The amplitude of a wave is a measure of the energy it carries. The amplitude of a wave is the distance between the midline of a wave and its crest or trough.
Amplitude measures the amount of energy being transported by a wave. The larger the amplitude, the more the energy that a wave has.
Wave such as water waves have energy. Smaller waves have less energy because they have a smaller amplitude. Tsunamis have very high amplitudes and thus have a huge amount of energy
Missing part of the text:
"Two masses, m1 = 2.12 kg and m2 = 9.01 kg are on a horizontal frictionless surface and they are connected together with a rope as shown in the figure."
and missing figure (see attachment)
Solution:
We can write Newton's second law for the whole system m1-m2 and for m2 only (2 equations). Only one force (F) acts on the m1-m2 system, while if we consider m2 only we have two forces acting on it: F and T (tension), in the opposite direction. So, the two equations are
where a is the acceleration of the system.
From the first equation we get
and substituting it inside the second equation, we get
re-arranging, we get
Using
,
, and using the maximum value of T that is allowed not to break the rope (T=55 N), we can find the maximum allowed value for F:
Answer: I dont have a question but you have a fo.rt.ni.te pfp and Im guessing you play fort so add me my epic is qt-orange im NA_EAST
Explanation:
What are the statements? both of the objects do move attract and maybe that is the answer
