When you rub an inflated balloon on your head and it makes your hair stand up, the force that makes the hair stand up is known as static electricity.
When the balloon is rubbed on the head, electrons from the hair atoms move into the balloon, thus making the balloon to be negatively charged and the hair positively charged due to loss of electrons.
Unlike charges attracts. Thus, when you try to pull the balloon away slowly, the positively charged hair and the negatively charged balloon will attract each other and this is usually what makes the hair stand up.

Speed = distance/time
10m/2s = 5m/s
The speed is 5 m/s
Answer:
CN^- is a strong field ligand
Explanation:
The complex, hexacyanoferrate II is an Fe^2+ specie. Fe^2+ is a d^6 specie. It may exist as high spin (paramagnetic) or low spin (diamagnetic) depending on the ligand. The energy of the d-orbitals become nondegenerate upon approach of a ligand. The extent of separation of the two orbitals and the energy between them is defined as the magnitude of crystal field splitting (∆o).
Ligands that cause a large crystal field splitting such as CN^- are called strong field ligands. They lead to the formation of diamagnetic species. Strong field ligands occur towards the end of the spectrochemical series of ligands.
Hence the complex, Fe(CN)6 4− is diamagnetic because the cyanide ion is a strong field ligand that causes the six d-electrons present to pair up in a low spin arrangement.
Answer:
The resulting molarity is 6M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
12 M x 0,5L = C2 x 1,0 L
C2= (12 M x 0,5 L)/1,0 L
<em>C2= 6 M</em>
Answer:velocity of molecules within a body
Explanation:
Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.
