Final Answer:
To determine if the strength of the electric field decreases as 1 over distance squared (1/r²), we need to measure the electric field at 0.5 m and 1 m directly above the midpoint of a small dipole created by two charges brought very close together.
Explanation:
In this experiment, you're examining the electric field generated by a small dipole. The electric field strength at a distance from a dipole does follow an inverse square law, as suggested by 1/r², which is a fundamental principle of electrostatics. This means that the electric field's strength decreases as you move farther away from the charges.
To verify this, you'll measure the electric field at two different distances (0.5 m and 1 m) directly above the midpoint of the dipole. By comparing these measurements, you can assess whether the field strength obeys the 1/r² relationship. The electric field strength should be four times stronger at 0.5 m than at 1 m if it follows the 1/r² law.
This experiment provides hands-on insight into the behavior of electric fields and their relationship to distance, supporting the foundational principles of electrostatics.

B. Electric forces and gravitational forces are equal in this setting.
C. Electric forces are much stronger than gravitational forces.
Answer:The correct answer is option C.
Explanation:
Electrical forces are forces between the charge particles of different charges or of same charges.This type of force is termed as electrostatics forces.
Like charges repel each other and unlike charges attract.They are dipole forces and stronger than the gravitational forces which only attracts and are monopole forces.
Atom consist of protons and electrons with positive and negative charge respectively.The force between these subatomic particles are very stronger than the gravitational forces between these particles.This is due to very smaller masses of protons and electrons the gravitational force between them is very small.
the correct answer is C hope this helps a little
O Diffusion requires energy only to move material in through the cell membrane.
O Diffusion does not require energy in any situation.
O Diffusion requires energy only to move material out through the cell membrane.
The statement that the energy involved in diffusion is as follows:
Thus, the correct option is C.
Diffusion may be defined as the process of migration of substances or molecules through a semipermeable membrane from an area of higher concentration to an area of lower concentration.
Diffusion does not require energy because it is classified under the passive transport of materials. Diffusion always works towards the concentration gradient.
Energy is typically involved when the movement occurs against the concentration gradient like active transport.
Therefore, the correct option for this question is C.

Explanation: The turnoff point for a star refers to the point on the Hertzsprung–Russell diagram where it leaves the main sequence after its main fuel is exhausted-the main sequence turnoff. HR diagrams for two open clusters, M67 and NGC 188, showing the main sequence turn-off at different ages.
B. Climate Change
C. Volcanic Eruption
Answer:
B. climate change
Explanation:
asteroids are too big and volaconos are probably gonna create a lot of smoke that can kill ya in seconds so I guess climate change
