Answer:
8 meter telescope 16 times more gather light than 2 meter telescope.
Explanation:
The amount of light gather by the telescope is known as Light Gathering Power (LGP).
Light Gathering Power is determine by the relation:
In this problem, let l₁ and l₂ be the length of two telescopes and (LGP)₁ and (LGP)₂ be the light gathering power of two telescopes respectively. Then the ratio of their LGP is :
Substitute 8 m for l₁ and 2 m for l₂ in the above equation.
Answer:
32.087 m/s
Explanation:
Velocity Initial = 5.6 m/s
time= 2.7
acceleration = 9.81
Velocity final = ?
Vf = Vi + at
Vf = (5.6) + (9.81)(2.7)
Vf = 32.087 m/s
