Explanation:
motion wnergy is the sum of potential and kinetic energy
Answer:
The angle of separation is
Explanation:
From the question we are told that
The angle of incidence is 
The refractive index of violet light in diamond is 
The refractive index of red light in diamond is 
The wavelength of violet light is
The wavelength of red light is
Snell's Law can be represented mathematically as

Where
is the angle of refraction
=> 
Now considering violet light

substituting values




Now considering red light

substituting values




The angle of separation between the red light and the violet light is mathematically evaluated as

substituting values


Human dignity and worth and social justice are TWO OF THE BASIC VALUES OF THE CODE OF ETHICS FOR SOCIAL WORK.
Social workers are those professionals, who promote social change by helping to relieve hardship and suffering. Social work is committed to five basic values, which are:
1. Human dignity and worth
2. Social justice
3. Service to humanity
4. Integrity
5. Competence.
The human dignity and self worth value holds that all human beings have intrinsic value, right to well being, right to self fulfillment and control over their own lives.
The social justice value states that there should be fair and equitable distribution of resources to meet basic human needs and all citizens should have access to public resources in order to achieve full potential.
Answer:
<em>d. The sail should be reflective because in this case the momentum transferred to the sail per unit area per unit time is larger than for absorbing sail, therefore the radiation pressure is larger for the reflective sail.</em>
<em></em>
Explanation:
Let us take the momentum of a photon unit as u
we know that the rate of change of momentum is proportional to the force exerted.
For a absorbing surface, the photon is absorbed, therefore the final momentum is zero. From this we can say that
F = (u - 0)/t = u/t
for a unit time, the force is proportional to the momentum of the wave due to its energy density. Therefore,
F = u
For a reflecting surface, the momentum of the wave strikes the sail and changes direction. Since we know that the speed of light does not change, then the force is proportional to
F = (u - (-u))/t = 2u/t
just as the we did above, it becomes
F = 2u.
From this we can see that the force for a reflective sail is twice of that for an absorbing sail, and we know that the pressure is proportional to the force for a given area. From these, we conclude that <em>the sail should be reflective because in this case the momentum transferred to the sail per unit area per unit time is larger than for absorbing sail, therefore the radiation pressure is larger for the reflective sail.</em>
