N.
<h3>Net force on the aluminum block</h3>
The net force on the aluminum block is calculated as follows;
<h3>Net force on the copper block</h3>
The net force on the copper block is calculated as follows;
where;
- T is tension in the string
- ma is mass of aluminum
- mc is mass of copper
- g is acceleration due to gravity
Solve for T using (1) and (2)
<h3>Tension in the string</h3>
From equation (1);
T = μm_ag + m_aa
T = 0.2(2)(9.8) + 2(0.93)
T = 5.78 N

Answer:
Synthesis reaction
Explanation:
Synthesis reaction: two or more compounds combine to form one.
A + B → C
Decomposition reaction: one compound forms two or more.
C → A + B
Single replacement reaction: an element in one compound is replaced with another element.
AB + C → AC + B
Double replacement reaction: elements in two compounds replace each other.
AB + CD → AC + BD
Answer:
Part(a): The value of the spring constant is .
Part(b): The work done by the variable force that stretches the collagen is .
Explanation:
Part(a):
If '' be the force constant and if due the application of a force '' on the collagen '' be it's increase in length, then from Hook's law
Also, Young's modulus of a material is given by
where '' is the area of the material and '' is the length.
Comparing equation () and () we can write
Here, we have to consider only the circular surface of the collagen as force is applied only perpendicular to this surface.
Substituting the given values in equation (), we have
Part(b):
We know the amount of work done () on the collagen is stored as a potential energy () within it. Now, the amount of work done by the variable force that stretches the collagen can be written as
Substituting all the values, we can write
The answer is D
This is an example of Newton's third law of motion.
The active force is the fish against the water, so the reactive force would be the reverse, the equal force of the water on the fish.
