The correct answer is:
B) The molecule contains different kinds of atoms.
The explanation:
The prediction about a methane molecule would most likely be made by using both the quantum model of the atom and John Dalton's model by stating that the molecule contains different kinds of atoms.
when:
The quantum mechanical model of the atom uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. So, this model is based on probability rather than certainty.
Dalton's Model of an Atom Based on all his observations, Dalton proposed his model of an atom. It is often referred to as the billiard ball model. He defined an atom to be a ball-like structure, as the concepts of atomic nucleus and electrons were unknown at the time.
Answer:
16.25 m
Explanation:
we know that the equation pf parabola
![y=kx^2](https://tex.z-dn.net/?f=y%3Dkx%5E2)
from bellow figure the coordinate of parabola is (600,65) that is y=600 and x=65
putting the the value of y and x in the equation of parabola
![65=k600^2](https://tex.z-dn.net/?f=65%3Dk600%5E2)
k=0.0001805
now the equation is
![y=0.0001805x^2](https://tex.z-dn.net/?f=y%3D0.0001805x%5E2)
we have to find the value of y at x=300m
so ![y=0.0001805\times 300^2](https://tex.z-dn.net/?f=y%3D0.0001805%5Ctimes%20300%5E2)
y=16.25 m
Change in momentum = Force* time
p=4.97N*(20.6s)
p= 102.4 Ns
Use the formula for mechanical advantage of simple machines. As for a lever, use formula below
mechanical advantage = force output/force input
where
Force input = 330 N
mechanical advantage = 1.6
substitute all the given data, we will get Force output
Force output = 528 N
