5 10 points Sanzida conducted an experiment that required a wire carrying a current to be wrapped around a metal core. When she

placed th metal rod, she observed the magnet move toward the rod. Which conclusion can Sanzida draw from this experiment? O The current in the wire has created a gravitational field with its south pole at the top of the rod. The current in the wire has created a magnetic field with its south pole at the top of the rod. The current in the wire has created a magnetic field with its north pole at the top of the rod. The current in the wire has created a gravitational field with its north pole at the top of the rod.​

The current in the wire has created a magnetic field with its north pole at the top of the rod.  A magnetic field influences electric currents.

<h3>What is a magnetic field?</h3>

A magnetic field is a type of field that influences the position and direction of the electric current.

The magnetic field also refers to the one where magnetic forces act to shape an electrical current.

The only material and/or body capable of altering an electrical current in a magnetic field is the presence of another magnetic field.

Ann [662]

Moment of inertia of single particle rotating in circle is I1 = 1/2 (m*r^2)

The value of the moment of inertia when the person is on the edge of the merry-go-round is I2=1/3 (m*L^2)

Moment of Inertia refers to:

  • the quantity expressed by the body resisting angular acceleration.
  • It the sum of the product of the mass of every particle with its square of a distance from the axis of rotation.

The moment of inertia of single particle rotating in a circle I1 = 1/2 (m*r^2)

here We note that the,

In the formula, r being the distance from the point particle to the axis of rotation and m being the mass of disk.

The value of the moment of inertia when the person is on the edge of the merry-go-round is determined with parallel-axis theorem:

I(edge) = I (center of mass) + md^2

d be the distance from an axis through the object’s center of mass to a new axis.

I2(edge) = 1/3 (m*L^2)

Cuando una persona sube y baja una escalera, Cuanto vale su desplazamiento y cual es la medida de su trayectoria.
adoni [48]

Answer:

Primero, definimos el desplazamiento como la distancia entre la posición final y la posición inicial.

Así, si comenzamos abajo, luego subimos la escalera, y luego bajamos, la posición final y la posición inicial serán la misma

por lo que el desplazamiento es igual a cero.

La medida recorrida es el espacio total recorrido.

Es decir, si entre el principio y el final de la escalera hay una distancia D.

La persona que sube y baja, recorre esta distancia dos veces.

Entonces cuando una persona sube y baja la escalera, la medida de su trayectoria será 2*D.

Which statement below could be used as evidence to support the claim that using nuclear energy to produce electricity is better
Montano1993 [528]

Answer:

C

Explanation:

C would make the most sense because the problem with fossil fuels is the fact that it emits greenhouse gases that warm up the earth over a long period of time as the climate has changed because of it.

How have earthquake data been used to explore the size of convection currents in the mantle?
nadezda [96]
 <span>Vibration waves from earth quakes travel through the earth and have measurable speed. And the different temperatures and fluidity of the various regions of the mantle will change that speed and or reflect the vibration waves in different directions. With multiple vibration sensors around the world the time that it takes for vibrations to travel from one part of the world to another will tell you what is inside.</span>
