Answer 1

Answer:

It is example of electrostatic energy...

And statement is true...

hope it helps you ☺☺

Answer 2

Answer:

Passive transport does not require energy.

Explanation:

An object moving on a smooth floor without friction then the energy released will be equal to zero. Because, on a slippery floor, the object will move on its own without requiring energy.

In other words, the concept of friction is influenced by two surfaces of objects touching each other. Friction is a form of force that opposes the motion of an object. Friction is the accumulation of micro-interactions between two contacting surfaces.

The forces at work include the electrostatic forces on each surface. It used to be believed that a smooth surface would cause the frictional force (or to be precise, the coefficient of friction) to be smaller than a rough surface, but nowadays this is no longer the case.

The micro-construction (nano to be precise) on the surface of the object can cause a minimum, even if it is liquid it will not dry. The occurrence of frictional forces in objects of no value. Friction can be greater if the surface of an object is very rough.

This is also true if the surface of the object is very smooth. That is, the magnitude of the frictional force on an object is strongly influenced by the roughness of the object's frictional surface. The direction of friction is always the opposite.

So frictional force will prevent objects from moving. The formula for friction is always influenced by the direction of inclination of the object to move. This is because friction is a force directed against the motion of objects.

Examples of frictional forces that can be seen in everyday life, for example, is when someone pushes a table. If the table is displayed on a very rough surface, the friction will be greater. Meanwhile, if the surface is smooth or the table has wheels underneath, the friction force becomes smaller.
