Answer:
initial and final temperatures of both the water and metal, mass of the metal, and mass of the water
Explanation:
Heat lost by the metal,
Heat gained by the water in the calorimeter,
For energy to be conserved in the system, the heat lost by the metal will equal the heat gain by the water in the calorimeter.
Where,
m is the mass of the metal
c is specific heat capacity of the metal
t₂ is the final temperature of the metal
t₁ is the initial temperature of the metal
is the mass of the water
is specific heat capacity of water
is the final temperature of water
is the initial temperature of water
From the question given, specific heat capacity of the water is known, the quantities to be measured are;
Initial and final temperatures of both the water and metal,
Mass of the metal, and mass of the water
Answer:
(i) , (ii)
, (iii)
Explanation:
(i) and
represent the points where particle has a velocity of zero and spring reach maximum deformation, Given the absence of non-conservative force and by the Principle of Energy Conservation, the position where particle is at maximum speed is average of both extreme positions:
(ii) Maximum accelerations is reached at and
.
(iii) Greatest net forces exerted on the particle are reached at and
.
