Are used to make images of bones inside the human body
a. gamma rays.
c. microwaves.
b. x-rays.
d. infrared waves.

The best answer is b :  X - rays

X- rays can described as powerful waves of electromagnetic energy. These waves are from the electromagnetic spectrum and their wavelength ranges between 0.01 - 10 nanometers.

They are used in various ways especially in the medical field and in security scanners at the airport.

They were discovered  by accident by a German scientist and physicist while he was working with a tube  in his laboratory.

He named them X-rays because he did not know the nature of the rays. X in  mathematics is used to designate an unknown value. 

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
