They do not change the nature of the substance unless a chemical change occurs along with the physical change. These may be irreversible, but the result is still composed of the same molecules. When you cut your hair, that is a physical change, even though you can't put the hair back on your head again
Answer:
covalent bonds
Explanation:
Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.
(if it is still confusing i have another way of explaining so jus let me know :)
Answer:
D. The telescope detects high-energy electromagnetic waves.
Explanation:
First of all, let's define what X-rays are.
X-rays are electromagnetic waves at high frequency and short wavelength.
The wavelength of X-rays span between 0.01 and 10 nanometers. X-rays are the second-highest frequency electromagnetic waves, after gamma rays, which have higher frequency.
The energy of an electromagnetic wave is directly proportional to its frequency, according to the equation:
where:
h is the Planck constant
f is the frequency of the wave
Since X-rays are high-frequency electromagnetic waves, it means that they also are high-energy electromagnetic waves.
Therefore, the correct answer is
D. The telescope detects high-energy electromagnetic waves.
