Sarasota Company adopted a stock-option plan on November 30, 2016, that provided that 67,700 shares of $5 par value stock be designated as available for the granting of options to officers of the corporation at a price of $9 a share. The market price was $12 a share on November 30, 2017.

On January 2, 2017, options to purchase 28,600 shares were granted to president Tom Winter—14,900 for services to be rendered in 2017 and 13,700 for services to be rendered in 2018. Also on that date, options to purchase 14,600 shares were granted to vice president Michelle Bennett—7,300 for services to be rendered in 2017 and 7,300 for services to be rendered in 2018. The market price of the stock was $14 a share on January 2, 2017. The options were exercisable for a period of one year following the year in which the services were rendered. The fair value of the options on the grant date was $4 per option.

In 2018, neither the president nor the vice president exercised their options because the market price of the stock was below the exercise price. The market price of the stock was $8 a share on December 31, 2018, when the options for 2017 services lapsed.

On December 31, 2019, both president Winter and vice president Bennett exercised their options for 13,700 and 7,300 shares, respectively, when the market price was $16 a share.

Prepare the necessary journal entries in 2016 when the stock-option plan was adopted, in 2017 when options were granted, in 2018 when options lapsed, and in 2019 when options were exercised.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
