An empty semi-truck sits on the scale of a weighing station. It is then loaded with 100 irritated pigeons. These two events then

happen in sequence. a) First, the super irritated pigeons just stand on the floor of the truck. b) Second, they take flight inside the truck. They all fly in the enclosed space such that they do not collide with each other or the walls/ceiling/floor. Is the reading on the scale different in a) versus b)? Does the reading on the scale change during the transition of these events?

Answer:

The reading in the scale is going to be the same, or if it experiences some change it would be minimum. The reason is because the truck will act as a big closed cage, therefore, when the pigeons fly, the air they move with their wings in order to keep flying,  exerts the same force on the closed cage, that if they were standing on the ground.

If the truck however, allows the air flow, the weight might change, because under this scenario, the air flowing could represent less force exerted on the balance.

ryan hypothesizes that darker colors heat up faster. he places a thermometer inside a red wool sock, a green cotton glove, and a
telo118 [61]
Light are transfer through waves in the atmosphere and yes it  true that the darker the color is the more heat it could absorb thus it is also explain that the lighter the color is the less heat or light its absorb its because the light is bounces back through other form of light and it lessens the amount of heat in a substance. In Ryan's procedure the possible wrong that he done is the present of a green cotton glove. Green color are one of the color that bounces light and could not support the hypothesis of Ryan and the possible temperature he could get is not the accurate one.

Sup Milk,

Sublimation = Energy is absorbed and a solid turns to a gas.

Condensation = Energy is released and a gas changes to a liquid.

Evaporation = Energy is absorbed into a liquid to turn it into a gas.
