The brake pad has a block of
material fastened to a metal
backing plate?

A)Steel
B) Wood
C)Friction
D)Oily

Answers

Answer 1

D)The brake pad has a  block of friction material fastened to a metal backing plate.

Explanation:

A brake pad backing plate is designed in such a manner that it resists rust and maintain the adhesive bond between the friction material and plate over its entire life. Also, a brake pad backing plate must maintain dimensional stability.The brake pad has to be constructed quite well since It is a crucial as well as  critical component in a brake system. A block of friction material meets all these characteristics and thus preferred as a material in brake pads.
Answer 2
It’s most definitely D.

How do nozzles aerosolize liquids?

Answers

Answer:do you mean noddles

Explanation:not sure how to answer this.

Hello!

Answer:
Nozzles aerosolize liquids by breaking them up into small droplets or particles this process involves several steps:

1.pressure: liquids are often pressurized before being sprayed through a nozzle. This pressure helps to overcome the liquid surface tension and forces it through the nozzle opening.

2.constriction: the nozzle has a small opening, which constrains the flow of liquid as pressurized liquids passes through the narrow opening, the flow rate increases, and the liquid gains Momentum.

3.shear forces: as a liquid flows through the nozzle and experiences shear forces, these forces cause the liquid break apart into smaller droplets or particles. The size of the droplets produced depends on factors such as the liquids viscosity and the nozzle’s design.

4.Atomization: the shear forces generated by the nozzle result in the atomization of the liquid that means that the liquid is broken down into tiny, droplets or particles creating a aerosol. These droplets or particles are smart enough to remain suspended air.

5.spray pattern: the shape and size of the nozzle opening determine the spray pattern, different nozzle, designs produce different spray patterns, such as a wide cone, narrow cone, or flat fan. The spray pattern affects the distribution and coverage of the aerosolize liquid.
