Fluorine is the sample which is shiny but does not conduct heat and electricity through it. The flow of electricity requires the flow of electrons or charged particles. Thus, the correct option is A.
What are conductors?
A conductor is a substance, chemical element, or a material which allows electricity and heat to flow through it. In a conductor, the electrical charge carriers which are usually electrons or positive and negative ions, move easily from one atom to another atom when a particular amount of voltage is applied.
Fluorine is a shiny element however it does not conduct heat and electricity through it. It is the most electronegative atom and is very reactive in nature. It only gains electrons and does not lose them. And because of this property of fluorine, it restricts the movement of electrons through it and fails to conduct electricity.
Therefore, the correct option is A.

when a 1.5Kg box falls from a 2m shelf. Take
g=10N/Kg.
Answer:
30J
Explanation:
Given parameters:
Mass of box = 1.5kg
Height = 2m
Acceleration due to gravity = 10N/kg
Unknown:
Change in gravitational potential energy = ?
Solution:
The change in gravitational potential energy is given as:
ΔGPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
ΔGPE = 1.5 x 10 x 2 = 30J
can you please explain hooks law?
Explanation:
Hooke's law is a law of physics that states that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance—that is, Fₛ = kx, where k is a constant factor characteristic of the spring, and x is small compared to the total possible deformation of the spring.
Think about the types of forces holding the atoms together in different chemicals. Are there any patterns that can be drawn from the data? Explain.
Hello. You did not enter the data to which this question refers, which makes it impossible for it to have an exact answer. However, I will try to help you in the best possible way.
The forces that hold the elements together are called intermolecular forces. They are formed by covalent bonds between the molecules and can be called: dipole-induced (occurs between nonpolar molecules that have a negative pole and a positive pole) and dipole-dipole (occurs between polar moileculas, except when hydrogen is present).

As altitude increases in the troposphere and stratosphere, the air temperature does what?
A. decreases in the troposphere and increases in the stratosphere.
B. Decreases in both places.
C. Increases in the troposphere and decreases in the stratosphere.
D. Increases in both places
Answer:
1
Explanation:
The correct answer is decreases in the troposphere and increases in the stratosphere.
How does altitude affect the troposphere?For this reason, the density of gases decreases as the distance from Earth's surface increases. Put another way, air pressure (i.e., density) decreases as altitude increases.
How can altitude affect the temperature of a place?The temperature of a place decreases with increasing altitude from the earth's surface.

Mr. White drops a bowling ball and a feather from the top of the Washington Monument.
a) Which will hit the ground first? Why?
b) If Mr. White were to repeat this experiment inside a vacuum chamber, which would hit the ground first? Why?
If you can provide some explanation I would greatly appreciate it! :)
Answer:
A) The bowling ball will hit the ground first. It is heavier, which has greater density, allowing it to reach the ground first.
B) Feather. If you want to be able to blow a bowling ball in a vaccum cleaner, it's almost impossible since it's very heavy. If it's a feather, it would be easier as it's light and the air inside it is able to force it down.
Note: I haven't learnt physics at all yet, this is just an attempt. I'm in 7th grade currently and I will probably be taking physics sometime in 9th grade.
A person’s blood type depends on the type of protein marker, called an , found on the cell membranes of the red blood cells.
A person’s blood type depends on the type of protein marker, called an Antigen, found on the cell membranes of the red blood cell.
What is antigen?A molecule known as an antigen is one that triggers the formation of an antibody and the immune system's response.
Large protein molecules known as antigens are found on the surface of pathogens like bacteria, fungi, viruses, and other foreign substances. When these dangerous substances enter the body, the body's immune system reacts by producing antibodies.
The ABO system distinguishes 4 major blood types:
Blood group O - has no antigens, but both anti-A and anti-B antibodies in the plasma. Blood group AB - has both A and B antigens, but no antibodies.Blood group A - has A antigens on the red blood cells with anti-B antibodies in the plasma.

Cyclist 1 pedals 40 kilometers east in 2 hours. Cyclist 2 pedals 10 kilometers west in half an hour. Based on this information, which statement about cyclists is correct?
Answer:
See Explanation
Explanation:
Given
Cyclist 1:
[tex]Distance = 40km[/tex]
[tex]Time = 2hr[/tex]
[tex]Direction = East[/tex]
Cyclist 2:
[tex]Distance = 10km[/tex]
[tex]Time = 0.5hr[/tex]
[tex]Direction = West[/tex]
The question requires options. Since none is given, I'll answer on a general term.
First, calculate the speed of both cyclists
[tex]Speed = \frac{Distance}{Time}[/tex]
Cyclist 1:
[tex]Distance = 40km[/tex]
[tex]Time = 2hr[/tex]
[tex]Speed = \frac{40km}{2hr}[/tex]
[tex]Speed = 20km/hr[/tex]
Cyclist 2:
[tex]Distance = 10km[/tex]
[tex]Time = 0.5hr[/tex]
[tex]Speed = \frac{10km}{0.5hr}[/tex]
[tex]Speed = 20km/hr[/tex]
The following can be deduced from above:
Both cyclists travel at the same speed of 20km/hrBoth cyclists travel in opposite directions
How is velocity different from speed? Based on distance and/or direction
Answer:
Speed is solved with time and distance but has no direction
Average velocity is solved with Δx/Δt and has a direction

Example of kinetic to potential ? And how the energy is changing forms???? Please help
Answer:
A ball when from moving to stoping
Explanation:
Kinetic = energy of motion
Potential = energy stored
When you roll a ball on the ground, it gains kinetic energy, but then the ball starts to slow down until it stops and it remains at rest which means it's at potential energy. It went from moving (kinetic) to stoping (potential)
