option A: the government paid private industries for goods and services.
Explanation:
Let the mass of planet and moon be Mp and Mn respectively.
And the distance between them is "r"
Then according to Newton's law of gravitation,
The force with which the planet and the moon attract esch other is
1) directly proportional to the product of their masses i.e. Mp * Mn
2) inversly proportional to the square of the distance between them i.e r ^2
Therefore,F =. G (Mp* Mn)/r^2
Where,G is gravitational constant

Answer: 2859.78 k
Explanation: By using the law of conservation of energy, the kinetic energy of the meteor equals the heat energy.
Kinetic energy = 1/2mv^2
Heat energy = mcΔθ
Where m = mass of meteor , v = velocity of meteor = 1623 m/s
c = specific heat capacity of meteor (iron) = 460.548 j/kg/k
Δθ = change in temperature of meteor = ?
From law ofconservation of energy, we have that
1/2mv^2 = mcΔθ
By cancelling "m" on both sides, we have that
v^2/2 = cΔθ
v^2 = 2cΔθ
(1623)^2 = 2× 460.548 × Δθ
2634129 = 921.096 × Δθ
Δθ = 2634129 / 921.096
Δθ = 2859.78 k
