Which energy transformation produces electricity and is least likely to negatively impact the environment?
A) Generating electricity from a natural gas-fired power plant
B) Generating electricity from a coal-fired power plant
C) Generating electricity from a nuclear power plant
D) Generating electricity from a solar panel system
Answers
Hello!
The answer to this question is: D) Generating electricity from a solar panel system.Thank you for asking this question!
It would be greatly appreciated if you thanked me and marked me as the brainliest!
Have an amazing day.
The energy transformation which produces electricity and is least likely to
negatively impact the environment is generating electricity from a solar
panel system.
Generating electricity from solar panel involves the use of solar energy from
the sun to generate electricity . This type of energy doesn't emit any type of
harmful radiation or release toxic compounds into the atmosphere which
makes it the least likely to negatively impact the environment.
Other options emit any type of harmful radiation or release toxic compounds
into the atmosphere which makes option D the most appropriate.

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)
Answers
Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.
Answer:
A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

Combine the following ions to create neutral compounds Y3+ and OH-
Answers
Answer:
Y(OH)₃
Explanation:
Given ions:
Y³⁺ OH⁻
To find a neutral compound that conforms with the formation of the given ions;
We us the exchange of valency approach to solve this problem. The valency will form the combining power of the ions for the combination.
Y³⁺ OH⁻
Combining power 3 1
Exchange of valency 1 3
Now the compound is Y(OH)₃

What is the first stroke of a 4 stroke cycle?
A. intake
B. exhaust
C. compression
D. power
Answers
Answer:
Intake
Explanation:
It is the very first thing you do.
Figure 4: Four-Stroke Cycle In the first stroke, also known as the Intake Stroke or Induction, the piston travels from the top dead centre (TDC) to the bottom dead centre (BDC) with the intake valve open and exhaust valve closed. This creates a vacuum due to the increase in volume in the combustion chamber.
The stroke cycle is used in the operating cycle of gasoline or petroleum engines. The first stroke in the 4 stroke cycle is intake. Hence, option A is correct.
What is stroke cycle ?An internal combustion (IC) engine is referred to as having four strokes when the piston is rotating the crankshaft. A stroke refers to the whole journey of the piston along the cylinder, in either direction.
In gasoline/petrol engines, a four-stroke cycle is used. The four strokes are intake (1), compression (2), power (3), and exhaust (4). The intake port is on the right's blue side, and the exhaust port is on the left's brown side.
The piston head is surrounded by a thin sleeve called the cylinder wall, which provides a space for the combustion of fuel and the production of mechanical energy. Therefore, the first stroke of a 4 stroke cycle is intake.

A bike rider approaches a hill with a speed of 8.5 m/s. The total mass of the bike and the rider is 85 kg. Find the kinetic energy of the bike and the rider. If the rider coasts up the hill calculate the height at which the bike will come to a stop. (h=PE/mgh)
Please help me!! this is due in like 20 minutes!!
Answers
KE=3070.625 J
Height = 3.686 m
Further explanationmass of bike+rider=85 kg
velocity = 8.5 m/s
[tex]\tt KE=\dfrac{1}{2}mv^2\\\\KE=\dfrac{1}{2}\times 85\times 8.5^2\\\\KE=3070.625~J[/tex]
Conservation of energy :
(KE+PE)₁ (downhill) = (KE+PE)₂ (up the hill)
PE₁=0⇒h=0
KE₂=0⇒v=0(stop), so equation becomes :
KE₁=PE₂
[tex]\tt KE_1=3070.625\\\\KE_1=mgh_2\\\\3070.625=85\times 9.8\times h\Rightarrow h=3.686~m[/tex]
The elements mercury and bromine are both liquids at room temperature, but mercury is considered a metal, and bromine is considered a non-metal. How can that be? Explain using properties you know of.
Answers
Answer:
At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.
Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.
On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.
Explanation:
Mercury in the periodic table is Hg, and bromine is Br
