A) When the angle between the Force (F) and Displacement (x) is 0°, because, Work done (W) is directly proportional to the Cosine of the Angle between the Force applied and the resultant displacement of the subject. W = F•x cos ∅ If ∅ = 0°, W = F•x ===> Maximum Work Done. If ∅ = 45°, W = F•x/√2 If ∅ = 90°, W = 0 If ∅ = 180°, W = –F•x ===> Minimum Work Done.
The force of friction is given by: f = μR, where μ is the friction coefficient and R is the reaction force, which will be equal to the weight. 100 = μ x 130 μ = 0.77
<span>Joy is planning to purchase a sweater that costs $30 dollars at her local department store. The sweaters are on sale for 20% off. Which steps are needed to find the sale price of the sweater?</span>
