Explanation: Copper is a non-ferrous product (like aluminuim for example), and also the just materials impacted by a magnet (or a magnetic field) space the ferrous ones, for this reason the correct wgc2010.org will certainly be the option B, the copper will certainly be unaffected by the magnet.

You are watching: If a bar of copper is brought near a magnet, the copper bar will be



It will be unaffected through the magnet due to the fact that it has actually no magnetic field. If you to be to possibly have electrical power going with it is the only means it would have anything to perform with the magnet. 


What residential or commercial property of two objects determines if the two are in a state of thermal equilibrium?If 2 objects have the same temperatur

Explanation:

Thermal equilibrium is the state in which there is no net flow of thermal energy between two body in contact. This wake up when, ~ a specific time, the temperature the both body is the same. Since both temperatures room the same, the heat flow is zero.



The exactly wgc2010.org come the inquiry is: C) They manage the rate of reaction.

EXPLANATION:

The manage rod plays a critical role in nuclear reaction. The main role of the control rod is to manage the rate of reaction.

The atom chain reaction becomes uncontrolled when variety of neutrons room not controlled. That is so due to the fact that each degeneration of radiation uranium or plutonium produces three extra neutron which again decay the radioactive sample in ~ a quicker rate.

The regulate rods are consisted of of boron,indium and cadmium choose substances. Castle absorb the thermal neutrons created in each degeneration of radioactive specimen. In this way, they control the rate of reaction.

A 20.0kg- projectile is fired in ~ an angle of 60.0 above the horizontal through a rate of 80.0 m/s. In ~ the highest allude of the tra
Katen <24>

wgc2010.org:

The activity of the projectile can be break-up up in two motions, the horizontal and also the vertical motion. The vertical velocity v for a time t, acceleration g and also initial velocity is offered by:

(1)

*

At the highest point of flight the velocity will certainly be zero and equation 1 have the right to be solved for time t:

(2)

*

The velocity that the projectile in the horizontal direction as much as the highest suggest is constant:

(3)

*

At the highest allude of trip the projectile explodes. All forces are internal, so momentum should be conserved.

The inert p prior to the explosion:

(4)

*

The momentum after the explode with fifty percent the projectile having actually zero velocity:

(5)

*

The velocity of the rest of the projectile after ~ the explosion can be discovered from equations 3, 4 and also 5:

(6)

*

The total distance that the projectile fragment have the right to now it is in calculated:

(7)

*

*

The explosion releases kinetic energy. The kinetic power of the projectile prior to the explosion:

The kinetic energy after the explosion:

(9)

*

The power released:
