Answer:
So electric field between the plates will be equal to 
Explanation:
We have given potential difference between accelerating plates = 24 KV = 24000 volt
Distance between the plates d = 1.5 cm = 0.015 m
We know that potential difference is given by V = Ed, here E is electric field and d is distance between plates
So 
E = 1600000 N/C = 
So electric field between plates will be equal to 
Answer:
Kinetic Energy = 0
Explanation:
No matter if energy is totally conserved during the fall or when it hits the ground, the kinetic energy of the silver sphere will be zero because the velocity component in
becomes zero, the over all energy becomes zero.
Answer:
a. A list of the names of each student present today. (microstate)
b. The number of students in attendance. (macrostate)
Explanation:
You can fins the answer to this question by comparing the situation of the problem with a system of molecules with discrete energy.
Without importance of which molecules have a specific energy, but rather, what is the total amount of energy, you can get for different configurations of energy the same amount of the total energy. If different configurations of the energies of the molecules give you the same total energy of the system, you say that the macrostate is the same. In the case of the classroom, it does not matter how are distributed the students in the class, the total number of students is always the same. The macrostate is the same for what ever organization of the students in the class.
If you would interested in the energy of each molecules, you will obtain different configurations. In the case of the classroom. The names of the student will define a microstate because in this case there are many configurations.
a. A list of the names of each student present today. (microstate)
b. The number of students in attendance. (macrostate)
By definition,
density = mass/volume
The mass is 82 g
The volume is 14 cm³
Therefore
density = (82 g)/(14 cm³) = 5.857 g/cm³
In SI units, density = 5857 kg/m³
Answer: 5.857 g/cm³
