In order to find the solid, you would want the object in which sound travels the fastest
In this case, since in object C, the speed of sound is the fastest, it is the most likely to be a solid
So object C is most likely to be a solid
Answer:
Firstly, we can state that the net force is the sum of all forces acting upon the object. Since the object is stationary, by Newton's First Law we can conclude that the sum of all forces acting upon a stationary object is 0 because there are no forces acting upon the object.
Explanation:
Please support my answer.
Answer:
4.78 m/s^2
Explanation:
A)From he FBD
we can write
Tcosθ= mg
Tsinθ= ma
dividing we get tanθ= a/g
a= g tanθ
a= 9.81 tan26°= 4.78 m/s^2
Parallax angles of less than 0.01 arcsec are very difficult to measure from Earth because of the effects of the Earth's atmosphere. This limits Earth based telescopes to measuring the distances to stars about 1/0.01 or 100 parsecs away.
