Why does refraction occur simple? Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different […]
Why do mirror images look better?
When was the first robot created?
When was the first robot created? 1950s Who first used the word robot? Karel Čapek Is Alexa a robot? Instead of a physically present robot, Alexa would be an omnipresent AI assistant that would be incorporated into all of your devices and would be able to take and execute commands to each specific device. From […]
How do you calculate the wavelength of water?
How do you calculate the wavelength of water? Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda λ, so λ = v/f. How is wave steepness measured? The wave steepness is defined as the ratio of […]

Is kinetic energy proportional to temperature?
Is kinetic energy proportional to temperature? The physical behaviour of gases is explained by the kinetic molecular theory of gases. The number of collisions that gas particles make with the walls of their container and the force at which they collide determine the magnitude of the gas pressure. Temperature is proportional to average kinetic energy. […]
Under what condition torque on current loop is zero?
What are the four strokes of an engine in the correct order?
What are the four strokes of an engine in the correct order? An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. Where is the piston on the compression stroke? The piston starts at Top Dead Center (TDC). As it travels down the cylinder, the intake valve opens. The air/fuel mixture is […]
