The answer is:
when Bohr's original model stated that electrons were tiny little objects circling the nucleus along fixed orbits, however, this is no longer valid as we now know that rather "circling" the nucleus at confined orbits, electrons can seem to be everywhere at once
.
-So, The correct answer for this question would be QUANTIZATION OF ENERGY. The aspect of Bohr's original model of electron structure that is still included in the currently accepted theory of electron structure is the quantization of energy.
-Bohr suggested circular orbits of electrons around the nucleus of a hydrogen atom, but researches have shown that motion of the electron is not in a single plane., but it takes place in three-dimensional space. Actually, the atomic model is not flat
.
Answer:
variables on the horizontal and vertical axis (slope, outliers, +/- correlation, etc)
Explanation:
To find the velocity of the bullet just before reaching the ground, we use the formula.
Vy = Vosen (30 °) + gt (1).
For that we need to know the time it takes for the bullet to reach the ground from the moment it is fired.
For that we use the formula:
Xy = Xo + Vosen (30 °) * t + 0.5gt ^ 2 (2)
where:
Vy = Component of the speed in the y direction (vertical)
Vo = initial velocity of the bullet at the exit of the cannon
g = acceleration of gravity
Xy = vertical component of the position.
Xo = initial position.
t = time.
To find the time it takes for the bullet to reach the ground, we make Xy = 0 and clear t.
then it would be:
0 = 10 + 80sen (30 °) * t +0.5 * (- 9.8) t ^ 2.
The solution to that equation is:
t = 8.4 seconds.
We substitute that time in equation (1) and clear Vy.
We have left:
Vy = 80 * sin (30 °) + 9.8 * (8.4)
Vy = 42.38 m / s
So base on your question about the moving air and its is cycled in order to reach equilibrium the answer of the questions are the following
A. what are the two major characteristic that change when air is heated and cooled?
-temperature and molecular structure/ phase of the matter
<span>B. how does these characteristics change the movement of air?
</span>-if the air has lower temp the possibility that it will become heavier than with the higher
<span>C. what is the name of the cycle that develop during these changes? Air cycle</span>
<span>D. why do the changes you describe in part B provide an example of a cycle? because of its molecular activity will increase</span>
Answer:
P.E = 4.398 Joules.
Explanation:
Given the following data;
Spring constant, k = 71.8N/m
Displacement, x = 0.35m
To find the elastic potential energy;
The elastic potential energy of an object is given by the formula;
Substituting into the equation, we have;
Elastic potential energy = 4.398 Joules.
<em>Therefore, the elastic potential energy of the spring is 4.398 Joules. </em>
