They are a variable that changes as a result of the changes in the manipulated variable
Answer:
164.87 J
Explanation:
From the question,
Work done (W) = mghcosθ........................ Equation 1
Where m = mass of the box, h = height, g = acceleration due to gravity, θ = angle to the vertical
Given: m = 25 kg, h = 2.6 meters, θ = 75°.
Constant: g = 9.8 m/s²
Substitute these value into equation 1
W = 25×9.8×2.6×cos75°
W = 164.87 J.
Answer:
40L
Explanation:
Data obtained from the question include:
V1 (initial volume) = 60L
P1 (initial pressure) = 40mmHg
V2 (final volume) =?
P2 (final pressure) = 60mmHg
Using P1V1 = P2V2, the final volume can be obtain as illustrated below:
P1V1 = P2V2
40 x 60 = 60 x V2
Divide both side by 60
V2 = (40 x 60)/60
V2 = 40L
Therefore, the final volume is 40L
