Answer:
They have no freedom to move
Explanation:
Particles can be solids, liquids and gases.
Solids are the substances in which the atoms are very close to each other. It is very difficult to separate the molecules. The atoms cannot move from one place to another. The inter molecular forces between them is very strong.
Hence, the correct option that describes the movement of atoms in a solid is (c) "They have no freedom to move".
When a flowerpot falls from a window sill 36.5 m
above the sidewalk, then the velocity of the flowerpot is 26.7 m/s.
From Newton's third equation of motion,
v^2 = u^2 + 2gh
where,
h is the height of the object or body from ground
u is the initial velocity of the body or object
v is the final velocity of the body or object
g is the acceleration due to gravity
Now, as we know that
Flowerpot is at rest. So, u = 0
g = 9.81m/s^2
h = 36.5m
By substituting all the values, we get
v^2 = 2 × 9.81 × 36.5
= 716.13
v = 26.7m/s
Thus, we concluded that when a flowerpot falls from a window sill 36.5 m
above the sidewalk, then the velocity of the flowerpot is 26.7 m/s.

Answer:
The answer to your question is Nonmetals
Explanation:
Nonmetals they are bad conductors of heat and electricity except graphite.
Metalloids they are less conductors of electricity than metals.
Noble gases they conduct electricity.
Halogens they are not metals and do not conduct electricity.
From this information, we conclude that Oxygen and Selenium are nonmetals.
Since the orange rolls off the table and is (falling) its potential energy turnes into kinetic energy.

Answer:
Substance A will release more heat.
Explanation:
Let suppose that both substances experiment an entirely sensible heat process and are incompressible and begin at the same temperature. Physically speaking, specific heat (
), measured in kilojoules per kilogram-degree Celsius, can be described by following expression:
(1)
Where:
- Released heat, measured in kilojoules.
- Sample mass, measured in kilograms.
, 
- Initial and final temperatures of the sample, measured in degrees Celsius.
If we know that 
, 
, 
and 
, then we have the following inequation:
Substance A will release more heat.
