There is no acceleration of g in the x direction because the gravitational acceleration points downward. Also, on most studies we ignore the tidal forces since we are dealing with small bodies compared to the size of the earth.

Answer:
The banking angle is 23.84 degrees.
Explanation:
Given that,
Radius of the curve, r = 194 m
Speed of the car, v = 29 m/s
On the banked curve, the centripetal force is balanced by the force of friction such that,
So, the banking angle is 23.84 degrees. Hence, this is the required solution.
Answer:
Explanation:
Electrons are allowed "in between" quantized energy levels, and, thus, only specific lines are observed. <em>FALSE. </em>The specific lines are obseved because of the energy level transition of an electron in an specific level to another level of energy.
The energies of atoms are not quantized. <em>FALSE. </em>The energies of the atoms are in specific levels.
When an electron moves from one energy level to another during absorption, a specific wavelength of light (with specific energy) is emitted. <em>FALSE. </em>During absorption, a specific wavelength of light is absorbed, not emmited.
Electrons are not allowed "in between" quantized energy levels, and, thus, only specific lines are observed. <em>TRUE. </em>Again, you can observe just the transition due the change of energy of an electron in the quantized energy level
When an electron moves from one energy level to another during emission, a specific wavelength of light (with specific energy) is emitted. <em>TRUE. </em>The electron decreases its energy releasing a specific wavelength of light.
The energies of atoms are quantized. <em>TRUE. </em>In fact, the energy of all subatomic, atomic, and molecular particles is quantized.
Answer:
All you gotta do is search it up. ask the same question you asked on here, type it into google, it'll teach you a lot more than your actual teachers.
Explanation:
Hi
only compound must two different atom.
Element have made by only single atom.
_________________________________
Compound:
A compound is formed when two or more elements chemically combine together. The elements react chemically and form chemical bonds between the atoms of the elements.
A mixture is a combination of two or more substances which are not chemically the same. ____________________________________
Homogeneous mixtures:
Homogeneous mixtures have uniform composition and appearance throughout .A homogeneous mixture is also called a true solution.
Example: sugar solution, ocean water, soft drinks, etc.
____________________________________
Heterogeneous mixtures:
Heterogeneous mixtures consist of different substances.
Examples: mixture of iron and sulphur, mixture of sand and table salt, etc.
so only elements are single atom.
all these are combination of atoms.
thanks for asking
