An object is attached to a hanging unstretched ideal and massless spring and slowly lowered to its equilibrium position, a dista

nce of 6.4 cm below the starting point. If instead of having been lowered slowly the object was dropped from rest, how far then would it then stretch the spring at maximum elongation?

Answer:

        h = 12.8 cm

Explanation:

from the equation we are given the following:

distance = 6.4 cm

  • when the object is being lowered the weight is equal to the spring force

        weight = spring force

         mg = ky ... equation 1

  • potential energy to stretch a spring = work done by the spring

        mgh = 0.5 x k x h^{2} ....equation 2

  • substituting equation 1 into equation 2

                kyh =  0.5 x k x h^{2}

                y =  0.5 x h

                2y = h

  • where y = 6.4 , the maximum elonf=gation becomes

          h = 2 x 6.4 = 12.8 cm

lubasha [3.4K]

Answer:

Explanation:

Given

Distance between two wires d=10 cm

Current value i_1=2 A

i_2=5 A

(a)If current flows in opposite direction

When current Flows in opposite direction the two wires will repel each other

Force due to current carrying wire F=\frac{\mu _0i_1i_2}{2\pi r}

F_{12}=F_{21}=\frac{\mu _0\times 2\times 5}{2\times \pi \times 0.1}

F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}

F_{12}=2\times 10^{-5} N (Repulsive Force)

(b)If current is flowing in the same direction

When direction of current is same then force will be attractive in nature

F_{12}=F_{21}=\frac{\mu _0i_1i_2}{2\pi r}

F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}

F_{12}=2\times 10^{-5} N (attractive Force)

What occurs when salt is evenly mixed with water
zimovet [89]
The more you mix salt with water the more the salt will dissolve
The act of dissolving in chemistry describes a physical change such as change in shape or state. Its important to remember that physical change does not change the chemical state.
