Satellite

The first missing quantity is force due to gravity, and it is 215.1 N.

The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.

<h3>Force between two masses</h3>

The force between two masses is determined by applying Newton's law of universal gravitation as shown below;

$F = \frac{GMm}{R^2}$

where;

M is mass of Earth = 5.97 x 10²⁴ kg
m is mass of the satellite
R is the distance between the satellite and the Earth
G is universal gravitation constant

<h3>First missing quantity</h3>

The first missing quantity is force due to gravity, and it is calculated as follows;

$F = \frac{(6.67 \times 10^{-11} ) \times (5.97 \times 10^{24}) \times (700)}{(36,000 \times 10^3)^2} \\\\F = 215.1 \ N$

<h3>Second missing quantity</h3>

The second missing quantity is distance between the statellite and the Earth,

$R^2 = \frac{GMm}{F} \\\\R^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})(1000)}{11,000} \\\\R^2 = 3.62 \times 10^{13}\\\\R = 6,000 \ km$

Answer:

The maximum amount that should be spent on the upgrade is $38,298,000.

Step-by-step explanation:

Let the initial purchase be <em>x</em>.

The ROI = 15% of <em>x</em> = 0.15<em>x</em>

At the end of 4 years, salvage value = 10% of <em>x</em> = 0.1<em>x</em>

<em />

Current income per day = $16 × 230 = $3680

Expected income per day = $21 × 245 = $5145

Increase in income per day = $5145 - $3680 = $1465

For 4 years (assuming a year is 365 days),

Increase in income = $1465 × 365 × 4 = $2138900

Maintenance and utility cost for 4 years = 4 × $56000 = $224000

At the end of 4 years,

ROI = $2138900 + salvage value = $2138900 + 0.1<em>x</em> - $224000

0.15<em>x</em> = $1914900 + 0.1<em>x</em>

0.05<em>x</em> = $1914900

<em>x</em> = $38298000
