The market for plywood is characterized by the following demand and supply equations: QD = 800 – 10P and QS = 50P – 1,000, where P is the price per sheet of plywood and Q measures the quantity of plywood. What is the size of the deadweight loss if the government imposes a price ceiling of $25 per sheet of plywood?

Dead weight loss-= $3750

Explanation:

QD = 800 – 10P

QS = 50P – 1,000,

At equilibrium, quantity demanded is equal to quantity supplied , so we have that, equating the two equations becomes

800 - 10p = 50p - 1000.

800 + 1000 = 50p + 10p

1800 = 60p

p = $30.

QD= QS= 800 - 10*30 = 500 units

QD= QS= 50x30 -1000= 500 units

Qd = Qs = 500 units.

When P = $25 by government putting a price ceiling, which is below the equilibrium price,it will lead to more demand than supply in the market

QD = 800 – 10P

QD= 800-10X25

QD=800-250= 550units

QS = 50P – 1,000,

Qs = 50 X25 - 1000

= 1,250-1000

QS = 250 units.

When quantity demanded =250units as a result of Quantity supplied at 250units. we will have our new price to be

QD = 800 – 10P

250 = 800 - 10p

10p = 800 -250

10p = 550

p = $55.

To calculate Dead weight Loss, we use the formulae,

0.5 x (P2 - P1) x (Q1 - Q2) where P1 and P2 are old and new prices and Q1 AND Q2 are old and new quantities

DWL = 0.5 x (55-25) X (500-250)

= 0.5 x 30x 250

Dead weight loss = $3750.

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.
