A star is located 9 ly away from us. What is its distance in par sec ? What is the parallax shown by this star when viewed from two locations `3xx10^(11)m` apart. Given 1 par sec `=3.084xx10^(16)m, and 1ly = 9.46xx10^(15)m.`

The nearest star to our solar system is 4.29 light years away. How mcuh is this distance in terms of par sec ? How mcuh parallax would this star show when viewed from two locations of the earth six months apart in its orbit around the sun?

The nearest star from our solar system is 4.29 light year away. How much is this distance in terms of par sec? How much parallax would this star (named Alpha Centauri) show when viewed from two locations of the earth six months apart in its orbit around the sun?

1 AU=9.46xx10^15m True/False

How many Astronomical units are there in one light year? Given Data: 1 Astronomical unit =1.496xx10^(11)m 1 light year =9.46xx10^(15)m

The avarage distance from the earth to the sun is 1.49xx10^(11) m. Find out the value of 1 par second in meter.

What is the uncertainty in velocity of an electron if the uncertainty in its position is 10^(-10) m ? Mass of the electron is 9.1 xx 10^(-31) kg and h = 6.6 xx 10^(-34) m^(2) s^(-1) ?

Let us consider that our galaxy consists of 2.5xx10^(11) stars each of one solar mass. How long will this star at a distance of 50,000 light year from the galastic entre take to complete one revolution? Take the diameter of the Milky way to be 10^5ly. G=6.67xx 10^(-11) Nm^(2) Kg^(-2). (1 ly= 9.46xx10^(15)m)
