The best conclusion that can be drawn is that D) A current does not flow in the wire

Answer: The correct answer is (D).

Explanation:

If the current is flowing in the wire then the compass shows the deflection due to the magnetic field around the current flowing wire.

In the given problem, four compasses are placed around a wire, as shown in the given figure. The compass is not showing any deflection. It means that there is no magnetic field around the wire. It can be concluded that the current is not flowing in the wire.

Therefore, the correct option is "A current does not flow in the wire".

3. An object of mass 90 kg travels down a slide.
Gwar [14]

Answer:

3) Ep = 13243.5[J]

4) v = 17.15 [m/s]

Explanation:

3) In order to solve this problem, we must use the principle of energy conservation. That is, the energy will be transformed from potential energy to kinetic energy. We can calculate the potential energy with the mass and height data, as shown below.

m = mass = 90 [kg]

h = elevation = 15 [m]

Potential energy is defined as the product of mass by gravity by height.

E_{p}=m*g*h\\E_{p}=90*9.81*15\\E_{p}=13243.5[J]

This energy will be transformed into kinetic energy.

Ek = 13243.5 [J]

4) The velocity can be determined by defining the kinetic energy, as shown below.

E_{k}=\frac{1}{2} *m*v^{2}  \\v = \sqrt{\frac{2*E_{k} }{m} }\\ v= \sqrt{\frac{2*13243.5 }{90} }\\v=17.15[m/s]

Which of the following ranching practices contributes to soil erosion?
Natasha2012 [34]

A. overgrazing of livestock

Explanation:

Overgrazing of livestock is the ranch practice that contributes to soil erosion.

Soil erosion is the washing away of the top layer of the earth on which plant grows.

  • Plants are covers of the earth and they prevent agents of denudation from actively washing away the soil.
  • When livestock are introduced into a place, continuous grazing leaves the surface bare.
  • The plants becomes depleted and the surface is exposed.
  • This fast tracks the process of overgrazing.
