Complete question:
A casting with a mass of 500 kg rests on a surface with a slope of 20° to the horizontal. The coefficient of friction is 0.25.
Calculate;
(a) the component of the weight of the object perpendicular to the surface
(b) the component of the weight of the object parallel to the surface
Answer:
(a) the component of the weight of the object perpendicular to the surface is 4,604.5 N
(b) the component of the weight of the object parallel to the surface is 1,675.9 N
Explanation:
Given;
mass of the casting, m = 500 kg
angle of inclination of the casting, θ = 20⁰
the coefficient of friction, k = 0.25
(a) the component of the weight of the object perpendicular to the surface;
F⊥ = mgcosθ
F⊥ = 500 x 9.8 x cos20
F⊥ = 4,604.5 N
(b) the component of the weight of the object parallel to the surface
F|| = mgsinθ
F|| = 500 x 9.8 x sin(20)
F|| = 1,675.9 N

Performing initial physical assessment upon client entry task may not be delegated by the preoperative nurse to unlicensed assistive personnel
<h3>What is
physical assessment?</h3>
The nurse can get a thorough evaluation of the patient thanks to an organized physical examination. Information-gathering methods include observation/inspection, palpation, percussion, and auscultation. Using clinical discretion, one should choose how extensive of an evaluation is necessary. Primary assessment (Airway, Breathing, Circulation, and Disability) and Focused systems assessment are only a few examples of assessment information. The "Shift assessment" section below provides detailed information on each evaluation criterion.
Every patient is assessed at the beginning of every shift, and the results are used to create a plan of care. Additional evaluations or changes should be noted in the progress notes after the initial shift assessment has been recorded on the patient care plan. Use clinical discretion while making decisions.
