a satellite with a mass of 100kg fires it’s engines to increase velocity, thereby increasing the size of its orbit around the ea

rth. as a result it moves from a circular orbit if radius 7.5x10^6 m to an orbit of radius 7.7x10^6 m. what is the approximate change in gravitational force from the earth as a result of this change in the satellites orbit?

The approximate change in gravitational force from Earth as a result of the change in radius of the satellite's orbit is -95.07N

<h3>What is the universal law of gravitation?</h3>

The universal law of gravitation states that the particle of matter in the universe attracts another particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

It is written thus;

F = G M_1M_2÷ r^2

Where

F = Gravitational force

G = Gravitational constant

M_1 and M_2 are the masses of the object

r = radius

How to calculate the gravitational force

Formula:

F = G M_1M_2÷ r^2

Given M_1 = 100kg

M_2 = 5.97 x10^{24} kg

r = 7.5 x 10^6 m

G =  6.67 x 10^{-11} N-m²/kg²

For the first orbit, substitute the values

F = 6.67 x 10^{-11}× 150 ×  5.97 x 10^{24} ÷ (7.5 x10^6)^2

F = 5.95 × 10^{16} ÷ 56.25 × 10^{12}=  105.77 N

For the second orbit of radius 7.7 x 10^6 m

F =  6.67 x 10^{-11} × 100 ×  5.97 x 10^{24} ÷ (7.7 x 10^6)2

F = 5.95 × 10^{16}÷ 59.25 × 10^{12} = 200. 84 N

The approximate change = 105. 77 - 200. 84 = -95.07N

Hence, the approximate change in gravitational force from Earth as a result of the change in radius of the satellite's orbit is -95.07N

Given the following information, what is the concentration of H2O(g) at equilibrium? [H2S](eq) = 0.671 M [O2](eq) = 0.587 M Kc =
MAVERICK [17]

<u>Answer:</u> The equilibrium concentration of water is 0.597 M

<u>Explanation:</u>

Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{c}

For a general chemical reaction:

aA+bB\rightleftharpoons cC+dD

The expression for K_{eq} is written as:

K_{c}=\frac{[C]^c[D]^d}{[A]^a[B]^b}

The concentration of pure solids and pure liquids are taken as 1 in the expression.

For the given chemical reaction:

2H_2S(g)+O_2(g)\rightleftharpoons 2S(s)+2H_2O(g)

The expression of K_c for above equation is:

K_c=\frac{[H_2O]^2}{[H_2S]^2\times [O_2]}

We are given:

[H_2S]_{eq}=0.671M

[O_2]_{eq}=0.587M

K_c=1.35

Putting values in above expression, we get:

1.35=\frac{[H_2O]^2}{(0.671)^2\times 0.587}

[H_2O]=\sqrt{(1.35\times 0.671\times 0.671\times 0.587)}=0.597M

Hence, the equilibrium concentration of water is 0.597 M

What atom has 26 protons and 24 electrons
Bezzdna [24]

Answer:

iron (Fe)

Explanation:

Since an atom is electrically neutral, so the atom has 26 electrons also. Ion has 24 electrons, so it has experienced loss of 2 electrons. So, charge on ion is +2. Also, the element with 26 protons (26 atomic number) is iron (Fe).
