Answer : A. Decreases to 
Explanation :
We know the relation between speed, wave length and frequency
If the wavelength is tripled, while the speed of the wave is held constant the the frequency will decreases to
So, the frequency will be decreases to
Answer:
Protium
Explanation: Protium is an isotope of hydrogen that is composed of one proton and one electron. It is the most abundant form of hydrogen.
Hi, I didn’t understand too well your question, but I hope this helps!
Archimedes principle is based on the weight of the object to push the object upward. Law of floation is the priciple which tells us about the density of the object with the liquid in which it is placed.
Answer: I looked it up and it says something about the waves traveling in a solid but I don’t know if that’s correct.
Nitrogen
Explanation:
Adding one proton to a carbon atom makes Nitrogen.
A quick introspection on atoms:
- An atom is made up of three fundamental particles.
- They are protons, neutrons and electrons.
- The protons are positively charged and the neutrons do not carry any charges.
- Electrons are negatively charged.
The difference between an atom and another is the number of protons in them. This is the atomic number.
The periodic table of element is a list of elements arranged based on the number of protons they have. Every element on the table has unique number of protons which makes it differ from another.
- Atoms do not readily lose their protons because they are held by nuclear forces in the nucleus of an atom.
When an element gains a proton, it becomes another element.
Carbon has proton number of 6
If a proton is added to it, it becomes 7
This is the proton or atomic number of nitrogen.
