Explain some methods of reducing friction between of matyer​
Simora [160]

Answer:

Step-by-step explanation:

1. Use of lubricants

Lubricants like oil and grease helps to decrease friction by forming a thin film in between different parts of the machine. This film covers up the scratches and bumps on the surfaces of different parts. This reduces interlocking between the two surfaces.  Thus reducing the friction.

2. Use ball bearings

Two moving surfaces in a machine are attached by placing small steel balls or steel rollers  in between them. This way, the moving parts avoid direct contact and the force of sliding friction turns into rolling friction. Rolling friction is less than sliding friction, in doing so reducing the friction.

3. Polishing

Polishing reduces the unevenness  of a surface. This will reduce interlocking between the surfaces.  

4. Streamlining

Streamlining is the process where you make a machine in a shape that avoids air and water resistance. This reduces friction because a streamlined object cuts through the water and air molecules.

Which binomial is a factor of 100x2 – 49?
pentagon [3]

Answer:

Step-by-step explanation:

What you have here is called "the difference of two squares"

Difference means subtraction and both 100x2 and 49 are perfect squares.

The factored form of 100x2-49 is

(10x+7)(10x-7)

Because 10x times 10x is 100x2 and 7 times 7 is 49

One factor has a + and

One factor has a -

It is a pattern worth memorizing!

So 10x + 7 is the factor you're looking for.
