Answer:
To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y(x,t)=Asin(kx−ωt+ϕ).
The amplitude can be read straight from the equation and is equal to A.
The period of the wave can be derived from the angular frequency (T=2πω).
During the time that the pencil is exerting 50N of force on the marble, the marble is exerting 50N of force in exactly the opposite direction on the pencil. <em>(D) </em>The mass of the marble doesn't matter, and it doesn't even matter whether the marble is moving or perfectly still.
As soon as the pencil stops exerting any force on the marble, the marble immediately stops exerting any force on the pencil.
The answer to this is Chemical property.
Answer:
T = 2π√(L/g) = 2π√(0.80/9.8) = 1.79519... = 1.78 s is your closest option
