Answer:
Bob's angular speed is the same as that of lily
Explanation:
Because for a carousel the angular speed remains the same since velocity at center and edge are the same
Answer: a. 53cm b. Diverging c. 0.02dioptres
Explanation:
Since the person in question cannot see far object clearly, it shows that the individual is suffering from myopia (short sightedness).
If the object distance (u) is 53cm. for the person to be able to see far way, it means the image must be at infinity. This shows image distance v is infinity. Using the lens formula
1/f = 1/u+1/v
1/f = 1/53 + 1/Infinity
1/f = 1/53 + 0
f=53cm
b) The lens used is concave lens (diverging lens) to diverge all rays outwards
c) Power of a lens P will be 1/53.
P = 0.02dioptres
The gravitational pull is weaker.
Kinematics is the branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved. :)
According to the octet rule, if an atom has fewer than 8 electrons in the outer most energy level, it will react with other nearby atoms to give, receive or share electrons until it has a full outer shell.
The octet rule refers to the tendency of atoms to prefer eight electrons in their valence shell.
If the atom has less than 8 electrons, the atoms tend to react to form more stable compounds.
The discussion of the octet rule does not consider d or f electrons. It is useful for main group elements because only s and p electrons participate in the octet rule.
Atoms are reacted to be as stable as possible. Complete octets are very stable because all orbitals are full. Since atoms with higher stability have less energy, reactions that increase the stability of atoms release energy in the form of heat or light.
