Answer:
D). Eesha pays more than the minimum payment each month.
Explanation:
Eesha would be considered most creditworthy among the given persons as she not only pays on time but also repays more than the minimum amount assigned to pay each month. In order to test the creditworthiness of an individual, his ontime debt paying capability is tested at first followed by the past credit repayment history and the credit score. Except Eesha, all the given candidates have failed to make timely repayment of their debts and hence, they cannot be considered creditworthy.

A) O True
B) O False
The statement "Employees are not responsible for their own safety while at work" is false because Employees most certainly are responsible.
What is Occupational safety?A multidisciplinary discipline dealing with the safety, health, and welfare of individuals at work is known as occupational safety and health, often known as occupational health and safety, occupational health, or occupational safety.
An environment that is safe and healthy for workers may minimize injury and sickness expenses, lower levels of absenteeism, boost output and quality, and improve employee morale. In other words, safety benefits the business.

Which of the following hazards is shared by surface mining and sub-surface mining?
rabid bats

B I guess. since they both have potential to collapse
Answer: Hazardous chemicals
Explanation:
Calculate the magnitude of the velocity and the θ angular direction of the block and the bullet together when the 50 g bullet moves to sky at a speed of 600 m/s and hits a sliding 4 kg block with a speed of 12 m/s in a direction with 30o with respect to ground.
Answer:
Magnitude of the velocity = 16.82 m/s
Angular direction, θ = 52.41°
Explanation:
As given ,
mass of bullet, m₁= 50g = 0.05 kg
speed of bullet , u₁ = 600 m/s
mass of the block , m₂ = 4 kg
speed of the block before collision , u₂ = 12 m/s
direction , θ = 30°
Now,
Assume that the combined velocity of bullet and block after collision = v
and the direction = θ
Now, from the conservation of momentum in x - direction :
m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) vₓ
where v = final velocity after collision
u₁ = initial velocity of bullet before collision = 0
m₁ = mass of the bullet before collision = 0.05 kg
u₂ = velocity of block before collision = 12 cos(30° )
m₂ = mass of block before collision
m₁ + m₂ = combined mass of bullet and block after collision = 0.05 + 4
∴ we get
0.05 (0) + 4(12 cos(30° ) ) = ( 0.05 + 4 ) vₓ
⇒ 0 + 4(6√3) = 4.05 vₓ
⇒24√3 = 4.05 vₓ
⇒vₓ = 10.26 m/s
Now, from the conservation of momentum in y - direction :
m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) [tex]v_{y}[/tex]
where v = final velocity after collision
u₁= initial velocity of bullet before collision = 600
m₁ = mass of the bullet before collision = 0.05 kg
u₂ = velocity of block before collision = 12 sin(30° )
m₂= mass of block before collision
m₁+ m₂= combined mass of bullet and block after collision = 0.05 + 4
∴ we get
0.05 (600) + 4(12 sin(30° ) ) = ( 0.05 + 4 ) [tex]v_{y}[/tex]
⇒ 30 + 4(6) = 4.05 [tex]v_{y}[/tex]
⇒30 +24 = 4.05 [tex]v_{y}[/tex]
⇒54 = 4.05 [tex]v_{y}[/tex]
⇒[tex]v_{y}[/tex] = 13.33 m/s
Now, the magnitude of the velocity = √vₓ² + [tex]v_{y}[/tex]² = √(10.26)² + (13.33)²
= √105.26 + 177.68
= √282.95 = 16.82
The angular direction, θ = [tex]tan^{-1}[/tex]([tex]\frac{v_{y} }{v_{x} }[/tex]) = [tex]tan^{-1}[/tex]([tex]\frac{13.33}{10.26}[/tex]) = [tex]tan^{-1}[/tex](1.299) = 52.41°

What is Labor?The procedure by which the placenta and fetus depart the uterus is called labor. Vaginal delivery (via the birth canal) and cesarean delivery (surgery) are the two possible methods of delivery.
In order for the fetus to pass through the birth canal, the cervix must first open (dilate) and thin (efface) during a series of ongoing, progressive contractions of the uterus called labor.
The Fair Labor Standards Act (FLSA) specifies requirements for minimum wage, overtime compensation, recordkeeping, and youth employment that are applicable to workers in the private sector and in federal, state, and municipal governments.
Typically, two weeks before or after the anticipated birth date, labor begins. Nobody, however, is entirely sure what starts labor.

in multi-grade oil what is W means?
Answer:
winter viscosity grades
Explanation:
The “W”/winter viscosity grades describe the oil's viscosity under cold temperature engine starting conditions. There's a Low Temperature Cranking Viscosity which sets a viscosity requirement at various low temperatures to ensure that the oil isn't too thick so that the starter motor can't crank the engine over.

