Answer:
By adding a surface that increases friction? Such as outdoor mats(rough ones), which increases friction between the bottom of the boots and the surface.
The answer is A. this process is only in the research phase
The process of fusion involves merging of atomic nuclei to
form heavier nuclei resulting in the release of enormous amounts of energy.
Fusion takes place when two low mass isotopes, typically isotopes of hydrogen,
unite under conditions of extreme pressure and temperature. Scientists continue
to work on controlling nuclear fusion in an effort to make a fusion reactor to
produce electricity. However, progress is slow due to challenges with
understanding how to control the reaction in a contained space.
Answer:
the HOMO-LUMO energy difference in ethylene is greater than that of cis,trans−1,3−cyclooctadiene
Explanation:
The λmax is the wavelength of maximum absorption. We could use it to calculate the HOMO-LUMO energy difference as follows:
For ethylene
E= hc/λ= 6.63×10^-34×3×10^8/170×10^-9= 1.17×10^-18J
For cis,trans−1,3−cyclooctadiene
E= hc/λ=6.63×10^-34×3×10^8/230×10^-9=8.6×10^-19J
Therefore, the HOMO-LUMO energy difference in ethylene is greater than that of cis,trans−1,3−cyclooctadiene
