Is it true that nuclear radiation comes from the decay of atomic nuclei?
Yes, the decay of unstable atomic nuclei is the source of nuclear radiation.
Is it true that the atomic bomb couldn't exist without radioactivity?
Simply to put it Yes. Atomic Bombs is a form as Nuclear bomb and Nuclear products/elements such as Uranium 235 (a material used in a atomic bomb) emits radioactive particles. Radioactivity Particles = radioactivity.
Which Distances across the width of the MOS are more critical distances in length?
true
What is true about the distances between planets?
The distances between planets depend on where in their orbit they are.
What is one statement about nuclear energy that is not true?
It is not true that: Carbon dioxide is produced during nuclear reactor operation or during nuclear fission.
The Nuclear Regulatory Commission is responsible for stopping nuclear research in other countries true or false?
True
Is it true or false atomic bombs work by atomic fisson?
yes, both true & false. They can work either by fission or some combination of fission & fusion. Most modern nuclear bombs use both fission & fusion to optimize for mission, size, weight, cost, etc. Total yield can vary from 100% fission to more than 95% fusion.
Due to increasing nuclear charge the radii of the atoms decrease left to right across a period is that true?
yes that's true. as you go to the right in the periodic table you have more protons, but the number of energy shells remains the same so it pulls all the electrons close together (increasing nuclear charge) which decreases the atomic radius
True or false local winds are winds that blow over short distances.?
True
Is it true or false that ribosomes are permeable to the nuclear membrane?
TRUE
Is it true or false that uranium nuclei split during nuclear fission?
It is true that a uranium nucleus splits in the nuclear fission of uranium.
A nuclear reaction in which the nuclei of atoms join together is called nuclear fission.true or false?
False. Combining nuclei to form a new nucleus is called nuclear fusion. Nuclear fission is the splitting of an atomic nucleus.
