Physics Questions

The inside of the bulb being a vacuum, the outside air rushes in when the bulb is broken. The vibrations of the rushing air molecules produce the sound.

Low Voltage Cables are used to supply power for use up to 1.1 kV.

Mixing of blue and yellow colors make Green Color.

RYB (an abbreviation of red–yellow–blue) is a historical set of colors used in subtractive color mixing and is one commonly used set of primary colors. It is primarily used in art and design education, particularly painting.

RYB predates modern scientific color theory, which has determined that cyan, magenta, and yellow are the best set of three colorants to combine, for the widest range of high-chroma colors.

A skid happens whenever the tires lose their grip on the road. Braking skids occur when the brakes are applied so hard that the front or rear wheels lose traction.

The green house effect. The waves of smaller wavelength from the sun enter inside the car through the glass windows and are absorbed. The waves of larger wavelength emitted from inside cannot get out through the glass, but remain inside and make it terribly hot.

A physical hazard is defined as "A factor within the environment that can harm the body without necessarily touching it."

Vibration and noise are examples of physical hazards.

Physical hazards include but aren't limited to electricity, radiation, pressure, noise, heights and vibration amongst many others.
