The correct option is;

C. 1 mile clear of clouds

Explanation:

Given that the indicated airspace location is at or below 700 feet AGL therefore, it is taken as being in the region of a class G airspace which covers the airspace regions from the base up to and equal to 1,200 feet beneath the class E airspace and the requirement for VFR flight for class G are 1 mile and clear of clouds.

A horizontal vinyl record of mass 0.10 kg and radius 0.10 m rotates freely about a vertical axis through its center with an angu
Tresset [83]

Answer:

The angular speed of the record is 3.36 rad/s.

Explanation:

Given that,

Mass of record= 0.10 kg

Radius = 0.10 m

Angular speed = 4.7 rad/s

Moment of inertia I=5.0\times10^{-4}\ kgm^2

Mass of putty = 0.020 kg

We need to calculate the angular speed

Using law of conservation of momentum

L_{i}=L_{f}

I\omega_{i}=(I+mr^2)\omega_{f}

\omega_{f}=\dfrac{I\omega_{i}}{(I+mr^2)}

Put the value into the formula

\omega_{f}=\dfrac{5.0\times10^{-4}\times4.7}{5.0\times10^{-4}+0.020\times(0.10)^2}

\omega_{f}=3.36\ rad/s

Hence, The angular speed of the record is 3.36 rad/s.
