One of the main characteristics of the lever is that it allows the multiplication of effort, that is, increasing the ability to perform work with less physical effort. This occurs due to the mechanical properties of the lever, such as the balance of moments and the action-reaction principle. When we apply a force on the lever to perform work, what will be the result?a.
The result will be a lower speed to perform the work.
b.
The result will be a greater force exerted on the object to perform the work.
c.
The result will be a smaller force exerted on the object to perform the work.
d.
The result will be a greater speed to perform the work.
e.
The result will be that nothing will happen, as no force was applied.

Imagine that our body is like a very large city, and the blood needs to reach all parts of this city to deliver oxygen and nutrients. The circulatory system is like the road network of this city, with the heart being the central pumping station and the veins and arteries being the avenues and streets through which the blood travels. Based on what you have learned about the circulatory system, explain how the heart, veins, and arteries work together to circulate blood through the body and mention at least one important function of each of these components.
