Answer:

The energy conversion when a solar cell is used to light a street lamp is Option B: solar energy - electric energy - light and heat energy

Explanation:

From the 'Law of conservation' of energy, energy cannot be 'created' nor it can be destroyed. But we can convert energy from 'one form' to 'other'. The devices that transform energy from one form to another are called transducers.  

'Solar cells' also known as  the photo voltaic cells. These devices transform light energy into electrical energy directly. When these solar cells are used in a street lamp, it will convert this electrical energy into heat and light energy.

In 'The Story of an Hour," how does the plot event of Brently Mallard's supposed death
drek231 [11]

Answer and Explanation:

"The Story of an Hour" is a short story by author Kate Chopin. Mrs. Mallard is the main character, and a great deal of the story concerns her thoughts and feelings.

Her character is quickly and deeply developed through an important event: the supposed death of her husband, Brently Mallard. Only Mrs. Mallard does not know it is just "supposed". She is told it is a sure thing that her husband has died. The news is conveyed in a most careful manner since she has a heart condition that may kill her in case she receives shocking information.

<u>Upon locking herself up in her room to think and mourn, Mrs. Mallard's character undergoes a most amazing transformation. Unlike what anyone had expected, she realizes her husband's death has actually set her free. She is no longer someone's subservient wife. She no longer needs to ask for his opinion and to abide by his rules and decisions. She is her own person now, free to be and do whatever she likes. Her sister and friend are outside, thinking she is crying her eyes out, while Mrs. Mallard is in fact looking out the window, realizing the world has not stopped turning because of Brently's death. Life goes on, and so does she. She is the happiest she has ever been.</u>

Write a thesis statement on "Is time travel possible?".
kirza4 [7]
We all travel in time. During the last year, I've moved forward one year and so have you. Another way to say that is that we travel in time at the rate of 1 hour per hour.
But the question is, can we travel in time faster or slower than "1 hour per hour"? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?
It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from meeting? You would prevent yourself from ever having been born! But then if you hadn't been born, you could not have gone back in time to prevent them from meeting.
Albert Einstein
The great 20th century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing—space-time. There's a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.
Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people.
Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.5% of the speed of light (which is much faster than we can achieve now), and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.
Time traveler

So, if your journey began in 2003, it would have taken you only 5 years to travel to the year 2053, whereas it would have taken all of your friends 50 years. In a sense, this means you have been time traveling. This is a way of going to the future at a rate faster than 1 hour per hour.
Time travel of a sort also occurs for objects in gravitational fields. Einstein had another remarkable theory called General Relativity, which predicts that time passes more slowly for objects in gravitational fields (like here on Earth) than for objects far from such fields. So there are all kinds of space and time distortions near black holes, where the gravity can be very intense.
In the past few years, some scientists have used those distortions in space-time to think of possible ways time machines could work. Some like the idea of "worm holes," which may be shortcuts through space-time. This and other ideas are wonderfully interesting, but we don't know at this point whether they are possible for real objects. Still the ideas are based on good, solid science. In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built.
I am confident time travel into the future is possible, but we would need to develop some very advanced technology to do it. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy. Time travel to the past is more difficult. We do not understand the science as well.
Actually, scientists and engineers who plan and operate some space missions must account for the time distortions that occur because of both General and Special Relativity. These effects are far too small to matter in most human terms or even over a human lifetime. However, very tiny fractions of a second do matter for the precise work necessary to fly spacecraft throughout the solar system.
