Newton's Law of Gravitation states that two bodies with masses m1 and m2 attract each other with a force F, where r is the distance between the bodies and G is the gravitational constant.

F=G m1m2/r2

Use Newton's Law of Gravitation to compute the work W required to propel a 1400 kg satellite out of the earth's gravitational field. You may assume that the earth's mass is 5.98✕1024 kg and is concentrated at its center. Take the radius of the earth to be 6.37✕106 m and G = 6.67✕10-11 Nm2/kg2. (Round your answer to three significant digits.)

The workdone is  

Explanation:

From the question we are told that

    The equation for the force is  

     The gravitational constant is

     The mass of satellite is  

      The radius of the earth is  

        The mass of earth is  

Generally the work required is mathematically represented as

Where  b =  G this is because the satellite has to overcome the earth gravitational pull

 And  a  =    this because at infinity the there is not effect of gravitational force

        So

  substituting values

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
