B. Water molecules move from their fixed position.
C. Water molecules lose energy.
D. The temperature of the ice increases as it melts.
The answer for this question is part B that is Water molecules move from their fixed position.
This is because when water is freeze it is in a solid condition that means the molecules are held together tightly and are are vibrating in their fixed positions.
As soon as the molecules gain energy they start to move around from their fixed positions and turn into a liquid.
In the process of doing so ice melts and becomes water.
Answer: If a door is perceived as a rectangle even after being viewed from different angles, it is likely because our brain is applying a cognitive concept known as "shape constancy." Shape constancy is a perceptual phenomenon where we tend to perceive an object's shape as being consistent and unchanged, even when viewed from different angles or under varying lighting conditions.
This phenomenon occurs because our brains are constantly processing the visual information we receive and attempting to make sense of it. When we encounter a door, our brain has a preconceived notion that a typical door is rectangular in shape. As a result, even when we see the door from an angle that might distort its appearance, our brain adjusts the perception to maintain the idea that it is a rectangle.
This concept of shape constancy is a part of how our brains simplify the complex visual information we receive from the environment. It helps us recognize objects more easily and efficiently, even when they are presented in different orientations or lighting conditions.
In reality, the door may not appear as a perfect rectangle when viewed from various angles, but our brain's tendency to maintain shape constancy can override these visual discrepancies, and we continue to perceive it as a rectangle. It's important to note that this phenomenon is not limited to doors; it applies to many objects in our everyday lives, helping us make sense of the world around us.
Perception of a door as a rectangle from different angles is due to the flexibility of our visual perception, allowing our brain to adjust based on various factors. This can be observed in experiments where subjects acclimate to visual distortions over time.
When we view a door from different angles, it may still appear as a rectangle due to the way our brains perceive visual information. Our brains automatically adjust our perception based on various factors like lighting conditions, distance, and movement. This flexibility in perception allows us to make sense of the world around us. For example, in an experiment where subjects wore prism glasses to invert their visual field, initially, they perceived objects differently, but after acclimation, their perception returned to normal.

Answer:
A brush is a device which conducts current between stationary wires and moving parts, most commonly in a rotating shaft.
Answer:
The origin of science can be traced back to ancient Egypt and the Mesopotamia from about 3500 to 3000 BC. The achievements of these two civilizations in mathematics, astronomy, and medicine have reached and shaped the Greek natural philosophy in the classical era, and they usually formally try to explain events in the material world with natural causes . After the fall of the Western Roman Empire, in the first few centuries of the Middle Ages (approximately 400-1000 AD), knowledge about the ancient Greeks’ world concepts was gradually forgotten in Western Europe , while in the Muslim world of the Golden Age of Islam Was preserved in. From the 10th century to the 13th century, Western Europe retrieved the writings of ancient Greece and absorbed the research of Islamic scholars. Natural philosophy was revived, and then transformed in the scientific revolution that began in the 16th century The new ideas and discoveries during this period broke away from ancient Greek ideas and traditional methods. The rapid role of scientific method in acquiring knowledge, but the institutionalization and professionalization of science did not begin to take shape until the 19th century
2.the sun
3.Earth
4.the moon
The Sun has the greatest gravity among the listed objects because gravity is dependent on mass and the Sun has a larger mass than Earth, the Moon, or a person.
Among the given options, the object with the greatest gravity isthe Sun. Gravity is dependent on both mass and distance. The Sun has a much larger mass compared to Earth, the Moon, or a human being, hence it has the largest gravitationalforce.
As a comparison, Earth's gravity pulls us down and keeps us from floating away, but the Sun's gravity is so strong that it keeps Earth and the other planets in our Solar system in their orbits.

B. Be in phase with each other
C. Have a different frequency than the resultant wave
D. Be traveling in the opposite direction of the resultant wave
Correct answer choice is:
B. Be in phase with each other.
____________________________________________________________
Explanation:
Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.
