Dr. Drew places a piece of lumber against a wall. The lumber is 175 meters long and makes an angle of 32 degrees against the wall. How far away in meters is the base of the lumber to the wall? What is a solid angle in physics?
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...

In physics, distance is a scalar quantity representing how much ground an object has covered during its motion. The distance a ball rolls down a hill depends on its path. 7 Length In mathematics, length can describe the size of one-dimensional figures. The length of a line segment is the...
In physics, folks tend to think of frequencies and proportions, while in ancient Greece, they had a monochord to get a grip on intervals. In psychoacoustics, people prefer the concept of difference of pitch, or just say that intervals can be added.In music cognition, we learn that tonal ...
Pitch –Pitch/Frequency in a sound wave refers to the rate of the vibration of a particular sound travelling through air. It is calculated in cycles per second. The SI Unit for Frequency is Hertz. The speed or velocity is calculated as frequency multiplied by wavelength. ...
