Find the distance along an arc on the surface of the earth that subtends a central angle of 1 minutes (1 minute = 1/60 degree).
-Dominant- [34]

Answer:

1.152 miles

Explanation:

Given: central angle = 1 minute = (\frac{1}{60}) ^{o}

           radius of the earth = 3960 miles

The length of an arc = \frac{\alpha }{360^{o} } 2\pir

where: \alpha is the central angle, and r is the radius.

Thus,

Distance along the arc = \frac{\alpha }{360^{o} } 2\pir

Distance along the arc = \frac{(\frac{1}{60}) ^{o}  }{360^{o} } x 2 x \frac{22}{7} x 3960

                                      = \frac{(\frac{1}{60}) ^{o}  }{360^{o} } x 24891.4286

                                      = 1.1524

The required distance along an arc is 1.152 miles.

Describe the wave motion and mechanical wave movement of a seismic P wave 20 pts
mariarad [96]

a mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. while waves can move over long distances, the movement of medium transmission-the material- is limited. again, the oscillating material does not move far away from its initial equilibrium position ;)

A 3kg horizontal disk of radius 0.2m rotates about its center with an angular velocity of 50rad/s. The edge of the horizontal di
Lyrx [107]

Answer:

D

Explanation:

From the information given:

The angular speed for the block \omega = 50 \ rad/s

Disk radius (r) = 0.2 m

The block Initial velocity is:

v = r \omega \\ \\  v = (0.2  \times 50) \\ \\  v= 10 \ m/s

Change in the block's angular speed is:

\Delta _{\omega} = \omega - 0 \\ \\ = 50 \ rad/s

However, on the disk, moment of inertIa is:

I= mr^2 \\ \\ I = (3 \times 0.2^2) \\ \\ I = 0.12 \ kgm^2

The time t = 10s

∴

Frictional torques by the wall on the disk is:

T = I \times (\dfrac{\Delta_{\omega}}{t}) \\ \\ = 0.12 \times (\dfrac{50}{10})  \\ \\ =0.6 \ N.m

Finally, the frictional force is calculated as:

F = \dfrac{T}r{}

F= \dfrac{0.6}{0.2} \\ \\ F = 3N
