Gravitational force or gravitational pull involves the attraction between objects with mass
This is unclear. What are the objects? Is it a balloon? A rubber ball?
Accuracy describes how close a measurement is to the truest value while precision shows how close the measurements are to one another when repeated analysis of the same measurements are performed. Precision most likely is free from any any variation.
<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
Sound travels fastest through matter in the <em>solid state</em>.
I know this from having answered a huge number of Brainly questions that required me to look up things like this:
-- Speed of sound in air . . . about 340 m/s
-- Speed of sound in sea-water . . . about 1,500 m/s
-- Speed of sound in steel . . . about 5,960 m/s
