When force is applied and displacement is taking place, work is said to be done.

 

W = F x s

Work = Force x displacement

Columella auris in amphibians, reptiles, and birds, a bony or cartilaginous rod connecting the tympanic membrane with the inner ear and transmitting sound. It is homologous with the hyomandibular bone in fish.

The adult human body has 206 bones. An infant may have 270 bones at birth. Some of these fuse together as the infant grows. When some bones fuse and become one bone (most obvious examples are in the skull, sacrum and hip bones) the number of overall bones drops to the 206 bones that most adults have.

 

Of the 206 bones in the adult human body, more than half (106) are in the hands and feet. The adult skeleton consists of the following bones:28 skull bones (8 cranial, 14 facial, and 6 ear bones)the horseshoe-shaped hyoid bone of the neck which is the only bone that does not articulate (connect via a joint) to another bone26 vertebrae (7 cervical or neck; 12 thoracic; 5 lumbar or loins; the sacrum, which is five fused vertebrae; and the coccyx, which is four fused vertebrae)24 ribs plus the sternum or breastbone; the shoulder girdle (2 clavicles, the most frequently fractured bones in the body, and 2 scapulae)the pelvic bones (3 fused bones called the coxal bone, or Os Coxae)30 bones in each of the arms and legs (a total of 120)a few partial bones, ranging from 8-18 in number, which are related to joints

 

Interesting facts:

The hand has 27 bones, the foot has 26 and the face has 14.The longest bone in your body, the femur (thigh bone), is about 1/4 of your height. The smallest is the stapes (or stirrup) in the ear which is about 1/10 of an inch.Humans and giraffes have the same number of bones in their necks.Most of the bones in the body are in the hands and feet.

Excel is a spreadsheet program developed by Microsoft.

It has many advantages-

1. Makes calculation easier.

2. Large volume of data can be easily handled.

3. Can put graphs, tables, charts etc.

4. Data can be easily exported or imported from other software.

5. Worksheets or their parts can be exchanged, merged etc.

6. Formulas r easily calculated when data value r changed.

The Molecular Mass of a substance is the sum of the atomic masses of all the atoms in a molecule of the substance.

 

How to Calculate it?

If we have to find the molecular mass of HNO3 then...

The molecular mass of HNO3 = the atomic mass of H + the atomic mass of N + 3 x the atomic mass of O

= 1+14+48 = 63 u

Catalogs Discussion Forums -> Electricity -> why is static electricity invisible? -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Static Electricity is produced when one object takes negative charges from another object. For example, amber becomes negatively charged when rubbed with wool because amber attracts negative charges (electrons) and moves then from wool. As a rsult the amber becomes "negatively charged", and wool, due to the loss of negative charges, becomes "positively charged".

And I don't think that we see negative and positive charges moving here and there.....so, Static Electricity is invisible.

Catalogs Discussion Forums -> Physical Chemistry -> What's the difference between Na+ and Na? -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Na is a symbol of Sodium.

Atomic Number= 11

No. of Protons= 11

No. of Electrons= 11

No. of Neutons= 12

Valency= 1

 

Atom is stable as it has same no. of Protons and Electrons.

It has no charge and same goes to Na.

Na has no charge.

 

But in Na+, the charge is positive...as u can see + sign...

it means that in this, 1 electron is less and so it is positively charged.
