Explanation:
Measurement plays an important role in our daily lives because they are useful to do basic tasks, such as taking the temperature of a child with the help of a thermometer,making time estimations,measure out medicines and find out weights, areas and volumes of different substances
The reason why it relates to the newtons 3 laws of motion because the first law of motion states that every object will stay at rest unless it's moved by an unbalanced force which is your hand. The second one states that <span> the velocity of an object changes when it is subjected to an external force meaning it's used by the equation that is commonly used for which is F=M*A. The way it relates to the second law because you are adding force some way or another, the mass is the egg and the acceleration is the drop of the egg while it free falls. And the last one, for a reaction there is always an equal or opposite reaction and the opposite reaction is the floor because it's going against the egg causing it to crack. If it was with the egg, it would have a soft, smooth landing.</span>
Answer:
c) is the right answer, since it is the only FALSE statement among the other 4 options, which are TRUE.
Explanation:
Constant "b" stands for the damping term in the oscillatorry equation, which means it is multiplying the first derivate of the movement variable, be it x (distance) or φ (for angular approaches).
Let's exclude the TRUE options:
- a) and d): A very large constant "b" means a high friction into the system, so, if "b" is large enough, it would prevent the system from oscillating (that is, from starting the movement) or, once moving, it may brake it down to zero amplitude within a finite time.
- b) Indeed, a large enough "b" value would mean a supercritical damping case, in which no oscilation takes place. The system breaks despite the real resonance values in frecuency. This means that only for damping below critical values, resonance may occur.
- e) Certainly, the friction may be between two solid bodies. In the case a solid body is inside a fluid environment (liquid or gas), "b" value is proportional to the hidrodynamic or aerodinamic resistance, respectively. This "resistance" depends, amongst other variables, on the shape (fluid distribution) and its cross-sectional area (the wider, the more resistance, the greater "b" shall be).
Finally, as exposed above, a greater "b" value involves a a higher damping, then a higher force against the movement, thus shorter times and quicker damping. This is why opcion c) is the FALSE answer, thus the correct option: it states a wrong principle, opposite to the physics.
Hope that was clear enough! Always think how to exclude answers first, and try to find any option that may be incoherent respect to other(s).
