Answer:
Resonance structures have <u> </u><u>same</u><u> </u> connectivity of atoms and <u> differ only in</u> distribution of electrons.
Explanation:
Atoms supply the electrons from their outer electron shells. Electrons are found free in nature and are grouped around the nucleus into shells. Electrons can be further explained as negatively charged subatomic particle. Electrons have properties of both particles and waves and they can be moved around.
Resonance structures are imaginary structures and not all of them are created equally. Resonance structures have two or more possible electron structures, and, the resonance structures for a particular substance sometimes have different energy and stability. When resonance structures are identical, they are important descriptions of the molecule. The position of the atoms is the same in the various resonance structures of a compound, but the electrons are distributed differently around the structure.
Answer:
Explanation:
Consider downward displacement first .
downward displacement h = 38 m .
downward acceleration = g
downward initial velocity u = 0
h = ut + 1/2 g t ²
38 = 0 + 9.8 t ²
t = 1.97 s
During this period , there will be horizontal displacement with initial velocity u = 10 m /s and acceleration a = 1.6 m /s²
s = ut + 1/2 a t²
= 10 x 1.97 + .5 x 1.6 x 1.97²
= 19.7 + 3.10
= 22.8 m
If you drop a ball off a building it increases its speed by 10 m/s so in 3 seconds it’s speed would be 30 m/s and it’s distance would be 45m
Explanation:
This due to thermal insulation of some of the roof.
An insulator is body is a poor conductor of heat and will require high thermal energy to cause temperature changes.
- A house with a roof that is thermally insulated will have poor heat conduction.
- Since little heat is conducted, there wont be enough thermal energy to melt the snow.
- Thermal energy is directly related to heat.
- A house that is not insulated will absorb a lot of heat.
- This will cause the snow to melt very fast.
