A 75.00 gram sample of an unknown metal initially at 99.0 degrees Celcius is added to 50.00 grams of water initially at 10.79 de
jeyben [28]

Answer:

  c_{e1} = 0.331 J / g ° C

Explanation:

We have a calorimetry exercise where all the heat yielded by one of the components is absorbed by the other.

Heat ceded          Qh = m1 ce1 (T_{h} -T_{f})

Heat absorbed     Qc = m2 ce2 (T_{f} - T₀)

Body 1 is metal and body 2 is water .  Where m are the masses of the two bodies, ce their specific heat and T the temperatures

      Qh = Qc

      m₁ c_{e1} (T_{h}- T_{f}) = m₂  c_{e2} (T_{f} - T₀)

we clear the specific heat of the metal

      c_{e1} = m₂  c_{e2} (T_{f} - T₀) / (m₁ (T_{h}-T_{f}))

     c_{e1}= 50.00 4.184 (20.15 -10.79) / (75.00 (99.0-20.15))

      c_{e1} = 209.2 (9.36) / (75 78.85)

      c_{e1} = 1958.11 / 5913.75

     c_{e1} = 0.331 J / g ° C

Assuming the same current is running through two separate coils, why is it easier to thrust a magnet into a wire coil with one l
alexira [117]

it is easier to thrust a magnet into a wire coil with one loop than one with four loops Because with four loops it becomes more difficult to push the magnet in.

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

It is the type of field where the magnetic force is obtained. The magnetic force is obtained it is the field felt around a moving electric charge.

The quantity of turns or loops in a coil directly relates to the intensity of the magnetic field within the coil.

As a result, the magnetic field strength has increased fourfold when there are four loops instead of one, making it more difficult to push the magnet in.

A single-looped wire coil is simpler to insert a magnet into than one with four loops. because inserting the magnet gets more challenging when there are four loops.

To learn more about the magnetic field refer to the link;
