Answer: The amount of movement of the particles depends on the amount of <u>force</u> acting on them and their relationship to other atoms.
Explanation:
The inter-atomic force determines the inter-atomic distance which governs the amount of movement of the particles.
For example in solids, the inter-atomic force is stronger and hence, the distance between any atoms is very very small which restricts the movement of the particles. On the other hand, in case of liquids and gases, the inter-atomic forces are not very strong and there is more distance between the atoms which allows free movement of particles.
Answer:
a toy car was on the floor in the play room until the child applied force by starting to race with it. it accelerated and proceeded to move at 5m/s east. it came to a stop when the bedpost applied force to it.
Answer:
N≡N bond
Explanation:
Bond energy (bond enthalpy) is a measure of the bond strength in the bond. It is defined as average value of bond dissociation energies in the gas-phase for all the bonds having same type with in same chemical species.
<u>The greater the bond energy, the greater is the amount of energy required to break the bond, the more stable is the bond.</u>
Thus, among the following bonds:
O=O 498 kJ/mol
N≡N 946 kJ/mol
C=C 614 kJ/mol
C=O 745 kJ/mol
C≡C 839 kJ/mol
<u>The greatest bond energy is of N≡N 946 kJ/mol and thats why it is the most stable.</u>
I think the correct answer from the choices listed above is the second option. An impact of a thermoelectric power plant on the environment would be it <span>uses a lot of water which will significantly decrease the supply and amount of water available for use. Hope this answers the question. Have a nice day. </span>
Answer
3.340J
Explanation;
Using the relation. Energy stored in capacitor = U = 7.72 J
U =(1/2)CV^2
C =(eo)A/d
C*d=(eo)A=constant
C2d2=C1d1
C2=C1d1/d2
The separation between the plates is 3.30mm . The separation is decreased to 1.45 mm.
Initial separation between the plates =d1= 3.30mm .
Final separation = d2 = 1.45 mm
(A) if the capacitor was disconnected from the potential source before the separation of the plates was changed, charge 'q' remains same
Energy=U =(1/2)q^2/C
U2C2 = U1C1
U2 =U1C1 /C2
U2 =U1d2/d1
Final energy = Uf = initial energy *d2/d1
Final energy = Uf =7.72*1.45/3.30
(A) Final energy = Uf = 3.340J
