What is the angular diameter in arc seconds of a star like the sun (diameter= 1,400,000 km) located 8 light years (7.57 x 10^13

ss7ja [257]

Answer:

$\theta = 0.0038\ arc\ sec$

option c

Explanation:

given data:

Diameter of a star = 1,400,000 km

star distance from sun $= 7.57\times 10^{13} km$

we know that

Angle is given as

$\theta = \frac{d}{r} = \frac{14\times 10^5}{7.57\times 10^{13}}$

$\theta = 1.849\times 10^{-8} rad$

we know that

$1\ arc\ second = 4.84\times 10^{-6} rad$

$1 rad = \frac{1\ arc\ sec}{4.84\times 10^{-6}}$

SO, $\theta = \frac{1.849\times10^{-8}}{4.84\times10^{-6}}$

$\theta = 3.82\time 10^{-3} arc sec$

$\theta = 0.0038\ arc\ sec$

option c

Explanation:

LAMBERT CONIC CONFORMAL,

Central Meridian: -120 30 0.000,

1st Standard Parallel: 43 00 0.000

2nd Standard Parallel: 45 30 0.000

LAMBERT CONIC CONFORMAL uses the false origin as its Latitude of Projection's origin at 41 45 0.000

The origin was shifted 400, 000 meters west to put the whole state in a positive quadrant.
