Constellations are groups of stars that form patterns in the night sky.Each constellation has a story about what it means or represents.Constellations are always changing and may form new images.Thus, the correct options for this question are A, B, and D.
What do you mean by Constellations?Constellations may be defined as clusters of stars that form a recognizable pattern and were imagined in order to construct noticeable and apparent configurations of objects or creatures in the sky, especially at night.
These groups of stars are also present in the day but they are not perceived due to the extremely high light of the sun. So, they form patterns in the night sky. These groups of stars are not specifically present as they are distributed randomly and can form new images.
Therefore, the correct options for this question are A, B, and D.

Energy Efficiency =
Useful Energy Output/Total Energy
Input x 100 (%)
If a power plant uses 100 units of
energy to create electricity and the
output is 5 units, where does the
95% of the energy input go?
A. lost as heat
B. lost as gas
C. escapes the system as potential energy
If a power plant uses 100 units of energy to create electricity and the output is 5 units, 95% of the energy input goes as lost as heat.
Could you ever create a machine where 100% of the input energy would turn into output energy?No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance.
How do you calculate the energy efficiency of a power plant?To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.

Why do the temperatures change over the months?
O A. Because the Moon is tilted on its axis, it reflects more sunlight on Earth during different times of Earth's yearly orbit.
B. Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.
O C. Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.
D. Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.
Answer:
Answer
Explanation:
B because the more the sun is titled the more heat=different season.
Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.
Why do the temperatures change over the months?The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.
This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.
Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.
Hence the correct option is D.
