Conservation of energy explains that energy can only be transferred between different forms of energy
1 would use less energy. Please vote my answer brainliest! Thanks.
Answer:
20.6 N
Explanation:
Friction equals normal force times coefficient of friction.
F = Fn μ
On level ground, normal force equal weight.
Fn = W
Therefore:
F = W μ
F = (685 N) (0.0300)
F = 20.6 N
Power of a lens is measured by f/D ratio where f is the focal length and D is the diameter of the lens (or mirror). The ratio gives you the power of an optical device or the light gathering power. Please remember a lens focuses the light. Imagine it as a light funnel. A lens works similar to a funnel. It bends the light rays and bring them to a concentrated spot or the focus, just like a funnel that gathers a liquid and bring it out through a narrow spout. Bigger the diameter of the funnel more liquid it can handle. Same way larger diameter of the lens more light it can bring to focal point. That is how you get f/D ratio.
I hope this makes it somewhat clear?
Answer:
Assimilation refers to the process by which a person or ethnic group that constitutes a minority people imitates the culture of the majority population and, when the process is complete, completely abandons its own culture. Thus, the original cultural differences disappear and society becomes a monoculture. For example, immigrant groups or colonized indigenous peoples may abandon their culture, either spontaneously or after religious persecution and coercive measures, called assimilation policies.
A number of immigrant groups were assimilated into American society during the 19th century in what is usually described as a cultural melting pot or Americanization. In this case, the adaptation was not one-way, and largely spontaneous.
