Answer:

Angular speed, \omega=0.65\ rad/s

Explanation:

Given that,

Diameter of the circular ring, D = 45 m

Radius, r = 22.5 m

Let \omega is the angular speed should the ring rotate so the occupants feel that they have the same weight as they do on Earth. It can be given by providing the centripetal force to the normal force as :

mg=m\omega^2r

\omega=\sqrt{\dfrac{g}{r}}

\omega=\sqrt{\dfrac{9.8\ m/s^2}{22.5\ m}}

\omega=0.65\ rad/s

So, the angular speed of the ring is 0.65 rad/s. Hence, this is the required solution.

NISA [10]

Answer:

We show added energy to a system as +Q or -W

Explanation:

The first law of thermodynamics states that, in an isolated system, energy can neither be created nor be destroyed;

Energy is added to the internal energy of a system as either work energy or heat energy as follows;

ΔU = Q - W

Therefore, when energy is added as heat energy to a system, we show the energy as positive Q (+Q), when energy is added to the system in the form of work, we show the energy as minus W (-W).
