Answer:
0.9 N, east
Explanation:
charge, q = 1 mC = 0.001 C
Electric filed, E = 900 N/C due east
Force, F = q E
F = 0.001 x 900
F = 0.9 N
The direction of force is same as the direction of electric field as the charge is positive in nature. So, the direction of force is also east.
Answer:
0.91437 m
0.22859 m
Explanation:
g = Acceleration due to gravity = 9.81 m/s² = a
When the time intervals are equal, if four drops are falling then we have 3 time intervals.
So, the time interval is
For second drop time is given by
Distance from second drop
Distance from second drop is 0.91437 m
Distance from third drop
Distance from third drop is 0.22859 m

The changes in internal energy of the system <u>75.1 J.</u>
The internal energy of a thermodynamic system is the total energy contained in it. It is the energy required to create or prepare a system in a given internal state and includes contributions of potential energy and internal kinetic energy.
Calculation:
Internal energy = 162.4 j - work done
= 162.4 j - 87.3 j
=<u> 75.1 J</u>
<u />
Internal energy, in thermodynamics, is the property or state function that defines the energy of matter in the absence of capillary action or external electric, magnetic, or other fields.
Internal energy is the microscopic energy contained in the matter given by the random and disordered kinetic energy of the molecules. It also includes the potential energy between these molecules and the nuclear energy contained in the atoms of these molecules.
