You need to subtract the atomic number from the atomic mass to find the # of neutrons.
Answer:
Option B and Option C
Explanation:
As we know that the wavelength of light is dependent on its speed. In fact the wavelength of light is directly proportional to the speed of the light. If the speed increases, the wavelength will also increase. While moving from air to acetone the speed of light reduces, and hence the wavelength reduces.
Wavelength is inversely proportional to the frequency. In acetone, the wavelength of light reduces, thus the frequency must increase and it should be higher than the frequency of light in air.
Option B and C are correct
Gamma radiation has the greatest energy<span>. This </span>is<span> because gamma radiation </span>has the highest <span>frequency. </span>Energy<span> a frequency.

Answer:
I think it is D but don't count on it
Answer:
h = 69.6 m
Explanation:
Data:
- Vo = 25 m/s
- t = 2.0 s
- g = 9.8 m/s²
- h = ?
Formula:
Replace and solve:
The building has a height of <u>69.6 meters.</u>
