Answer:
Density of the sample will be 13.4 kg/L
Explanation:
We have given volume of the sample
Mass of the sample
We have to find the density of the sample
Density of the sample is given by
So density of the sample will be 13.4 kg/L

b) Now for the transition from n = 5 to n = 6
To solve this problem we could apply the concepts given by the conservation of Energy.
During the launch given in terms of kinetic energy and reaching the maximum point of the object, the potential energy of the body is conserved. However, part of all this energy is lost due to the work done by the friction force due to friction with the air, therefore
The potential and kinetic energy are conserved and are the same PE = KE and this value is equivalent to 100J, therefore
The kinetic energy will ultimately be less than 100J, so the correct answer is C.
