All of the aforementioned factors generally affect friction except: B. Humidity.

<h3>What is friction?</h3>

Friction can be defined as a force that resists the relative motion of two physical objects when there surfaces come in contact. Thus, it prevents two surface from easily sliding over or slipping across one another.

In Science, some of the factors that generally affect friction are:

  • Surface finish
  • Material
  • Temperature

In conclusion, all of the aforementioned factors generally affect friction except humidity.

Steam enters a heavily insulated throttling valve at 11 MPa, 600°C and exits at 5.5 MPa. Determine the final temperature of the
7nadin3 [17]

Answer: the final temperature of the steam 581.5 °C

Explanation:

Given that;

P₁ = 11 MPa

T₁ = 600°C

exit at; P₂= 5.5 MPa

Now from superheated steam table( p=11 MPa, T=600°C)

h₁ = 3615 kJ/kg  

h₁ = h₂ ( by throttling process and adiabatic isentholpic )

from saturated steam table at; ( h= 3615 kJ/kg, P= 5.5 MPa )

Temperature = 581.5 °C

Therefore the final temperature of the steam 581.5 °C

Vanyuwa [196]

Answer:

a. is correct.

Explanation:

During servicing you should examine each bearing carefully for chips, pits, and scratches, so Technician A is correct.

Discoloration of a bearingbis not acceptable wear, so Technician B is false.

Combine the answers: Only Technician A is correct therefore answer a. is the right answer.

What is the resolution limit for a projection type of photolithographic system if the incident wavelength is 365 nm (the i-line
Vadim26 [7]

Answer:

Depth of field  = 347.619 nm

Explanation:

wavelenght =  365nm

N.A =0.63

k1= 0.6

so we have that the resolution limit is:

R=k1*A

R=0.6*365

R=219 nm

and the Depth of field needed for the best resolution is:

DoF = Resolution / N.A.

DoF= R/N.A

DoF= 219/0.63

DoF= 347.619 nm

4. Calculate the square root of potato using the sqrt() function. Print out the value of potato again to verify that the value o
N76 [4]

Answer:

potato<-100

print(potato)

sqrt(potato)

potato<-potato*2

print(potato)

Explanation:

The complete question is as follows

Create a variable called potato whose value corresponds to the number of potatoes you’ve eaten in the last week. Or something equally ridiculous. Print out the value of potato.

Calculate the square root of potato using the sqrt() function. Print out the value of potato again to verify that the value of potato hasn’t changed.

Reassign the value of potato to potato * 2.

Print out the new value of potato to verify that it has changed

The question was answered using R programming language.

At line 1, I assumed that I ate 100 potatoes in the previous week.

So, potato = 100

At line 2, the value of potato is printed as 100.

At line 3, the square root of potato is calculated using sqrt function: Square for of 100 = 10

At line 4,the initial value of potato is doubled and stored in potato variable. 100 * 2 = 200

At line 5, the new value of potato is printed: 200.

If the atomic radius of copper is 0.128 nm, calculate the volume of its unit cell in cubic meters.
Alex_Xolod [135]

Answer:

Volume of face centered cubic cell=4.74531*10^{-29} m^3

Explanation:

Consider the face centered cubic cell:

1 atom at each corner of cube.

1 atom at center of each face.

Consider the one face (ABCD) as shown in attachment for calculation:

Length of the all sides of face centered cubic cell is L.

Volume of face centered cubic cell= L^3

Now Consider the figure shown in attachment:

According to Pythagoras theorem on ΔADC.

L^{2}+L^2=(4a)^2     (a is the atomic radius)

L=\frac{4a}{\sqrt{2}} (Put in the formula of Volume)

Volume of face centered cubic cell= L^3

Volume of face centered cubic cell= (\frac{4a}{\sqrt{2}})^3

Volume of face centered cubic cell= (\frac{4(0.128*10^{-9}}{\sqrt{2}})^3

Volume of face centered cubic cell=4.74531*10^{-29} m^3
