Water atoms move more easily than ice
Ice is in a fixed crystal structure, it obviously has a lower temperature than liquid water, the state does not determine the charge, and when water freezes the crystalline structure actually makes it less dense than liquid because atoms are evenly spaced apart.
Answer:
two separate forces
Explanation:
Electricity and magnetism are two separate forces. However, they come together in a field called electromagnetism. Both types of forces are linked; a moving magnet may push electric charges and trigger electric current. Objects which have both positive and negative charges are mutually repulsive to each other, and those with opposite charges are mutually attractive.
Answer:
They all travel at the same speed
Explanation: the speed of light — in a vacuum, but when they come into contact with matter, they slow down. ... Opaque objects transmit little or no visible light, translucent objects transmit some, and transparent objects transmit almost all, which is why we can see through them.
Answer:
Magnitude of kinetic force is the product of the normal force and the coefficient of kinetic friction.
Explanation:
The kinetic frictional force is the force which is experienced in the moving surfaces of bodies.The magnitude of the force is affected by the coefficient of kinetic friction between the material of two bodies in contact. Mathematically, it is expressed as;
Fk=μk*η
where;
- Fk=force of kinetic friction
- μk=coefficient of kinetic friction
- η=normal force
