No.
Electromagnetic waves can travel without a medium.
hope this helps and have a great day :)
V1/T1 = V2/T2
Substitute the value use ratio and proportion. Use calculator.
V1 = (V2 x T1) / T2
1 is initial, 2 is final
Einstein’s Theory of Relativity was built on the research and ideas of other scientists. The Theory of Relativity proposes that the speed of light is aconstant. The statement that explains why this is considered to be a scientific theory is that the majority of the scientific community voted on this theory over other possible explanations.
Answer:
A
Explanation:
The Charles law states that the volume of an ideal gas increases when temperature is increased under constant pressure. The pressure inside the balloon is always equal to the atmospheric pressure. Therefore answer A demonstrate the Charles law.
Answer:
Covalent
Explanation:
A molecule of C₂H₅OH has C-C, C-H, C-O, and O-H bonds.
A bond between A and B will be ionic if the difference between their electronegativities (ΔEN) is greater than 1.6.

No bond has a large enough ΔEN to be ionic.
C₂H₅OH is a covalent molecule.
