Answer:
These electrons are "bonding pairs."
Explanation:
Two atoms share a pair of two valence electrons between them to form a covalent bond. (Of course they can share more than one pairs to produce a double, or a triple bond.) These valence electrons are called "bonding pairs."
In contrast, if a pair of valence electrons on an atom are not shared with another atom, that pair of valence electrons is called a "lone pair".
Ionizing radiation released from nuclear accidents does cause cancer but there have been only a small number of accidents so determining if it is not safe is a matter of opinion.
Answer:
L = 3.35 m
Explanation:
given,
mass of the block = 0.2 Kg
spring constant = 1.40 kN/m
until spring compressed = 10 cm
inclination of ramp = 60°
now,
initial potential energy of spring = (work done by friction) + (final gravitational potential energy of block)
L = 3.35 m
