Centrifugal force with a beaded chain
Secure a length of beaded chain like that frequently used for pull cord on electric light switches or for key chains. Fasten the ends together to make a ring. Join this to the string from the drill and view the effects of centrifugal force.
An engineer is using DSC to determine the fiber volume fraction of a carbon fiber / epoxy prepreg. It is known that the heat of reaction of the pure, fresh epoxy resin (no carbon
calculate the acceleratio due to gravity on planet mercury if mass = 2.99 x 10 9to the power 23)kg and radius = 2.42 x 10( to the power 6) metres.
Light is normally incident on a thin soap film and is reflected. If the wavelength of this light is "L" and the index of refraction of the soap film is "N", complete destructive i
Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'. Nuclei
Beat period : The time interval among two successive beats is called as beat period. Beat frequency : The number of beats given per second is called as beat frequency.
Define the Critical Angle and Fiber Optics When light is traveling in an optically dense medium, like water, and comes to the boundary of a less dense medium, like air, there a
Explain about the total internal reflection. Total internal reflection: While light is incident onto a medium of lesser index of refraction, ray is bent ahead of the norma
