Answer is: Dispersants


Explanation:

Dispersants keep contaminants (e.g. soot) suspended in the oil to prevent them from coagulating. Anti-foam agents inhibit the production of air bubbles and foam in the oil which can cause a loss of lubrication, pitting, and corrosion where entrained air and combustion gases contact metal surfaces.

So that's why the answer is: Dispersants

Answer:

b. Dispersants

Explanation:

  Dispersants contribute in a very similar way to the dispersion of the various ingredients (also contributing to the homogenization of a compound), the lubrication of the molecular chains and, in general, the lubrication of all mixing ingredients, thus decreasing the temperature rise of the compound by reducing the heat developed by internal friction.

Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week,
quester [9]

Answer:

<em>Jamie earned (Total pay)  $500.</em>

<em></em>

Explanation:

We are given the following code:

<em>If (Rate >=10) OR (Hours <=40) Then </em>

<em>    TotalPay = Hours * Rate </em>

<em>Else </em>

<em>    TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5 </em>

<em>End If</em>

<em />

Let us understand the code line by line:

The first line contains an if statement with 2 conditions:

i.e. 1st condition:

The rate is greater than or equal to 10

2nd condition:

Number of hours are lesser than or equal to 40.

There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.

The next statement is:

TotalPay = Hours * Rate

It calculates the pay if any of the two conditions written earlier becomes true.

Next statement is else statement:

It will get executed given that the above if() statement becomes false.

Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:

i.e.

Hours = 50

Rate = 10

Now, let get to the code execution.

The first condition is true i.e. Rate >= 10 (because Rate is 10 here)

So, the following statement will be used to calculate the Total pay:

TotalPay = Hours * Rate

and else part will not be executed.

TotalPay = 50 * 10  =<em> $500  </em>

<em></em>

<em>Jamie earned (Total pay)  $500.</em>
