Answer:

20.7 billion = 20.7E9        converting to units of 10

20.7E9 km = 20.7E12 m

t = S /v = 20.7E12 m / 3.0E8 m/s = 6.9E4 s = 69000 s

69000 s = 1150 min = 19.2 hrs

Einhorn and Finkle are in a convenience store together. For a while they talk about stealing hot dogs and deodorant, for they ar
dangina [55]

We can conclude that Einhorn decides  not to steal according to the pre-conventional level where as Finkle decides per the conventional level according to Kohlberg's theory.

Explanation:

Kohlberg's theory is explained in three stages:

  1. The pre-conventional stage where sense of moral is controlled externally by rules of authority figures such as parents and teachers.An action is viewed according to the results obtained after the act.
  2. Conventional stage is when a person's morals are controlled by authority figures and their positive relation to the society norms.
  3. Post-conventional level relies on a person's principles and values where some laws are seen as unjust.

In this case, Einhorn recognizes that if you steal, you might end up being caught and punished because it is not accepted by authority figures and could led to punishment.  This is stage one. Finkle recognizes that stealing is unaccepted by the law and people in a society should avoid it.This is stage two.

We can conclude that Einhorn's decision not to steal is influenced by the pre-conventional level where as Finkle's by the conventional level according to Kohlberg's theory of moral development.

What must the condition of the alveoli be in order for gas exchange to occur
aliya0001 [1]

Answer:

There are 5 main conditions of the alveoli for proper gaseous exchange to in the lungs.

Explanation

Alveoli is found in the lungs of mammals, birds and reptiles. It is the part of the lungs where gaseous exchange really occurs.

Alveoli has a shape of that of balloon but indeed smaller than the real balloon. It allows the passage of oxygen and carbon dioxide

The five main conditions includes:

  1. The Alveoli must have large surface to volume ratio which increase the gases that could be exchanged
  2. The wall must be thin. This can shorten diffusion distance.
  3. Alveoli must be very moist so that oxygen and carbon dioxide can pass through the solution
  4. Alveoli must be well supplied with blood
  5. Alveoli must be permeable

A 2000 kg car experiences a constant braking force
Marat540 [252]
In that case, there are three possible scenarios:

-- If the braking force is less than the force delivered by the engine,
then the car will continue to accelerate, and the brakes will eventually
overheat and erupt in flame.

-- If the braking force is exactly equal to the force delivered by the engine,
then the car will continue moving at a constant speed, and the brakes will
eventually overheat and erupt in flame.

-- If the braking force is greater than the force delivered by the engine,
then the car will slow down and eventually stop.  If it stops soon enough,
then the absorption of kinetic energy by the brakes will end before the
brakes overheat and erupt in flame.  Even if the engine is still delivering
force, the brakes can be kept locked in order to keep the car stopped ...
They do not absorb and dissipate any energy when the car is motionless.
