Service Pro Corp (SPC) is preparing adjustments for its September 30 year- end. For the following transactions and events, show the September 30 adjusting entries that SPC would make a. Prepaid Insurance shows a balance of zero at September 30, but Insurance Expense shows a debit balance of $2,340, representing the cost of a three-year fire insurance policy purchased on September 1 of the current year.
b. On August 31 of this year, Cash was debited and Service Revenue was credited for $ 1,500. The $ 1,500 related to fees for a three- month period beginning September 1 of the current year.
c. The company’s income tax rate is 20%. After making the above adjustments, SPC’s net income before tax is $ 10,000. No income tax has been paid or recorded.

1 . Dr Prepaid Insurance $2,275

Cr Insurance Expense $2,275

2. Dr Service Revenue $1,000

Cr Deferred Revenue $1,000

3. Dr Income Tax Expense $2,000

Cr Income Tax Payable $2,000

Explanation:

Preparation of the journal entries

1 . Dr Prepaid Insurance $2,275

Cr Insurance Expense $2,275

($2,340 - $2,340 × 1 months ÷ 36 months

= $2,340 - $65

= $2,275)

2. Dr Service Revenue $1,000

Cr Deferred Revenue $1,000

($ 1,500 × 2 months ÷ 3 months

= $1,000)

3. Dr Income Tax Expense $2,000

Cr Income Tax Payable $2,000

(.20*$10,000)

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.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
