Answer:
The velocity with which the mass will hit the floor is
Explanation:
If the tension in the string is , for
we have
,
and for the mass
From these equations we solve for and get:
The kinematic equation
gives the final velocity of a particle, when its initial velocity was
, and has traveled a distance
while undergoing acceleration
.
In our case
(the initial velocity of the particles is zero)
which gives us
which is the velocity with which the mass will hit the floor.
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.
