<h3>What is Newton's law of gravitation?</h3>

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Given data in problem is;

The mass of Earth is, \rm m_E = 5.98 \times 10^{24} \ kg

Gravitational constant, G =6.674 × 10⁻¹¹ N m₂/kg²

The gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

\rm F_g = \frac{Gm_sm_e}{r^2}

The centripetal force due to rotation of the satellite;

\rm F_c = \frac{m_s v^2}{r}

The centripetal and the gravitational force are equal;

\rm F_g = F_c  \\\\  \frac{Gm_sm_e}{r^2} =  \frac{m_s v^2}{r} \\\\ r = G \frac{m_E }{v^2 } \\\\ r = G \frac{m_E }{(r \omega )^2 } \\\\ r = \sqrt[3]{\frac{Gm_E}{\omega^2}} \\\\ r = \sqrt[3]{\frac{6.67 \times 10^{-11}(5.98 \times 10^{24})}{(3.63 \times 10^{-4})^2}} \\\\ r = 1.44 \times 10^7   \ mm

Hence, the radius of its orbit measured from Earth's center will be 1.44 × 10⁷ mm.

Part A : A cylindrical water tank 10cm high and 520cm in diameter is filled with solution with a density of 0.75 g/cm^3
lisov135 [29]

Answer: 0.1066\ psi, 15.611\ kN

Explanation:

Given

the height of the tank is h=10\ cm

The diameter of the tank is d=520\ cm

Density of solution \rho=0.75\ g/cm^3\ or\ 750\ kg/m^3

(a) Water pressure at the bottom of the tank is

P=\rho gh\\P=750\times 9.8\times 0.1\\P=735\ Pa

1\ Pa=0.000145038\ psi

\Rightarrow P=735\ Pa\ or\ 0.1066\ psi

(b) \text{Average force on the bottom is the product of pressure and area of the base}

F_{avg}=735\times \pi \cdot (\frac{520}{200})^2\\\\F_{avg}=735\times 3.142\times 6.76\\F_{avg}=15,611.34\ N\ or\ 15.611\ kN
