Atomic bomb:
Pro: It helps keep countries at peace due to fear of destruction
Con: Very deadly and can destroy many people's lives.
Answer:
the ratio of protons to neutrons
Explanation:
Nuclear stability is based on the ratio of protons to neutrons. The nuclear space is made up of protons and neutrons that occupies the nucleus of an atom.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures the stability of the nucleus.
For sodium, Na, the neutron/proton ratio for stability is 12/11.
Any nucleus with a neutron/proton combination different from its stability ratio will be unstable.
Answer:
The frictional torque is
Explanation:
From the question we are told that
The mass attached to one end the string is
The mass attached to the other end of the string is
The radius of the disk is
At equilibrium the tension on the string due to the first mass is mathematically represented as
substituting values
At equilibrium the tension on the string due to the mass is mathematically represented as
The frictional torque that must be exerted is mathematically represented as
substituting values
I think it’s mechanical waves..
Answer:
Explanation:
Natural length of the string is given as
length of the string while block is hanging on it
extension in length is given as
now we have strain in the string is given as
similarly we will have cross-sectional area of the string is given as
now the stress in the string is given as
Now Young's Modulus is given as
