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

An element from the periodic table is shown below. What can you determine about the number of protons, neutrons, and electrons o
Musya8 [376]

Answer:

They are all the same = 8

Explanation:

Since the symbol of that atom is not give, we can infer from the given number the nature and kind of element we are dealing with.

The number 15.999 rounded up to 16 is the atomic weight of the atom also called the mass number.

Although not peculiar enough, we are certain that this atom is Oxygen.

 On the periodic table, elements are arranged based on their atomic numbers.

    Atomic number of oxygen = 8 = number of protons

For every neutral atom on the periodic table, the number of protons and electrons are the same

Atomic number of oxygen = number of protons = number of electrons = 8

 Number of neutrons = Mass number - atomic number = 16 - 8 = 8

How many total atoms are in 0.380 g of P2O5
pogonyaev
The gram formula mass of P2O5 is 31*2 + 16*5 =142. The mole number of P2O5 is 0.380/142=0.00268 mol. There is 7 atom in one P2O5 molecule. And there is 6.02 * 10^23 molecule per mol. So the answer is 1.13*10^22 atoms.
