Answer:

B. The theory provides an image that humans can visualize, but it does not fully represent how electrons exist.

Explanation:

The electron cloud theory states that the electronic cloud forms a kind of unique electrosphere among all the atoms grouped in the reticulum, so that the electrons can move freely and end up stabilizing these atoms. According to such a theory, then, the free electron cloud (also called the electron sea or electron gas) works with a metallic bond, establishing the union between the metal atoms.

This proposed electronic cloud model explains some properties inherent to metals. However, it presents a limitation that an electron law would not have, because the theory provides an image that humans can visualize, but it does not fully represent how electrons exist.

The answer would be B because humans cannot see electrons so we visualize the electrons due to the theory

A horizontal force of 92.7 N is applied to a 40.5 kg crate on a rough, level surface. If the crate accelerates at 1.13 m/s2, wha
lord [1]

Answer:

The value is F_f =  46.935 \  N

Explanation:

From the question we are told that

    The  magnitude of the horizontal force is F  =  92.7 \  N

     The mass of the crate is  m  =  40.5 \  kg

     The acceleration of the crate is  a =  1.13 \ m/s

Generally the net force acting on the crate is mathematically represented as

       F_{net} =  F -  F_f =  ma

Here F_f is force of kinetic friction (in N) acting on the crate

      So  

            92.7  -  F_f =  40.5 * 1.13

=>         F_f =  46.935 \  N

The idea that the universe began from a single point and expanded to its current size explains a large number of observations, i
murzikaleks [220]
The description of the question provided above points out to the famous Big Bang Theory. In addition, this theory is among the most accepted by cosmologists because it fits like a glove to the phenomenon the universe is experiencing right now: it is expanding and distances between celestial bodies are getting farther and farther.

KonstantinChe [14]

Answer:

0.301 m

Explanation:

Torque = Force × Radius

τ = Fr

40.0 Nm = 133 N × r

r = 0.301 m

The mechanic must apply the force 0.301 m from the nut.
