Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Distance between the two viewpoints is called Basis.

Similarly, α = d/D
Whereα = angular size of the planet (angle subtended by d at earth) and d is the diameter of the planet.αis angle between the direction of the telescope when two diametrically opposite points of the planet are viewed.

The answer seems to be different for different students. But according to my point of view if you donot only mug up things but understand carefully about the whole physical phenomena then it becomes very easy. For learning something you must see it around you. And as you know we are very fortunate because physics is going on continuously around us. So i want to say that feel the subject then i will assure you that you would surely love physics.

Vector have both direction and magnitude. And the magnitude is 1

Yogita Ingle 2 days, 7 hours ago

A unit vector is a vector of unit magnitude and a particular direction.

  • They specify only direction. They do not have any dimension and unit.
  • In a rectangular coordinate system, the x, y and z axes are represented by unit vectors, î,ĵ andk̂
  • These unit vectors are perpendicular to each other.
  • |î| = |ĵ | = |k̂| = 1

If the ice on the polar cups of the earth melts, how will it affect the duration of the day?

Well, the north polar ice cap would not have much effect, because it is floating sea ice. The ice caps that would matter are the Antarctica and Greenland ice caps. If they were to melt, days would get slightly longer (and there would be slightly fewer of them in a year). This is because the liquid water would distribute more evenly about the globe rather than all being near the poles, so the Earth's moment of inertia would increase. Since the Earth's angular momentum will not change, that means that its angular velocity (rate of turning) will decrease.
This is analogous to what happens on a playground carousel when a person standing near the axis moves outward: the rotation will slow.
This will be a very small change, as the mass of water in the polar ice caps is only a teeny tiny fraction of the total mass of the Earth.

If earth be at one half of its present distance from the sun, how many days will there be in a year?

By Keplers laws of planetary motion, we know that Tis proportional to R3

 Hence, T12 / R13  = T22 / R23  

 (T2 / T1 )2 = (R2  / R1 )3

 By the given problem, R2 is half of R1 R2 = R1/ 2

Hence,

 (T2 / T1 )2 = (R1/ 2 R1 )3 = 1/8

Substituting T1 as 1 year

T22  = 1/8 (1)2  = 1/8 (365 days)2

T=129days
