Answer: The correct statements are:
- The atoms are very attracted to one another.
- The atoms are held tightly together.
Explanation:
Solid state: In this state, the molecules are closely packed and cannot move freely from one place to another that means no space between them and the intermolecular force of attraction between the molecules are strong.
In solid substance, the particles are very close to each other due to this the intermolecular forces of attraction are strongest.
The key point about solid are:
- The atoms are very attracted to one another.
- The atoms are not moving freely.
- It will not spread out evenly to fill any container.
- The atoms are held tightly together.
- The forces of attraction are strong to bring molecules together.
- The atoms are close and in fixed positions.
Answer:
Masses and distance between them
Explanation:
The gravitational force between two objects can be calculated using Newton's Gravitational Law.
However, using logic, we can already dictate what the answer will be, for example. We know that the bigger an object is, the stronger its gravity is. This can be seen with how the moon is much smaller, and also has much less gravity.
Also, the distance between two objects also influences the gravity. This can be seen the further an object gets from Earth, the less of a pull the gravitational field has on it. Another example is that Pluto (being very far from the sun) has less of a gravitational effect from the sun, in comparison to Mercury (the closest plant to the sun).
Answer:
The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.
The orbital diagram of an orbit containing 16 electrons will be as follows:
1s²2s²2p⁶3s²3p⁴
- The maximum number of electrons in each sublevel of the orbitals are:
- 2 electrons for s-sublevel with one orbital
- 6 electrons for p-sublevel with three orbital
- 10 electrons for d-sublevel with five orbital
- 14 electrons for f-sublevel with seven orbital
Answer:
1) 50°
Explanation:
We need to find the angle of incidence first before finding the angle of reflection.
Angle of incidence = 90° - 40°
= 50°
Since the angle of incidence is the same as the angle of reflection, the angle of reflection here would be 50°.
The brainstem is the innermost region of the brain. Considered to be the "trunk" of the brain, the brainstem is the posterior region of the brain composed of three main parts: medulla oblongata, pons, and midbrain. It is a continuous structure connected to the spinal cord.
