Until 1883, every city and town in the United States kept its own local time. Today, travelers reset their watches only when the

inna [77]

Answer:

135° (degrees)

Explanation:

The Earth rotates 360° in about 24 h

How many degrees in 1 hour

$360^{\circ}=24\ h\\\Rightarrow 1\ h=\frac{360}{24}\\\Rightarrow 1\ h=15^{\circ}$

So, in 1 hour the Earth rotates 15 degrees. This means that a person would have to reset their watch by 1 hour after travelling 15 degrees

In 9 hours

$9\ h=9\times 15^{\circ}=135^{\circ}\\\Rightarrow 9\ h=135^{\circ}$

So, a person would have to travel 135 degrees in order to reset their watch by 9 hours.

A wheel rotates clockwise 10 times per second. what is its angular speed answer

bogdanovich [222]

The frequency of the wheel is the number of revolutions per second:
$f= \frac{N_{rev}}{t}= \frac{10}{1 s}=10 Hz$
And now we can calculate the angular speed, which is given by:
$\omega = 2 \pi f=2 \pi (10 Hz)=62.8 rad/s$ in the clockwise direction.
