27. A violation of the second law of thermodynamics would occur if a. a ball lying on the ground started to bounce. b. transfer of energy by heat moved energy from an object at low temperature to an object at a higher temperature. c. a refrigerator heated the air in the room in which the refrigerator is located. d. any of the above occurred. e. (a) or (b) occurred, but not (c).

( a ) or ( b) occurred but not ( c )   ( E )

Explanation:

A violation of the second law of thermodynamics would occur if a ball lying on the ground started to bounce because a ball at rest ( isolated ) system cannot have a change in position on its own over time,

Another Violation of the second law is: the transfer of energy by heat moved energy from an object at low temperature to an object at a higher temperature on its own . this is because transfer of heat energy can only occur from an object of higher temperature to an object of lower temperature unless the object is been worked on  externally

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
