Which of the following strategies can earth's coal supply last longer? a. replant diminishing forests b. install scrubbers in power plants c. capture and store carbon d. teach the public energy conservation

D. Teach the public energy conservation

Coal is an efficient and inexpensive source of energy which provides a stable and large scale energy generation in the form of electrical and thermal energy. It is a type of fossil fuel which is most abundantly present. But it is also a non- renewable source of energy, and cannot be replenished after a single use. It is used as a source of generation of electricity, production of metallic objects,  manufacturing of a liquid fuel, engines of local trains and for other purposes. As, it is a non- renewable resource it should be used in a sustainable way.

Hence, D. Teach the public energy conservation is the correct option.

a and c

explanation:

both a and c are correct answers to my knowledge, it's been a bit since i've done anything related to magnetic fields, but it should be right.

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
