To answer this question, we must bear in mind the following considerations that are mentioned in the statement:
The cannon balls are identical and shoot with the same force
The force acting on the cannonball increases with the length of the hole.
You want to know which cannon will have the least momentum on the ball.
Then, the force on the ball increases as the barrel length increases and the impulse depends on the magnitude of the force, then, the cannon that will have the minimum impulse will be the 1 meter one.
The answer is option B.
Answer: See explanation
Explanation:
1. The collective name given to protons, neutrons in the nucleus of an atom is referred to as the nucleon.
2. The mass number simply means the total number of both the protons and the neutrons that we have in a nucleus.
3. Atomic number = Protons = 28
Mass number = 64.
Neutron = Mass Number - Protons
Neutron = 64 - 28 = 36
4. The number of Protons is also the number of atomic number which is 28.
Answer:
- <u>C = Q/∆V . So the overall strategy here is to find the potential difference ∆V corresponding to a particular Q on an object, then take the ratio.</u>
Explanation:
Capacitance is the amount of charge something can hold for a given ap- plied potential difference between separated parts of the conductor:
Answer:heed
Explanation:
heed knows how to divide.
The answer is:
noble gases will not form compounds.
The explanation:
-The noble gas family, all of the elements in Group Zero.
-The list of noble gases include helium(He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
- these elements don't like to react, we don't use them because of they have 8 valence electrons already and don't like to lose or gain electrons so, they will not form compounds.
