Brownian motion cannot be detected in colloids. True or false?

Answers

Answer 1

Answer: Brownianmotion is the random movement of colloidal particles suspended in a fluid. It iscaused by random collisions of the molecules in the fluid medium. The particlesin the solution or colloids are in constant random movement. A colloid hasproperties boundary to a homogenous and heterogeneous mixture. However inBrownian movement, the larger the size of a particle, the lesser its motion andthe smaller the size of the particle, the higher is motion. Colloids in generalhave larger particle size and therefore it Brownian motion is sluggish. The statementis false.

While discussing the effects of loose wheel bearings: Technician A says that vibration may occur while driving. Technician B says that the bearing may make noise. Who is correct? a. Technician A b. Neither A nor B c. Technician B d. Both A and B

Answers

Answer:

Option "D" is the correct answer i.e. Both Technicians A & B

Explanation:

Dear,

Loose wheel bearings can be caused on any machine.

The Following can be the reasons :

the machine or motor is installed improperly
the rotor(rotating part) of machine is not balanced
the cover get deteriorated with time
Bad manufacturer

So, when the bearings will be loose then the following can happen:

It will produce vibration in machine which can be judged by a vibration pen eg. SKF vibration pen
The vibration will also result in noise. You can check by
The machine winding if it is motor will burn-out.
Bush needs to be installed if the bearing runs loose.

Therefore, "D" is right.

An increase in which quantity will result in an increase in momentum?

Answers

Momentum = (mass) x (velocity)

(Remember that momentum is a vector ... it has a direction.
Its direction is the same as the velocity.)

An increase in either mass or velocity will increase the momentum.

It's pretty hard to increase the mass of a moving object, so I think
the better answer is velocity .

Explanation:

A surgeon for example can imagine the size, length, width that need to use or cut in a body if he/she can figure out tridimentional models, in this way if is going to connect a heart pump can imagine how is going to be.

An engineer, can imagine how is going to be a new building. He can visualize where to put some electric plug depending the needs and the capacity of the building.

In this way all the projects that they have in their minds can put together the different parts by a drawing in their heads.
