Respiratory protection <u>provides fool proof protection</u> against fumes and gases during wielding.
<h3>What is PPE?</h3>
PPE is an acronym for personal protective equipment and it can be defined as a terminology that is used to denote any piece of equipment which is designed and developed to offer protection to different parts of the body while working in a potentially hazardous environment.
Some examples of personal protective equipment (PPE) that are used to protect the different parts of the body include the following:
- Respirators
- Face mask
- Face shield
- Gloves
- Boots
- Helmet
In conclusion, respiratory protection <u>provides fool proof protection</u> against fumes and gases during wielding.

Explanation:
You can use Hollomon's equation to estimate this.
Y_f is the flow stress.
K is the strenght coefficient or constant.
e is the strain
n is the strain hardening exponent.
You should be able to solve for e given the data in the problem statement.
<h3><u>The velocity of the car after 10 s is 78.95 km/hr</u></h3>
Explanation:
<h2>Given:</h2>
m = 1,250 kg
= 30 km/hr
F = 1,700 N
t = 10 s
<h2>Required:</h2>
Final velocity
<h2>Equation:</h2><h3>Force</h3>
F = ma
where: F - force
m - mass
a - acceleration
<h3>Acceleration</h3>
a = 
where: a - acceleration
- initial velocity
- final velocity
t - time elapsed
<h2>Solution:</h2><h3>Solve for acceleration using the formula for force</h3>
F = ma
Substitute the value of F and m
(1700 N) = (1250 kg)(a)
a = 
a = 1.36 m/s²
<h3>Solve for final velocity using the formula for acceleration</h3>
= 
= 
- Substitute the value of a, and t
a =
= 
= 
<h2>Final answer</h2><h3><u>The velocity of the car after 10 s is 78.95 km/hr</u></h3>
Answer:
somewhere around 34.2223 meters thick but that's what I am estimating.
