To find the area of a circle, use the formula: A = \pi r^2 where: (A) is the area, (\pi) (pi) is approximately 3.1416, (r) is the radius (the distance from the center of the circle to its edge). Example: If (r = 5), A = pi (5)^2 = 25pi \approx 78.54

The absolute threshold is the minimum amount of stimulation needed for a person to detect a stimulus 50% of the time (e.g., the faintest sound you can hear). The difference threshold (or just noticeable difference) is the smallest change in a stimulus that can be detected 50% of the time (e.g...

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed or transferred from one form to another. The total amount of energy in a closed system remains constant, even though energy may change forms—for example, from kinetic to potential or to heat.

The three main parts of a nucleotide are: Phosphate group – links nucleotides together to form the backbone of DNA or RNA. Five-carbon sugar – either deoxyribose (in DNA) or ribose (in RNA). Nitrogenous base – a molecule containing nitrogen; it can be adenine, thymine, cytosine, guanine, or...

The Doppler Effect is the apparent change in frequency or wavelength of a wave when the source or observer is moving. As the source approaches, waves are compressed, creating a higher frequency or pitch. When it moves away, waves are stretched, producing a lower frequency. It applies to sound...

Aphrodite’s weaknesses include vanity, jealousy, and a tendency toward infidelity. She often acts impulsively, driven by desire rather than reason. Her beauty makes her prideful, and her emotions—especially love and envy—can cloud her judgment and cause conflict among gods and mortals.
