A parallel-plate capacitor that has air between the plates is initially charged by being connected to a battery. With the battery still connected, one of the following changes is made. 1: The distance between the plates is doubled. 2: A dielectric with a dielectric constant 3 times that of air is inserted, completely filling the space between the plates. 3: Another identical, but initially uncharged, capacitor is placed next to the first so they are touching, effectively doubling the area of each plate. (a) Rank these changes, from largest to smallest, based on the final potential difference across the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(b) Rank these changes, from largest to smallest, based on the final charge stored on the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(c) Rank these changes, from largest to smallest, based on the magnitude of the final electric field within the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
(d) Rank these changes, from largest to smallest, based on the final energy stored by the capacitor. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)

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!

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
