To teach you how to find the parameters characterizing an object in a circular orbit around a much heavier body like the earth.
the motivation for isaac newton to discover his laws of motion was to explain the properties of planetary orbits that were observed by tycho brahe and analyzed by johannes kepler. a good starting point for understanding this (as well as the speed of the space shuttle and the height of geostationary satellites) is the simplest orbit--a circular one. this problem concerns the properties of circular orbits for a satellite orbiting a planet of mass m.

for all parts of this problem, where appropriate, use g for the universal gravitational constant.

a. find the orbital speed v for a satellite in a circular orbit of radius r. (express the orbital speed in terms of g, m, and r),
b. find the kinetric energy k of a satellite with mass m in a circular orbit with radius r. (express your answer in terms of m, m, g, and r).
c. find the orbital period t. (express your answer in terms of g, m, r, and pi).
d. find l, the magnitude of the angular momentum of the satellite with respect to the center of the planet. (express your answer in terms of m, m, g, and r.
e. the quantities v, k, u, and l all represent physical quantities characterizeing the orbit that depend on radius r. indicate the exponent (power) of the radial dependence of the absolute value of each. (express your answer as a comma-separated list of exponents corresponding to v, k, u, and l, in that order.

electromagnetic waves travel through space with vacuums. give me brainliest if 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!
