Un carro inicia un viaje de 395 km a las 8:30 de la mañana con una velocidad media de 70 km por hora ¿a qué hora llegará a su destino?

Dos pueblos que distan de 10 km están unidos por una carretera recta un ciclista viaja de un pueblo a otro con una velocidad constante de 7 millas por segundo. Calcula el tiempo que emplea en segundos para llegar al otro pueblo.

Un avión despega de la pista después de recorrer un kilómetro de distancia con una velocidad de 110 kilómetros por hora calcular la aceleración alcanzada de el tiempo que tarda en despegar si parte de reposo.

Un automóvil que acelera durante 8 segundos alcanza una velocidad de 72 millas por segundo si parte del reposo calcular a la aceleración que lleva b el tiempo que tarda en alcanzar la velocidad de 72 millas por segundo c qué distancia recorrió si alcanza una velocidad de 95 millas por segundo.

i'm so sorry if this is wrong i'm only in 6th grade xd

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!

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

mass and volume are the answers you are looking for
