St. Louis, Missouri, is located near the middle of the United States. On June 21, the noon Sun rays hit St. Louis at an angle of 75°. On December 21, the noon Sun rays hit at an angle of 28°. How will this affect the temperature in St. Louis on these dates?
Answer:
The temperature will be colder on December.
Explanation:
It is given that the angle of the sun rays on June 21st on St. Louis, Missouri hits at 75° angle. And on December 21st, the sun rays are at an angle of 28°.
Now, St. Louis, Missouri is located in the middle of United States which is in the Northern hemisphere.
From here, we can conclude that the temperature of St. Louis, Missouri on December 21st will be much colder as the rays of the Sun is at a much lower angle on the surface than on the 21st June. Due to this lower angle of the sun rays, the energy of the sun will be more spread out and will be less concentrated on the surface on 21st December when compared to 21st June. Also the days are much shorter in December than in June.

Newton's second law of motion described the relationship among force, mass, and acceleration. Write the equation.
Please help me vote you brainiest
Answer:
Second Law of Motion (Law of acceleration)
- It states that the acceleration of an object equals the net force acting on the object divided by the object's mass.
To simplify, use the magic formula triangle
the units of these quantities were as follows: Force (Kilogram meter per second squared or kg m/s² which is also equivalent to one Newton, or N), mass (kilogram or kg), and acceleration (meter per second squared or m/s²).
The Formula on Law of acceleration is:
If the force is missing, Force = Mass × Acceleration or F = ma
If the mass is missing, Mass = Force ÷ Acceleration or m = F/a
If the acceleration is missing, Acceleration = Force ÷ Mass or a = F/m
A point charge is a model that represents the charge is acting uniformly Onit surroundings what other characteristic does a point charge have? A. it has no excess neutrons B. it has no excess protons and electrons C. it has no volume D. it has no Mass
Answer:it’s c
Explanation:
I just took a quiz
A point charge is a model that represents the charge is acting uniformly unit surroundings what other characteristic does a point charge have " it has no volume"
What is point charge?A hypothetical charge at a specific space would be known as a point charge. Even though an electron is often referred to as a point charge, its size might be determined by just a length scale called the electron radius.
What is charge?Wave amplitude at a specific distance is charged (r). It could be described as energy, although a force is a much more common way to do it.
A point charge is a model that represents the charge is acting uniformly unit surroundings what other characteristic does a point charge have " it has no volume"
therefore, the correct answer will be (C).

if yo divide 340m/s by 10m you get 34 and then the m/s and m ad to make m/s squared
Which of the following best describes the arrangement of electrons in a metallic bond?
-Electrons are transferred from one atom to another.
-Electrons exist as shared electron pairs between neutral atoms.
-Electrons are delocalized in a "sea of electrons" and are shared among the positively charged metal ions.
-Electrons are shared unequally, creating a bond with partial positive and negative poles.
Help ASAP please
Answer:
-Electrons are delocalized in a "sea of electrons" and are shared among the positively charged metal ions.
Explanation:
In a metallic bond, electrons are delocalized in a sea of electrons and are shared among the positively charged metal ions.
- In a metallic bond, there is delocalization of electrons. The electrons are shared in between the atoms, rather than getting transferred. So, there is no transfer of electrons.
- The electrons are delocalized and shared alongside the nuclei of the atom. There is no existence of electrons around the neutral atoms.
- In the metallic bonds electrons are delocalized and are shared among the positively charged atomic nuclei in the form of a sea of electrons. Thus, electrons are delocalized in a sea of electrons and are shared among positively charged metal ions.
- There is an equal sharing of electrons in the bond. No unequal and partial sharing is there.

An element (either a neutral atom or an ion) can be distinguished from any other element by 1. The number of electrons it has. 2. The number of protons it has. 3. The number of neutrons it has. 4. The combined number of protons and neutrons it has
Answer:
2. The number of protons it has
Explanation:
1. The number of electrons
This is incorrect because atoms and ions can have the same number of electrons from electron gain or loss
2. The number of protons it has
All atoms of an element have the same number of protons and every element has a different number of protons in its atoms. This is the correct option.
3. The number of neutrons it has
Examples includes carbon-12, nitrogen-13 and oxygen-14. They all have the same number of neutrons. This option is wrong
4. The combined number of protons and neutrons it has
Isobars are atoms that have the same mass number (proton and neutron). Examples are S-40, Cl-40, Ar-40 etc This option is wrong

What part of the atom determines the identity of an atom?
Every element has a unique atomic number. The atomic number is equal to the number of protons within the nucleus of every atom of the element. There are actually no two elements with the same number of protons within their atoms, so this numbers helps to identify an element.
In summary, the one thing that can determine an atom's identity would be the number of protons.
Hope this helps!
The number of protons (atomic number), which determines the chemical characteristics of the atom (element type), determines the nucleus, which is made up of protons with a positive charge and neutrons without a charge. The number of protons determines the identity of an atom.
The "basic building blocks of matter" are described as atoms. It is the lowest component of matter that possesses chemical elemental characteristics. Atoms do not exist alone; rather, they combine to create ions and molecules, which then join together to form matter in huge quantities.
The atomic number (Z) of an atom is the number of protons in the nucleus. The identification of the atom is determined by the element's value, which is its distinguishing characteristic.

Ariana is drawing a representation of the Milky Way galaxy. She wants to make sure it is the correct shape, and that she correctly labels both the object at the galactic center and the area of the galaxy where the Sun is located. What should she draw?
A
She should draw a spiral galaxy. The center should be labeled “supermassive black hole.” The Sun should be placed on the Orion Spur, about midway between the center and edge of the galaxy.
B
She should draw an elliptical galaxy. The center should be labeled “supermassive black hole.” The Sun should be placed in the Large Magellanic Cloud, near the edge of the galaxy.
C
She should draw an elliptical galaxy. The center should labeled “neutron star.” The Sun should be placed in the Crab Nebula, about midway between the center and edge of the galaxy.
D
She should draw a spiral galaxy. The center should be labeled “neutron star.” The Sun should be placed on the Perseus Arm, near the center of the galaxy.
Answer: A
Explanation:
The answer is the first option: A
The Milky Way is a spiral galaxy with a black hole in the center named Sagittarius A. The sun is located with the other middle aged stars in the Milky Way galaxy, which means it is placed midway from the center or edge of the galaxy.
