Read this excerpt from Through the Looking-Glass by Lewis Carroll.

“That would never do, I'm sure,” said Alice: “the governess would never think of excusing me lessons for that. If she couldn't remember my name, she'd call me ‘Miss!’ as the servants do.”

“Well, if she said ‘Miss,’ and didn't say anything more,” the Gnat remarked, “of course you'd miss your lessons. That's a joke. I wish YOU had made it.”

“Why do you wish I had made it?” Alice asked. “It's a very bad one.”

But the Gnat only sighed deeply, while two large tears came rolling down its cheeks.

“You shouldn't make jokes,” Alice said, “if it makes you so unhappy.”

Then came another of those melancholy little sighs, and this time the poor Gnat really seemed to have sighed itself away, for, when Alice looked up, there was nothing whatever to be seen on the twig, and, as she was getting quite chilly with sitting still so long, she got up and walked on.

Question:
How does Lewis Carroll’s use of opposites appear in this excerpt?

Answers:
1#. Alice says that her governess would never excuse her from her lessons, even if she 2#. did not have a name.

3#. The gnat jokes that Alice would have to miss her lessons if the governess called her “Miss.”

4#. The gnat makes jokes, but they seem to cause him unhappiness rather than joy.

5#. The gnat disappears after he lets out one last sigh and Alice looks up at the tree.

She was rambling on in this way when she reached the wood: it looked very cool and shady. “Well, at any rate, it's a great comfort,” she said as she stepped under the trees, “after being so hot, to get into the—into WHAT?” she went on, rather surprised at not being able to think of the word. “I mean to get under the—under the—under THIS, you know!” putting her hand on the trunk of the tree. “What DOES it call itself, I wonder? I do believe it's got no name—why to be sure it hasn't!”

She stood silent for a minute, thinking: then she suddenly began again. “Then it really HAS happened, after all! And now, who am I? I WILL remember if I can! I'm determined to do it!” But being determined didn't help much, and all she could say, after a great deal of puzzling, was, “L, I KNOW it begins with L!”

1.What is a non example of constant?
2.What is an example of constant?

Answers

Answer:

1. A non example of a constant in physics is a value that changes. For example, the temperature of Hong Kong, let's say, is not a constant, since it changes and does not stay at the same value. It gets higher in the summer and lower in the winter.

2. An example of a constant in physics would be the gravitational acceleration of the Earth. Since the Earth's mass' changes is negligible when compared with the overall mass of the Earth (unless something big happens, of course, like a meteor or asteroid), the gravitational acceleration on Earth is largely unchanged, even constant from our viewpoint.

Explanation:

Hope this helped!

Answer:

a science experiment, the controlled or constant variable is a variable that does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant. a dependant variable(opposite)would be the properties of the plants themselves, which the scientist is observing in relation to the changing light. These properties might include the plants' color, height and general health of the plant

what is santa's average speed when visiting houses if he visits 800 million houses over 48 hours?

Answers

Well, "speed" normally = (total distance covered) / (time to cover the distance).

In this case, we don't know the total distance that Santa has traveled, so the question can be answered only if we're willing to consider some other meaning of "speed".

Maybe we could say that in this case, "speed" means the average rate at which he visits houses. Then ...

Speed of visits = (total houses visited) / (time to visit them).

Speed of visits = (800 million houses) / (48 hours)

Speed of visits = 16.67 million houses per hour.

That's 277.8 thousand houses per minute

That's 4,630 houses per second

A car engine uses the combustion of fuel to move a system of gears that
move its wheels. Not all of the fuel's energy is transferred to the wheels.
Which two transformations happen to the rest of the energy?
I A. It is transformed into sound energy.
O B. It is transformed into thermal energy.
I c. It is transformed into chemical energy.
D. It is transformed into nuclear energy.
E. It is transformed into kinetic energy.

Answers

Answer:

A and B

Explanation:

When a car engine uses the combustion of fuel to move a system of gears that move its wheels,  the fuel's energy is transferred to the wheels and the rest of the energy:  is transformed into sound energy and thermal energy.  So, option (A) and (B) are correct.

What is law of conservation of energy?

Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present. The law of energy conservation is adhered to by all energy forms.

In a nutshell, the law of conservation of energy asserts that the system's total energy is conserved in closed systems, or systems that are separated from their environment.

When car engine uses the combustion of fuel to move a system of gears that move its wheels, maximum of its energy transformed into kinetic energy and rest of energy is dissipated in a form of sound energy and thermal energy. So, option (A) and (B) are correct.

A science teacher shows his students an image of a volcanic mountain range and informs them it was created by the movement of Earth’s tectonic plates. He asks his students to explain how this occurred. Which student’s explanation is best?





Student A

An oceanic plate converged with an oceanic plate. Both plates subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption which created the mountains.

Student B

A continental plate converged with a continental plate. Neither plate subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption which created the mountains.

Student C

An oceanic plate converged with a continental plate. The more dense, continental plate sank below the less dense oceanic plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.
