You are walking on a beach and find a mystery piece of metal. You take it back to your lab and measure its mass to be 0.5 kg. In
1 answer:
D) Silver
Explanation:
Given parameters:
Mass of metal = 0.5kg
temperature change = 1K
Quantity of heat = 115J
Unknown;
Identity of the metal = ?
Solution:
We first find the specific heat of the unknown metal and compare with the table of specific heat of metals.
C =
C = = 230JKg⁻¹K⁻¹
Comparing this value with the table shows that the metal is silver.

The height, h to which the package of mass m bounces to depends on its initial velocity, v and the acceleration due to gravity, g and is given below:
Perfectly elastic collisions are collisions in which the momentum as well as the energy of the colliding bodies is conserved.
In perfectly elastic collisions, the sum of momentum before collision is equal to the momentum after collision.
Also, the sum of kinetic energy before collision is equal to the sum of kinetic energy after collision.
Since some of the Kinetic energy is converted to potential energy of the body;
Therefore, the height to which the package m bounces to depends on its initial velocity and the acceleration due to gravity.
