Answer:
Radiation is the answer to your question
Transparent objects allow all the light to pass through them, translucent ones allow partial light to pass, whereas opaque ones allow no light to pass through.
Classical physics considered light to behave as a wave in all environments; it had a set amplitude, frequency etc. The problem was that this meant that there was a continuous variation in its properties, hence if the amplitude of the light was incresed by a bit, a phenomenon like the phhotoelectric one would become only marginally more apparent. However, in this case, there is a cutoff point which means that the only-wave theory had to be wrong.
Answer: C
Gauge pressure = 156 kPa ,
What is absolute pressure =?
We know that,
absolute pressure = gauge pressure + atmospheric pressure
Pabs = Pgauge + Patm
= 156 + 101.3 <em> </em><em> (since atm.pr. = 101.3 Kpa)</em>
<em> </em><em>= 257.3 KPa absoulte</em>
<em> approximately = 256 KPa absolue</em>
I believe it is acceleration
