Referring to the diagram above, predict what will happen when the switch is closed. Explain your answer.
alisha [4.7K]

Answer

The nail will become an electromagnet.

Explanation

When the switched is closed , a current will flow in the insulated wire. Then the current flows through the coil around the iron nail, it will induce am magnetic filed inside the nail.  The nail becomes a magnet because it is made of magnetic material.  As long as there is current flowing through the current, there nail will remain a magnet.

Nuclear reactions have many useful applications, but they also have harmful biological effects.
Katarina [22]

True

Explanation:

Nuclear reactions have many useful applications but they also have harmful biological effects. Nuclear reactions are that occurs in the nucleus of an atoms. They differ from chemical reactions which occurs using valence electrons.

Some uses of nuclear reactions:

  • They are used for cancer therapy
  • Radioactive tracers.
  • Production of energy
  • Radiometric dating

Some harmful effects:

  • Uncontrolled nuclear reactions can lead to nuclear wastes in the environment.
  • They are used in manufacturing nuclear weapons.
  • They cause destruction of living cells because they produce ionizing radiations.

What is the force of impact of a 100 kg diver who falls into a swimming pool and hits the surface of the water and comes to a st
Simora [160]

Answer:

F = 53153.36[N]

Explanation:

In order to solve this problem, we must first use the principle of conservation of energy which is transformed from potential energy to kinetic, in this way we can determine the velocity at which the person enters the water.

E_{pot}=E_{kin}\\m*g*h=\frac{1}{2}*m*v^{2}

where:

m = mass = 100 [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 9 [m]

v = velocity [m/s]

Now replacing we can determinate the velocity.

v^{2}=2*g*h\\v=\sqrt{2*g*h}\\v=\sqrt{2*9.81*9}\\v = 13.28[m/s]

Then we can calculate the momentum which can be calculated as the product of force by time, this momentum is also equal to the product of mass by velocity.

P=m*v\\and\\P =F*t\\F*t=m*v

Now replacing:

F = impact force [N]

t = time = 0.025 [s]

m = 100 [kg]

v = velocity = 13.28 [m/s]

F*0.025=100*13.28\\F=53153.36[N]

Nataly_w [17]

Answer:

1.21 or 1.2 acceleration

Explanation:

i think it is 50.0/41.0

which would equal 1.21(depending on if you round it)
