Preeti Dabral 3 years, 1 month ago

A fuse that has a lower rating would result in a problem as one may need to frequently change it. A fuse that has a higher rating would not melt at higher currents too . this may lead to damage to the appliance. Therefore, the fuse should be replaced with that of an identical rating.

5 answers

Madhu Singh 3 years, 1 month ago

If the original length and the cross-sectional area of the wire are landA, respectively, then R=ρlA or 20Ω=ρlA. When the length becomes 2l and cross-sectional area is A/2. Rnew=ρ(2l)A/2=4(ρl/A)=4(20Ω)=80Ω

Regeneration in multicellular organism like Hydra

It is carried out by specialised cells.
When Hydra is cut or broken up into many piecs these specialised cells proliferate and make large number of cells.
From the mass of cells, differentiation occurs developing various cell types and tissues.
These changes take place in an organised sequence which lead to development of new individual

Why does Micelle Formation take place when soap is added to water? Will or Micelle be formed in Other solvents such as ethanol aldi?

Posted by Padam Jain 3 years, 1 month ago

CBSE > Class 10 > Science

1 answers

Preeti Dabral 3 years, 1 month ago

Soaps are sodium or potassium salts of long chain fatty acids. The action of a soap is based on the presence of both hydrophilic and hydrophobic groups in a soap molecule. This action emulsifies the oily dirt and helps in its removal.
The two ends of a soap molecule have different properties. When soap is added to water, the ionic, hydrophilic end of soap molecule dissolves in water. The hydrocarbon chain of soap molecule is hydrophobic and it dissolves in hydrocarbons i.e. links with oily dirt. The hydrocarbon chain of soap molecule orients towards the oil droplet while the ionic end orients towards water (polar solvent). This is how, soap molecules form structures called micelles where the oily dirt is collected in the centre. Thus, soap micelles help in dissolving dirt in water. Micelles stay in solution as colloids and the dirt suspended in the micelles is easily rinsed away.
Micelle formation will not take place in a solvent like ethanol because ethanol will dissolve the hydrocarbon chain of a soap molecule also.
