Force and Gravity, is what i think it is.
Answer:
A) 138.8g
B)73.97 cm/s
Explanation:
K = 15.5 Kn/m
A = 7 cm
N = 37 oscillations
tn = 20 seconds
A) In harmonic motion, we know that;
ω² = k/m and m = k/ω²
Also, angular frequency (ω) = 2π/T
Now, T is the time it takes to complete one oscillation.
So from the question, we can calculate T as;
T = 22/37.
Thus ;
ω = 2π/(22/37) = 10.5672
So,mass of ball (m) = k/ω² = 15.5/10.5672² = 0.1388kg or 138.8g
B) In simple harmonic motion, velocity is given as;
v(t) = vmax Sin (ωt + Φ)
It is from the derivative of;
v(t) = -Aω Sin (ωt + Φ)
So comparing the two equations of v(t), we can see that ;
vmax = Aω
Vmax = 7 x 10.5672 = 73.97 cm/s
Answer:
A short circuit is an electrical circuit that allows
Explanation:
Answer: Una onda es una perturbación que se propaga en el espacio, transportando energía pero no materia. Cuando la perturbación se propaga a través de un medio material, se denomina onda mecánica, por ejemplo las ondas generadas en la cuerda de una guitarra o sobre la superficie de un lago.
Explanation:
Answer:
The time period of the object is 0.2 seconds.
Explanation:
An object is oscillating as depicted in the expression below :
........(1)
The general equation is given by :
.......(2)
Comparing equation (1) and (2) we get :
The relation between angular frequency and time period is given by :
T = 0.2 seconds
So, the time period of the object is 0.2 seconds.
