A student has a thin copper beaker containing 100 g of a pure metal in the solid state. The metal is at 215°C, its exact melting

temperature. If the student lights a Bunsen burner and holds it for a fraction of a second under the beaker, what will happen to the metal?

Answer:

The metal will melt but their will be no change in temperature.

Explanation:

The metal is at its melting temperature which means it is still in solid phase but have to cross the enthalpy of its condensation at this same temperature to convert into liquid phase.

<u>On supplying heat, the metal's temperature will not change as the heat will be required as enthalpy of condensation to melt the solid to liquid at the melting temperature.</u>

What is a magnetic field’s shape?
Agata [3.3K]

Answer:

Magnets come in a variety of shapes and one of the more common is the horseshoe (U) magnet. The horseshoe magnet has north and south poles just like a bar magnet but the magnet is curved so the poles lie in the same plane. The magnetic lines of force flow from pole to pole just like in the bar magnet.

A 108 kg clock initially at rest on a horizontal floor requires a 653 N horizontal force to set it in motion. After the clock is
kifflom [539]

Answer:

\mu_s=0.61

\mu_k=0.49

Explanation:

Given that,

Mass of the clock, m = 108 kg

When the clock is not moving, force acting on it, F_1=653\ N

For the clock in motion, force acting on it, F_2=527\ N

To find,

\mu_s\ and\ \mu_k

Solution,

When an object is at rest, the force acting on it is called force due to static friction and if the object is in motion, the force acting on its called force due to kinetic friction.

Let \mu_s is the coefficient of static friction. Force is given by :

F_s=\mu_smg

\mu_s=\dfrac{F_s}{mg}

\mu_s=\dfrac{653}{108\times 9.8}

\mu_s=0.61

Let  \mu_k is the coefficient of kinetic friction. Force is given by :

F_k=\mu_kmg

\mu_k=\dfrac{F_k}{mg}

\mu_k=\dfrac{527}{108\times 9.8}

\mu_k=0.49
