Radio waves are neither Longitudinal or transverse.

Only mechanical waves are either transverse or longitudinal. Examples are Ocean waves, Earthquake waves, and sound waves.

Radio waves are light waves, which means they do not require a medium to travel through.

Suppose there was a star with a parallax angle of 1 arcsecond. How far away would it be? Select all that apply.

lesya692 [45]

Answer:

option E

Explanation:

given,

Parallax angle(d) = 1 arcsecond

using Parallax formula

$d = \dfrac{1}{p}$

p is the parsecs angle which is measured in 1 arcsecond

d is the distance in parsec

now,

$P = \dfrac{1}{d}$

$P = \dfrac{1}{1}$

$P = 1 \ parsec$

we know,

1 parsec = 3.26 light year

hence, the answer will be option E

Consider a motor that exerts a constant torque of 25.0 N⋅m to a horizontal platform whose moment of inertia is 50.0 kg⋅m2 . Assu

Step2247 [10]

To solve this exercise it is necessary to apply the concepts related to Work and Kinetic Energy. Work from the rotational movement is described as

$W=\tau \Delta\theta$

In the case of rotational kinetic energy we know that

$KE = \frac{1}{2}I\omega^2$

PART A) $\theta$ is given in revolutions and needs to be in radians therefore

$\theta = 12rev(\frac{2\pi rad}{1rev})$

$\theta = 24\pi rad$

Replacing in the work equation we have to

$W=\tau \Delta\theta$

$W= (25)(24\pi)$

$W = 1884.95J$

PART B) From the torque and moment of inertia it is possible to calculate the angular acceleration and the final speed, with which the kinetic energy can be determined.

$\tau = I \alpha$

Rearrange for the angular acceleration,

$\alpha = \frac{\tau}{I}$

$\alpha = \frac{25}{50}$

$\alpha = 0.5rad/s$

From the kinematic equations of angular motion we have,

$\omega_f^2=\omega_i^2+2\alpha\theta$

$\omega_f^2=0+2*0.5*24\pi$

$\omega_f=\sqrt{0+2*0.5*24\pi}$

$\omega_f = 8.68rad/s$

In this way the rotational kinetic energy would be given by

$KE = \frac{1}{2}I\omega_f^2$

$KE = \frac{1}{2}(50)(8.68)^2$

$KE = 1883.56J$
