Answer:
The specific question is not stated, however the general idea is given in the attached picture. The electric field in each region can be found by Gauss’ Law.
at r < R:
Since the solid sphere is conducting, the total charge Q is distributed over the surface, and the electric field inside the sphere is zero.
E = 0.
at R < r < 2R:
The electric field can be found by Gauss’ Law as in the attachment. The green pencil shows this exact region.
at 2R < r:
The electric field can again be found by Gauss’ Law, the blue pencil shows the calculations for this region.
Explanation:
Gauss’ Law is straightforward when applied to spheres. The area of the sphere is , and the enclosed charge is given in the question as Q for the inner sphere, and 2Q for the whole system.
The metal whose specific heat capacity is close to the obtained value is aluminum.
<h3>What is specific heat capacity</h3>
The specific heat capacity of an object is the heat required to raise a unit mass of the substance by 1 kelvin.
where;
- c is the specific heat capacity
- Δθ is change in temperature
Let the mass of the water = 50 g
mass of the metal for this first trial = 50 g
The heat gained by the water is calculated as follows
Specific heat capacity of the metal for the first trial is calculated as follows;
Heat gained by water = Heat lost by metal
Specific heat capacity of the metal for the second trial;
mass of metal = 200 - mass of water = 150 g
Specific heat capacity of the metal for the third trial;
Specific heat capacity of the metal for the fourth trial;
Specific heat capacity of the metal for the fifth trial;
Average specific heat capacity
The metal whose specific heat capacity is close to the above value is aluminum.
