1. a job is done slowly, and an identical job is done quickly. which of the following is true?
a. they require the same amount of force, but different amounts of work.
b. they require the same amount of work, but different amounts of power.
c. they require the same amounts of power, but different amounts of work.
d. they require the same amounts of work, but different amounts of energy.

A job is done slowly and an identical job is done quickly then they require same amount of work, but different amounts of power.

Option B

Explanation:

Work done is the amount of force required to displace an object from its original position. So as force depends on mass of the object. The work will remain constant for doing a particular job related to same object. But power defines the work done per unit time.

So if power is increased for a given work means the time required to do that work is reduced. So if a particular work has to be performed on a same object then by manipulating the power we can change the time taken to complete that job.

So in this case for the identical job, one is completed slowly while other has been done quickly. This indicates that they required same amount of work as the kind of job is same but different amount of power depending on which the work is done fast or slowly.

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!
