Explanation:
Amphipathic molecules are the molecules that consists of both polar and non-polar parts.
For example, fats and oils are amphipathic molecules.
Amphipathic molecules have two different parts. One is water loving which is also known as hydrophilic side and other is water fearing which is also known as hydrophobic side.
Molecules that are amphipathic must contain both hydrophilic and hydrophobic regions or parts.
Answer:
The net force on the middle wire will be zero.
Explanation:
Given:
There are three vertical wires. The wires to the left and in the middle have a current flowing vertically up and the wire to the right has a current vertically down.
Consider the figure shown. Let's assume that the magnitude of current in each wire is
and each wire is situated at a distance
from each other.
The magnetic field on the middle wire due to the wire in left is directed perpendicularly inward to the screen, as shown in the diagram. The magnetic field on the middle wire due to the wire in the right is directed perpendicularly outward to the screen, as shown in the diagram.
The force on the wire in the middle due to the left one is given by

where
is the permeability of free space.
The direction of the force is towards the wire in the left, as shown in the figure.
The force on the wire in the middle due to the right one is given by

The direction of the force is towards the wire in the right, as shown in the figure.
As the magnitude of the forces are equal but the directions are opposite to each other, the net force on the middle wire will be zero.
Electrical voltage is the potential energy of an electrical supply stored in the form of an electrical charge. From the equation I = V/R, the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.Therefore, the voltage of the current increases as it passes through a resistor.
Answer:
The value is 
Explanation:
From the question we are told that
The force applied on the ice is 
The mass of the ice block is 
Generally for the ice block to move at constant speed , the force applied on it must be equal to the kinetic frictional force which is mathematically represented as

=> 
=> 
=>
