A rod (length = 2.0 m) is uniformly charged and has a total charge of 5.0 nC. What is the electric potential (relative to zero a
Ksenya-84 [330]

Answer:

The electric potential is  V  =  15.6 V

Explanation:

From the question we are told that

   The length  of the rod is  L =  2.0 \ m

     The total charge of the rod is  q =5.0 nC = 5.0*10^{-9} C

      The length from the center is  d =  3.0 \ m

The diagram illustrating the setup for this question is shown on the first uploaded image

From the diagram the potential at point  A  dl is mathematically represented as

         dV  =  K  \frac{dq}{l}

Where K is the coulomb constant with a value  K  = 9*10^9 \   Nm^2 /C^2

where q is the charge in charge  the rod relative to its distance from A  is mathematically represented as

         dq =  \frac{q}{L}  dl

This a small unit length of the rod

So         V = \frac{q}{L}  \int\limits^4_2  {\frac{dl}{l} } \,

        =>   V =  k\frac{q}{L}  ln [\frac{4}{2} ]

              V =  k\frac{q}{L}  ln2

Substituting values

                V  =  9* 10^9  *  \frac{5*10^{-9}}{2} * ln 2

                 V  =  15.6 V

Plants may get yellow if they get less nitrogen.give reasons.​
Vaselesa [24]

Explanation:

Nutrient deficiency causes yellowing of leaves. One of such nutrient is Nitrogen.

  • Leaves are green because of a pigment in them called chlorophyll.
  • The chlorophyll in leaves are used by plant to absorb light energy needed for photosynthesis.
  • Other wavelength of light is absorbed by the chlorophyll and the green color is reflected.
  • Nitrogen is an important nutrient that is needed to produce chlorophyll in plants which in turn helps the process of photosynthesis.

While carrying a heavy box up the stairs,you set the box on a step and rest. Then you pick up the box and carry it to the top of
slega [8]

Answer: When the box is on a step and in a resting position then in this situation, the forces acting on the box is said to be balanced forces. While carrying the box to the top of the stair then the forces acting on it will be unbalanced forces.

Explanation:

When the box is on a step and in a resting position then the forces acting on the box are acting in an equal in magnitude and opposite in direction. Therefore, these forces are balanced forces.

While carrying the box to the top of the stair then the forces acting on it will be unbalanced forces because the box is changing its state. There is an unbalanced force which opposes the motion of the box.