What are the main factors contributing to the generation of heat in resistance welding (ideally explain based on equation)
Answer:
Q=I^2Rt
Explanation:
The principle of resistance welding is the Joule heating law where the heat Q is generated depending on three basic factors as expressed in the following formula
Q=I^2Rt
I is the current passing through the metal combination
R is the resistance of the base metals and the contact interfaces
t is the duration/time of the current flow.

A square rod is 2 m long and 0.5 m by 0.5 m in cross section. It elongates by 0.5 mm when subject to a tensile load P. The normal longitudinal strain is most nearly:_____
Answer: the normal longitudinal strain is most nearly 2.5 x 10⁻⁴ mm/mm
Explanation:
Given the data in the question,
we know that;
Normal longitudinal strain = elongation / original length
so we substitute our values
Normal longitudinal strain = 0.5 mm / (2 m x 1000) mm
= 0.5 mm / 2000 mm
= 2.5 x 10⁻⁴ mm/mm
Therefore the normal longitudinal strain is most nearly 2.5 x 10⁻⁴ mm/mm
The tool life decreases from 0.8 min to 0.2 min due to the increase in cutting speed from 60 m/min to 120 m/min in a turning operation.
Compute is the value of the cutting speed at 0.4 min.
a-)Determine the spindle speed in rpm.
b-)Find the required power for the unit force.
c-)The friction between tool and workpiece varies 0.25-0.35 during the process.
d-)Calculate the rate of maximum force to minimum force.
Answer:
The value of the cutting speed = 84.85 m/min
a.)The value of the spindle speed = 270.08 rpm
b.)The value of the Power for the unit force = 1.414 W
c.)[tex]u_{max}[/tex] = 0.35, [tex]u_{min}[/tex] = 0.25
d.)The rate of maximum force to minimum force = 1.4
Explanation:
As given, T₁ = 0.8 min
T₂ = 0.2 min
V₁ = 60 m/min
V₂ = 120 m/min
Now, as we know that Taylor's tool life equation -
VTⁿ = k
where V = speed in m/min
T = time in min
n = Index
k = constant
Now,
V₁T₁ⁿ = V₂T₂ⁿ
⇒60 (0.8)ⁿ = 120(0.2)ⁿ
⇒ (0.8)ⁿ = 2(0.2)ⁿ
⇒ ([tex]\frac{0.8}{0.2}[/tex] )ⁿ = 2
⇒4ⁿ = 2
Taking log both side , we get
⇒n log(4) = log(2)
⇒n = [tex]\frac{log(2)}{log(4)}[/tex] = 0.5
Now,
As given , T = 0.4 min
We know,
VTⁿ = V₁T₁ⁿ
⇒V (0.4)ⁿ = 60(0.8)ⁿ
⇒V = 60([tex]\frac{0.8}{0.4}[/tex] )ⁿ
⇒V = 60(2)ⁿ
⇒V = 60([tex]2^{0.5}[/tex])
⇒V = 84.85 m/min
∴ The value of the cutting speed = 84.85 m/min
a.)
As we know ,
V = π×d×N
Let d = 100 mm = 0.1 m
⇒ 84.85 = π×0.1×N
⇒ N = [tex]\frac{84.85}{0.1\pi } = 270.08[/tex] rpm
∴ The value of the spindle speed = 270.08 rpm
b.)
As we know,
P = F×V
⇒P = 1×[tex]\frac{84.85}{60} = 1.414[/tex] W per unit force
∴ The value of the Power for the unit force = 1.414 W
c.)
As given - The friction between tool and workpiece varies 0.25-0.35 during the process.
⇒[tex]u_{max}[/tex] = 0.35
[tex]u_{min}[/tex] = 0.25
d.)
Rate of maximum force , [tex]F_{max}[/tex] = [tex]u_{max}[/tex] × Normal force
Rate of minimum force , [tex]F_{min}[/tex] = [tex]u_{min}[/tex] × Normal force
∴ we get
[tex]\frac{F_{max} }{F_{min} } = \frac{u_{max} }{u_{min} } = \frac{0.35}{0.25}[/tex] = 1.4
∴ we get
The rate of maximum force to minimum force = 1.4
