Answer:
The force on each wire is
Explanation:
From the question we are told that
The acceleration at which the elevator will stop is 
The weight of each section of the wire is 
Generally 
here 
are weight at each section
Generally considering the first section, the force acting along the y-axis is mathematically represented as
Here 
represents the tension on the wire at the first section while 
represents the weight of the lamp at the first section
So
=> 
=> 
=>
Generally considering the second section, the force acting along the y-axis is mathematically represented as
=> 
=> 
=> 
=>
Generally considering the third section, the force acting along the y-axis is mathematically represented as
Nuclear energy was not developed. It has existed for as long as time has existed, that is, since the big bang.
The thing that was developed was humans' ability to USE nuclear energy, to do what we want it to do, when we want it to do it.
The reason this was first developed was to bomb the holy beans out of Japan, in order to win World War II.
Today (2020), nine of the world's nations are known to have 14,285 nuclear bombs in storage, for the same general purpose. Seven of these nations are storing 1,170 of these bombs (about 8 percent), and the USA and Russia have all the rest ... 13,035 nuclear bombs.
All nine of these nations promise that they have no plan to use their bombs, they don't want to use them, it would be wrong and terrible to use them, and they will never be the first to use them, but they need to modernize their bombs so that theirs are better than anybody else's bombs, and they need to keep their bombs for as long as anybody else has any, and then maybe a little longer, just in case.
In the years after the ability to bomb the holy beans out of other people was developed, and enough equipment was built to do it 14 thousand times, the ability to use nuclear energy for other purposes was also developed. It's used now to generate electrical energy, and to do several jobs in Medical science.
Answer:
There are two methods generally used to magnetize permanent magnets: static magnetization and pulse magnetization.
