What is a vernier scale ? Explain in detail .

Answer»

--⇘⇙✭ Vernier scale is a small, movable,graduated scale running parallel to thefixed graduated scale of a sextant,theodolite, barometer, etc., and used formeasuring a fractional part of one of thedivisions of the fixed scale.✭◎ The vernier is a subsidiary scalereplacing a single measured-value pointer, and has for INSTANCE ten divisions equal in distance to ninedivisions on the main scale. Theinterpolated reading isobtained by observing which of thevernier scale graduations is co-incidentwith a graduation on the main scale,which is easier to perceive than visualestimation between TWO points. Such anarrangement can GO to higher resolutionby using higher scale ratios, KNOWN as the vernier constant. A vernier may be used on circular or straight scales where a simple linear mechanism is adequate.◎ Examples are calipers and micrometers to MEASURE to fine tolerances, on extants for navigation, ontheodolites in surveying, and generally on scientific instruments.

A cyclist moving on a circular track of radius 100m completes half a velocity a revolution in one minute.what is his average velocity

Answer»

st moving on a circular track of radius 100m. (r = 100 m)Distance complete in ONE revolution = CIRCUMFERENCE of a CIRCLE{ Circumference of circle = 2πr }Distance covered by cyclist = 2 × 22/7 × 100= 4400/7= 628.57 mAlso given that, it completes the one revolution in one minute.Time (t) = 1 MIN = 60 secAverage SPEED = (Total distance)/(Total time)= 628.57/60= 10.47 m/sAverage velocity = (Total displacement)/(Total time)For circular track displacement = 0 m= 0/60= 0 m/sTherefore, the average velocity of the cyclist is 0 m/s.

A uniform disc and a hollow right circular cone have the same formula for their M.I , when rotating about their central axes .Why is it so?

Answer»

tion:Let us first TRY to find the Moment of Inertia of a Hollow right circular cone. The formula for finding the moment of inertia isI=∫ 2Mx/ (R2+H2) x R2/(R2+H2) x2 dxwhere H is the height of the cone, R is the radius and x is the small distance.When we do the integration of above EQUATION, we shall write the moment of interia as;I = 1/2MR².Now for a UNIFORM DISC, the moment of inertia is;I = 1/2πρtr⁴   = 1/2Mr².Comparing the two, we can say that a uniform disc and a hollow right circular cone have the same formula for their M.I , when rotating about their central AXES

Explain with suitable example how effect of normal force on friction forrce​

Answer»

The NORMAL force isn't NECESSARILY EQUAL to the force due to gravity; it's the force perpendicular to the surface an object is sliding on. In other words, the normal force is the force PUSHING the two surfaces TOGETHER, and the stronger the normal force, the stronger the force due to friction.HOPE THIS HELPS YOU!!!

Calculate the distance of nearest point of lightning ( speed of sound air )=346ms-1​

Answer»

tion:We have the relationship between speed, distance and time:distance traveled = speed X time takenThe units being used have to be consistent ... so to get the distance (in km) multiply the speed 346 km/h by the time TAKEN (in hours) ... also to find the distance you need to be given the other two ... both speed and time ... so you'll have to know the time from the lightning flash to when the THUNDER from it is heardThey want the nearest point where lightning struck ... the nearest point is the least distance and that will be for the shortest time ... so if they have given VARIOUS TIMES, calculate the distance traveled for the shortest time and that's the closest lightning strike.

A stone is allowed to fall from the top of tower 100 m high and at the same time another stone is projected vertically upward from the ground with the velocity of 25 matter calculate when and where two stone are meeting

Answer»

Let "t" = time after which both stones MEET"S" = distance travelled by the STONE DROPPED from the top of tower(100-S) = distance travelled by the projected stone.◆ i) For stone dropped from the top of tower-S = 0 + 1/2 (-10) t²or, S = 5t²◆ ii) For stone projected upward(100 - S) = 25t + 1/2 (-10) t²= 25t - 5t²Adding i) and ii) , We get100 = 25tor t = 4 sTherefore, Two stones will meet after 4 s.◆ ¡¡¡) Put value of t = 4 s in Equation i) , we getS = 5 × 16= 80 m.Thus , both the stone will meet at a distance of 80 m from the top of tower.PLEASE MARK THIS ANSWER AS BRAINLIEST ANSWER

What is action and reaction in person moving on a ground

Answer»

Force APPLIED by the MAN on ground is action. The equal and opposite force applied by ground is reaction. EXPLANATION:When the man moves, his feet are constantly applying force on ground. By Newton's third law, EVERY action has an equal and opposite reaction. The ground also applies equal force and in direction opposite to that of the man's feet. The feet of the man are applying DOWNWARD force and at the same time the ground is applying a force equal to that of the man and in opposite direction, that is up. This also helps them achieve a state of equilibrium. Hope this helps.
