Answer:
Safety ethics
Explanation:
The role of health and safety practitioners in the workplace is often troublesome due to the conflict between their duties to employers and the ethical standards of their occupations. They agree that providing a secure work environment provides the basis for organizational success and credibility in operational and financial efficiency. These leaders are motivated by a profound sense of dedication to ethical values, including the integrity of the workforce, value of life, justice, and achievement of the common good.
Answer: speed is different from velocity and acceleration
Explanation:
Acceleration is rate of change of velocity per unit time and velocity is rate of change of displacement(shortest path between initial and final point) per unit time. but speed is Distance per unit time. The difference between speed and other two terms is that, speed is scalar i.e it has only magnitude, velocity and acceleration has both velocity as well as direction.
- a(acceleration) = dv/dt
- v(velocity) = ds/dt
- speed = distance/time
Answer:
a diameter of D₂ = 0.183 inches would be required
Explanation:
appyling pascal's law
P applied to the hydraulic jack = P required to lift the rock
F₁*A₁ = F₂*A₂
since A₁= π*D₁²/4 , A₂= π*D₂²/4
F₁*π*D₁²/4 = F₂* π*D₂²/4
F₁*D₁²=F₂*D₂²
D₂ = D₁ *√(F₁/F₂)
replacing values
D₂ = D₁ *√(F₁/F₂) = 6 in * √(120 lbf/(4000 lbm * 32.174 (lbf/lbm)) = 0.183 inches
