Starting from rest, a disk rotates about its central axis with constant angular acceleration. In 8.00 s, it rotates 17.5 rad. Du

diamong [38]

Answer

Given,

time = 8 s

θ = 17.5 rad

initial angular velocity = 0 rad/s

Using rotational motion equation

$\theta=\omega_{0} t+0.5 \alpha t^{2}$

$17.5=0+0.5 \alpha(8)^{2}$

$\alpha = 0.546 \ rad/s^2$

a. angular acceleration $\alpha=0.546 \ rad/s^2$

b. Average angular velocity = total angle/total time taken

= $\dfrac{17.5}{8}$ = 2.187 rad/s

c. we have,

$\omega=\omega_{0}+a t$

$=0+0.546 \times 8$

Angular velocity at end of 8 seconds $=\omega=4.368$ rad/s

d. we have, additional angle in next 8 seconds:

$\theta=\omega_{0} t+0.5 \alpha {t}^{2}$

$=4.368 \times 8+0.5 \times 0.546 \times 8^{2}$

$=52.416$ rads

What is the wavelength of an earthquake wave if it has a speed of 15 km/s and a frequency of 9 Hz?

lara [203]

To calculate the wavelength, the formula to use is:

Wavelength = Speed / Frequency

Wavelength = 15 km/s / 9 Hz

Wavelength = 1.6666666667 or 1.67 km

The standard unit for Wavelength is meter so the final answer would be 1666.67 meters
