Answer and Explanation:
The binary system is a star system about half of the star are the part of the binary system
The important binary systems are
- Visual binary : in visual binary system the two stars resolved visually with nay sort of optical device the orbit of binary orbit is very large about center of mass.
- Spectroscopic binary : in this binary system the stars are detected by close analysis of light and after detection it is found that there are two seller spectrum present instead of one.
- Eclipsing binary : eclipsing binary system is a several types of variable stars this binary system is very important in astrophysics
To solve this problem, we know that:
1 psi = 6894.76 Pa
1 lb / ft^2 = 47.88 Pa
Therefore:
a. 1500 x 10^3 Pa * (1 lb / ft^2 / 47.88 Pa) = 31,328.32 lb
/ ft^2
b. 1500 x 10^3 Pa * (1 psi / 6894.76 Pa) = 217.56 psi
The answer is D. A planet
