a) inertia of directionExplanation:Inertia of DIRECTION is DEFINED as the inability of an object to change its motion unless acted upon by an external force.Here the coin FLIES when the external CENTRIPETAL force of the tables exerts force on it. The coin OFFERS its interia in the form of friction but when the centripetal force is more, it makes the coin fly tangentially

An OPTICAL medium is MATERIAL through which ELECTROMAGNETIC WAVES propagate. It is a form of transmission medium

Explanation: When the image of an OBJECT is ERECT but is INVERTED in the lateral side it is called lateral inversion i.e the LEFT side comes to the right and the right comes to the left. It is due to direction that light FOLLOWS when it strikes a reflecting surface, generally a mirror.

18 m per secExplanation:we have V = U + At ; V= final-velocity U = initial-velocity A =acceleration and t is timeso as STARTING fro the rest so U is zero so ;V = 0 + 6 x 3    = 18 so the SPEED is 18 meter per SECOND   please mark as brainiest

here is your answer Two practical applications of REFLECTION of sound WAVES: (i) Hearing aid: It is a device used by the people who are hard of hearing. Here the sound waves, which are received by the hearing aid are reflected into a narrower AREA leading to the EAR. (ii) Sound boards: Curved SURFACES can reflect sound waves.

There are 5 RESISTORS .Each Resistance is of 1/5 ohms_________________To Find :MAXIMUM Resistance ________________Solution :For minimum VALUE of the resistance ADD all the resistors in series combination.

A wind energy conversion SYSTEM is an apparatus for converting the kinetic energy available in the wind to mechanical energy that can be used to power MACHINERY (grain mills, water PUMPS, etc) and/or to OPERATE an electrical generator. ... The average availability of commercial wind power plants is now around 98%.

is is due to INERTIA of DIRECTION.When a the coin is PLACED on the revolving table , the coin stays on the table because of the force of friction between the coin and the table. This frictional force balances the centrifugal force of the table .When the centrifugal force becomes greater than the frictional force , the coin flies off tangentially due to inertia of direction as the coin has the tendency to regain its natural straight LINE path.

the question is not in agreement with the figure. But fortunately I can explain you the way the question in the figure can be done.both 4 ohm and 8 ohm are in series. let us CALL it Xboth x ohm and 5 ohm are in series. let us call it YWe can see X and Y are in parallel connection. 1/X + 1/Y is the EQUIVALENT resistance, which will already be GIVEN in the question. Read and calculate accordingly.

Frequency describes the number of waves that PASS a fixed PLACE in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. ... Usually frequency is measured in the hertz unit, NAMED in honor of the 19th-century German PHYSICIST HEINRICH Rudolf Hertz.

1.) It has a capillary tube that contains mercury or colored alcohol. 2.) A bulb that one places onto a surface to MEASURE the temperature of the body is the other part.3.)HIGH ACCURACY and fast response

the MELTING and boiling point of iron is more than SODIUM because iron is more HEAVIER than sodium

If ELECTRIC appliances are connected in series then , if FIRST appliance is FUSED then after those appliances are connected they stop WORKING. And curent is ALSO not reached to the appliances.

In a bounded MEDIUM, standing WAVES occur when a wave with the correct wavelength meets its reflection. The INTERFERENCE of these TWO

The gravitational forces between the two objects is NEWTONS law of universal gravitation.Explanation:Newton's law of universal gravitation is usually STATED that every particle attracts every other particle in the universe with a force which is directly PROPORTIONAL to the product of their MASSES and inversely proportional to the square of the distance between their CENTERS.

A PROGRESSIVE SOUND wave is PRODUCED in the surrounding air having a frequency equal to that of the STATIONARY wave in the string. ... ACCORDING to the law of transverse vibration of stretched string, the fundamental frequency is inversely proportional to the square root of the mass per unit length.

0.25Explanation:TOTAL height = 5CM.........1NO. of coins = 20.............2thickness. = 1/2 =5/20=0.25cm

DEPENDSExplanation:Given :-Length = 1.5 mBreadth = 1mHeight = 0.5mMass = 300kgI will be assuming g = 9.8 m/s^2The pressure at the bottom surface of the block depends on how the block is kept.If the Length and breadth sides of the block are in CONTACT with the table,then Area in contact = 1.5 x 1= 1.5 m^2Force = mg = 300 x 9.8= 2940 N Average pressure = Force / Area = 2940 / 1.5= 1960 Pa If the Length and HEIGHT sides are in contact with the table, thenArea in contact = 1.5 x 0.5= 0.75 m^2Force = 2940 N Average pressure = 2940 / 0.75= 3920 Pa If the breadth and height sides are contact with the table,then Area in contact = 1 x 0.5= 0.5 m^2Force = 2940 NAverage pressure = 2940 / 0.5= 5880 N

plz thank my ANSWERS ALSO MAKE my answers as brainlist

Explanation:The lower wattage bulb has HIGHER resistance because the resistance of the bulb is inversely proportional to the wattage of the bulb. THEREFORE, the 40 WATT bulb has higher resistance than the resistance of the 60 watt bulb

useful electricpower and heat OUTPUT PER fuel ENERGY consumed. Same as the THERMAL EFFICIENCY.

The 2-speed AXLE WORKS on the same basic PRINCIPLES, but with an added planetary gear set inside the ring gear. ... This forces the planetary gears to rotate on the inner ring gear teeth. The planetary gears rotate on the CLUTCH gear at 1/3 of the ring gear speed

Hi mate. This is based on ideal gas law PV=nRT.Where P is pressure, V is VOLUME, R is gas constant and T is temperature. Hence from LIQUID to solid or solid to liquid the transition has to cross the GREY zone.This grey zone transition is is very crucial which includes the inter molecular forces acting on the molecules and each atoms which makes the change in state from hot to cold and cold to hot.The best example is ice crystal formation and WATER formation from ice crystal .Hence the inter molecular force of attraction happens to be involved with changes in grey zone.Hope it helps you mate. please thank and mark my answer as BRAINLIEST. humble request.... ✌@ ANUSHA ❤✌

i DONT KNOW the ANSWER THANKS

ear bicycle - Wikipedia One of the perceived main attractions of a fixed GEAR bicycle is LOW weight. Without the added parts required for a fully geared drive train—derailleurs, shifters, cables, cable carriers, multiple CHAIN rings, freewheel HUB, brazed-on MOUNTING lugs—a fixed gear bicycle weighs less than its geared equivalent.

Dispersion is an effect where different FREQUENCIES have a different refractive index and hence a different speed.If multiple waves are sent at different frequencies at the same MOMENT then when they ARRIVE they will not all arrive at the same moment.So the wave is spread over time and less of it is AVAILABLE at any given moment.ie there is a loss of signal power at any given instant.Explanation:your problem's solution here.
