Answer:

Explanation:
Let establish a control volume in the industrial pressure cooker, which is a transient state system. From the First Law of Thermodynamics, the heating process is modelled:

The heat transfered to the cooker is:

Properties at each state are described below:
State 1


State 2


The heat transfered to the cooker is:


The <span>first law of thermodynamics</span><span> is a version of the law of </span>conservation of energy<span>, adapted for </span>thermodynamic systems<span>. The law of conservation of energy states that the total </span>energy<span> of an </span>isolated system<span> is constant; energy can be transformed from one form to another, but cannot be created or destroyed. so assuming no heat losses then heat removed is also 333 J</span>
Answer:
(a). The time is 26.67 sec.
(b). The distance traveled during this period is 1066.9 m.
Explanation:
Given that,
Speed = 80 m/s
Acceleration = 3 m/s
Initial velocity = 0
(a). We need to calculate the time
Using equation of motion


Put the value into the formula


The time is 26.67 sec.
(b). We need to calculate the distance traveled during this period
Using equation of motion



The distance traveled during this period is 1066.9 m.
Hence, This is the required solution.
Answer:
The concentration of acetic acid present in the vinegar is 0.113M
Explanation:
1. As the titration occurs between an acid and a base is called neutralization. The balanced chemical reaction between the acetic acid and the NaOH is:

2. Calculate the moles of NaOH used, taking in account the concentration of NaOH 1.00M:

3. Calculate the number of moles of acetic acid neutralized using stoichiometry:

4. Calculate the concentration of acetic acid present in the vinegar:

Answer:
Magnitude of the resultant force will be 20N in the direction of
.
Explanation:
It's given in the question that two forces have been applied on the object given.
Since force is a vector quantity, therefore, it has magnitude and direction both.


Both the forces are in the opposite directions.
Therefore, magnitude of the resultant force of these forces will be,

= 20 N
And the direction of the resultant force will be towards
.
Therefore, magnitude of the resultant force will be 20N in the direction of
.
