The vertical displacement of the wave is measured from
the equilibrium to the crest and is called the amplitude.
Answer:
v = 29.73[m/s]
Explanation:
Kinetic energy is defined by the following equation:
![E_{k}=\frac{1}{2}*m*v^2 \\199=0.5*0.45}*v^2\\v=\sqrt{\frac{199}{0.5*0.45} }\\ v= 29.73[m/s]](https://tex.z-dn.net/?f=E_%7Bk%7D%3D%5Cfrac%7B1%7D%7B2%7D%2Am%2Av%5E2%20%5C%5C199%3D0.5%2A0.45%7D%2Av%5E2%5C%5Cv%3D%5Csqrt%7B%5Cfrac%7B199%7D%7B0.5%2A0.45%7D%20%7D%5C%5C%20v%3D%2029.73%5Bm%2Fs%5D)
Convex lenses are thicker at the centers than the edges, they are known as the converging lenses. Rays of light that pass through the lens are brought closer together (they converge). When rays of light that are parallel pass through a convex lens they are refracted, the refracted rays converge at one point called the principal focus.
Answer: Option (A) is the correct answer.
Explanation:
Since Robert has a history of depression this means that he is mostly worried about his image in his family and friends because everyone wants to look good in everybody's eyes.
Similarly, Robert also wants to be treated fairly well by everyone around him as he wants that everybody consider him normal.
Thus, Robert’s apprehension to get help is an example of a fear of being stigmatized.
Answer:
5.16 m/s
Explanation:
The tension in the string provides the centripetal force that keeps the object spinning in circular motion, therefore we can write:

where
T is the tension
m is the mass of the object
v is the speed
r is the radius of the circle
Here we have:
m = 280 g = 0.280 kg
r = L = 0.97 m (the radius of the circle is the length of the string)
The maximum tension allowed is
T = 7.7 N
Therefore, by solving for v, we find the maximum speed allowed before the string breaks:
