The Hydrophobic phospholipid "tails." Cell Membranes are composed of lines of hydrophilic (water loving) phospholipid heads that face outside the cell and inside the cell. On the inside of the membrane, however, are hydrophobic (water hating) phospholipid tails, which repel charged particles.
What else can I help you with?
When the vinyl is rubbed with wool the electrons transferred to the vinyl. what kind of charge is on the pith ball when the charged vinyl repels it?
When the vinyl is rubbed with wool, it gains electrons and becomes negatively charged. The pith ball, which is initially neutral, will have its electrons repelled by the negatively charged vinyl, causing the pith ball to become positively charged due to the lack of electrons. As a result, the negatively charged vinyl repels the positively charged pith ball.
What repels electric charge?
A negative charge will repel a negative charge.
How does the structure of phospholipids linear molecules with a polar end and a nonpolar end relate to their function in the cell membrane?
The linear structure of phospholipids allows them to form a bilayer in the cell membrane due to their amphipathic nature, with the polar head facing outward towards water and the nonpolar tails facing inward. This arrangement helps create a barrier that controls the movement of substances in and out of the cell, contributing to the selective permeability of the cell membrane.
What of the cell membrane repeals water?
The lipid bilayer of the cell membrane repels water due to its hydrophobic nature. The hydrophobic tails of the phospholipids face inward and prevent water molecules from passing through easily, creating a barrier. This property helps regulate the movement of molecules into and out of the cell.
How is paint given a positive charge when it leaves a spray nozzle?
Paint is given a positive charge when it leaves a spray nozzle through a process called electrostatic spray painting. In this process, the paint is positively charged by passing it through a high-voltage electrode in the nozzle, creating a positive charge that repels the positively charged paint particles, causing them to disperse evenly and adhere more effectively to the surface being painted. This leads to better coverage and less overspray.
What pairs of charged particles will result in a repelling force acting between the particles?
+ repels + , - repels - .
A positively charged ion will bond with?
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
What is a force that attracts or repels particles?
magnetic pole
What are the main ideas of e Rutherford gold foil experiment?
basically, Rutherford shot postively charged particles at a thin sheet of gold foil. most of the particles passed straight through, but some bounced off at sharp angles. This implies that most of the atom is empy space (which is why most of the particles go straight throught) , but there is a positively charged nucleus at the center (which repels the postively charged particles, so if a particle hits the nucleus, it bounces off )
Does a positive electric field repels a positive charged object?
Yes.
Does current flow through wires?
It will flow if there is a voltage. Basically, that implies there is an electric field that attracts or repels charged particles.It will flow if there is a voltage.

Basically, that implies there is an electric field that attracts or repels charged particles.
What prevents charged molecules from diffusing across the cell membrane?
This depends on the membrane. For example, the plasma membrane of a eukaryotic cell allows many ions to passively diffuse. However, the prevention of ions across a membrane indicates that the membrane in question is most likely non-polar, meaning that they are hydrophobic. Non-polar molecules do not like to mix with polar molecules like ions, therefore they repel one another and active diffusion must be used to transport ions across a non-polar membrane.

When the vinyl is rubbed with wool, it gains electrons and becomes negatively charged. The pith ball, which is initially neutral, will have its electrons repelled by the negatively charged vinyl, causing the pith ball to become positively charged due to the lack of electrons. As a result, the negatively charged vinyl repels the positively charged pith ball.
What are some ways in which an object can become charged?
Some ways in which an object can become charged are friction, contact and induction.
What is the force that repels particles with a similar charge or attracts particles of differing charges.?
The force that repels particles with a similar charge is electrostatic repulsion, which is the result of like charges repelling each other. The force that attracts particles of differing charges is electrostatic attraction, which is the result of opposite charges attracting each other.
How does the cell membrane repel water?
The cell membrane repels water due to its structure, which is made up of a double layer of phospholipid molecules. These molecules have hydrophobic (water-repelling) tails that face inward, creating a barrier that prevents water from easily passing through. Additionally, the presence of proteins and other molecules embedded in the membrane can also contribute to repelling water.
Why does a balloon repel running water?
A balloon repels running water due to the static charge it acquires when rubbed against hair or clothing. The balloon becomes negatively charged, which repels the negatively charged water molecules. This creates a force that pushes the water away from the balloon.
