What is the acceleration of a body revolving in a circle at uniform speed? a. the acceleration is zero. b. the acceleration is directed tangentially. c. the acceleration is directed toward the center. d. the acceleration is directed away from the center.

The acceleration of a body revolving in a circle at uniform speed is directed toward the center. (C)  It's called "centripetal acceleration".

The acceleration is directed towards the centre when a body revolving in a circle at uniform speed.

Option C

Explanation:

When an object w=is moving with an uniform speed, its acceleration will be constant because acceleration depends upon the velocity of the object.  Also due to circular motion, the acceleration is directed towards the center point. The tangential component of the acceleration tend to be constant in this zero.

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!
