Answer:
KE=2.3 x 10⁻¹⁹ J
Explanation:
Given that
λ = 544 nm
λ' = 485 nm
The kinetic energy KE given as
KE= E - Ф
Where


h= 6.626 x 10⁻³⁴
C=3 x 10⁸ m/s
Now by putting the values


KE=2.3 x 10⁻¹⁹ J
This is kinetic energy.
Answer:
100 percent
Explanation:
Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth the relative humidity very rarely falls below 30 percent.
<h2>True</h2>
Scientists devised the geologic time scale after observing changes in fossils as they progressed from oldest to youngest sedimentary strata. Eons, eras, periods, and epochs make up the geologic time scale.
The third option seems correct. Using any bag more than once will help in decreasing the carbon foot print.
This isds beause, if you use paper bag once only, then paper bag is being utilised and more and more paper is being used. So the best way is to use the bag more than once, whichever bag u are using.
