The Jackson cross-cylinder is a lens of fundamental importance in optometry with a key role in the refraction routine. And yet it appears not to be as well understood as PERHAPS it should be. The purpose of this paper is to examine the linear optical CHARACTER of the Jackson cross-cylinder and, in particular, those properties associated with the operations performed on the lens in the refraction routine, namely flipping and turning. Corresponding to these operations in physical space are steps in an abstract space, SYMMETRIC dioptric power space. The powers of all Jackson cross-cylinders lie in the plane of antistigmatic powers in the abstract space. In particular the powers of an F Jackson cross-cylinder (for EXAMPLE, a 0.5-D Jackson cross-cylinder has 5 . 0 = F D) lie on a circle of radius F centred on null power. Flipping the lens takes one DIAMETRICALLY across the circle; turning the lens takes one around the circle at twice the rate. A subsequent paper shows how these operations work in defining the cylinder in the refraction routine.

tion:HOPE both graph helps u I know they r not good in DRAWING but they are fully CORRECT.....DEAR always remember v- t graph always show accelerationn x- t graph always show velocitylet me give u a trick to remember this learn s.....v.......a....,. it means if u r given with distance (s) then it always show its next letter i.e v which is velocity n if u r given with velocity then it givedms next letter i.e acceleration (a) hope this helps you ☺️ PLEASE follow me please mark me as brainlist dear please

Sir Isaac Newton first PRESENTED his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His first law STATES that every object will remain at rest or in uniform motion in a STRAIGHT line UNLESS compelled to change its state by the action of an external force.

Steps to Solve HOMOGENEOUS Differential EquationYou must have LEARNED to solve the differential equations in previous sections. To solve a homogeneous differential equation FOLLOWING steps are followed:-Given differential equation of the type dydx=F(x,y)=g(yx)Step 1- Substitute y = vx in the given differential equation.Step 2 – Differentiating, we get, dydx=v+xdvdx. Now substitute the VALUE of and y in the given differential equation, we getv+xdvdx=g(v)⇒xdvdx=g(v)−vStep 3 – Separating the variables, we getdvg(v)−v=dxxStep 4 – Integrating both side of equation, we have∫dvg(v)−vdv=∫dxx+CStep 5 – After integration we replace v=y/xS

∫ (1+v)/(1–2v-v²)dvLet, 1–2v-v² = z(-2 -2v )dv = dzor, -2(1+v)dv = dz∫ (-1/2)dz/z = (-1/2) LN|z| + C= (-1/2)ln| 1–2v-v²| +c [C is INTEGRAL CONSTANT]

3Explanation:PLEASE MARK as BRANLIST

There is a DIFFERENCE in resistance because resistance depends on TEMPERATURE. It is directly proportional to temperature( i.e. When the temperature increases the resistance ALSO increases ).Explanation:please MARK as branlist

6seconds Explanation:V=U+atfinal VELOCITY is EQUAL to zero -U=-gttime of FLIGHT while return t=2U/gt=2*30/10time of flight=6seconds

In Maxwell electrodynamics, Newton's third LAW does not HOLD for particles. Instead, particles exert forces on electromagnetic fields, and fields exert forces on particles, but particles do not directly exert forces on other particles. Therefore, two NEARBY particles do not ALWAYS experience EQUAL and opposite forces.hope it helpsthank you

he PEOPLE sitting in bus FALL backward when the bus suddenly starts because of the law of inertia. The bus suddenly comes in inertia of motion but the people’s BODY tend to be in rest due to inertia of rest. This is why their body fall backwards.Ans:2 The inertia of a body is directly proportional to the mass of the body.Hope it HELPS........ PLEASE mark me as the brainliest!!!!!

I THINK it is OPTION C.I HOPE this HELPS you

I don't KNOW SORRY I'm in 6TH GRADE

y=70ms^-1u = 0 m/s; s = 20 mt = 2 s We use the formula s = UT + (1/2)at^2 Substituting the values, we get a = 10 m/s2  At t = 7 seconds v = u + a t , → v = 0 + a t       = 10 X 7  → v = 70 m/s

Your ANSWER is :Explanation:18/5×5m/s2=18/25

Explanation:MAXIMUM acceleration=Aw^2where, A=amplitude and w=angular velocityTherefore putting the GIVEN VALUES,ACC.=(5CM)(10rad/s)^2 = 500 cm/s^2
