An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal.

You will need to use the Momentum Principle to do the first part of this problem, and the Energy Principle to do the second part
My name is Ann [436]

Answer

given,

Mass of satellite, m = 4500 kg

Mass of the earth, M = 6 x 10²⁴ Kg

Earth circular orbit radius, R = 9.3 x 10⁶ m

a) To find the speed of the satellite

   we need to equate the gravitation force between earth and satellite with the centripetal force.

\dfrac{GMm}{R^2}=\dfrac{mV^2}{R}

V = \sqrt{\dfrac{GM}{R}}

V = \sqrt{\dfrac{6.67\times 10^{-11}\times 6\times 10^{24}}{9.3\times 10^6}}

   V = 6559.89 m/s

b) Minimum amount of energy of satellite

    E = \dfrac{GMm}{r}-\dfrac{1}{2}mv^2

    E =\dfrac{6.67\times 10^{-11}\times 6\times 10^{24}\times 4500}{9.3\times 10^6}}-\dfrac{1}{2}\times 4500\times 6559.89^2

           E = 9.68 x 10¹⁰ J

Minimum amount of energy require to move satellite is equal to E = 9.68 x 10¹⁰ J

On average, how many stars would we have to search before we would expect to hear a signal? assume there are 500 billion stars i
Keith_Richards [23]

We would have to search at least 5,000,000,000 (5 billion) stars before we would expect to hear a signal.

To find out the number of stars that we will need to search to find a signal, we need to use the following formula:

  • total of stars/civilizations
  • 500,000,000,000 (500 billion) stars / 100 civilization = 5,000,000,000 (5 billion)

This shows it is expected to find a civilization every 5 billion stars, and therefore it is necessary to search at least 5 billion stars before hearing a signal from any civilization.

Note: This question is incomplete; here is the complete question.

On average, how many stars would we have to search before we would expect to hear a signal? Assume there are 500 billion stars in the galaxy.

Assuming 100 civilizations existed.

Explain which is more accurate: measuring to the nearest centimeter or to the nearest half inch?
blagie [28]
Thank you for posting your question here at brainly. 

1 inch = 2.54 centimeters 
<span>Thus; 1/2 inch = 1.27 centimeters </span>
<span>Therefore; measuring to the nearest centimeter is more accurate than to the nearest half-inch. 
</span>
I hope the answer will help you. Please feel free to ask more questions. <span />
