Define
x = the manipulated variable
y = the responding variable.

Because an inverse relationship exists between y and x, therefore
y = k/x
where
k =  constant.

A graph of y versus x will be a curve that has a vertical asymptote at x = 0, and a horizontal asymptote at y = 0, as shown below.

Answer: B. a curved line

Viktor [21]

Answer:

B. for an object that floats

Explanation:

For an object to float the weight of the object must be balanced by the buoyancy force.

However an object will sink if the  magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same volume as the object.

igor_vitrenko [27]

Answer:

                  = 5.241 \times 10^{-5} m

Explanation:

Given:

 Length of cylinder is, L = 0.27 m

Outer radius of cylinder is, r_out = 1.12×10^{-2} m

Inner radius of cylinder is, r_in = 3.9×10^{-3} m

Mass of person, m = 60 kg

 Young's modulus , Y = 9.4×10^9 N/m2

(a)

     Compressional strain of humerous is,

Strain = \frac{Stress}{Young's\ modulus}

     \frac{\Delta L}{L_0}   = \frac{\frac{F}{A}}{Y}

                  = \frac{(mg)}{\pi(r_out^2 - r_in^2  )Y}

                  = \frac{(60 kg)(9.8 m/s2 )}{(\pi)[( 1.12\times 10^{-2})^2 - (3.9\times 10^{-3} m)^2] (9.4\times 10^9 N/m2 )}[tex]                   [tex]= 1.80\times 10^{-4} m

(b)  Let assume that humerous is compressed by ΔL

       Since,   strain = ΔL/L0

      (1.80 \times 10^{-4} m) = ΔL / 0.29 m

     Thus,

           ΔL = (4.56 \times 10^{-4} m)(0.29 m)

                  = 5.241 \times 10^{-5} m

Alecsey [184]

Answer:

It takes 0.43 seconds before the pendulum attains the maxium speed.

Explanation:

L= 0.75m

g= 9.8 m/s²

T= 2π * √(L/g)

T=1.73 sec

T(vmax) = T/4

T(vmax) = 0.43 sec
