Answer:
B. The number of electrons emitted from the metal per second increases.
Explanation:
Light consists of photons . Energy of each photon depends upon frequency of light . The increase in intensity increases the number of photons . It does not increase energy of photons .
So if a high intensity light falls on a photosensitive plate , each photon ejects one electron . So number of electrons increases if we increase intensity of photon. It does not increase kinetic energy of ejected electrons . Work function depends upon the nature of plate.
Equilibrium is when the opposing forces or influences are balanced. So it would be E!
If the Earth's axis were 'straight' ... pefectly perpendicular to the ecliptic
plane ... then:
-- Day and night would be the same length ... every day of the year,
everywhere on Earth !
-- There wouldn't be any seasons, anywhere. There might still be some
'weather' ... cloudy days, sunny days, occasional rain, wind etc. But
there would be no average change during the year. No hot months or
cold months. In any one place, the weather would always be generally
the same, every day, all year. Everywhere all around the equator would be
generally the hottest on Earth, and the local climates would generally get
cooler as you moved away from the equator and toward the poles.
<span>The flower width data were collected at about the same time
every day. </span>
According to the research, the responder made with the same
query as this question it is:
<span><span>
1.
</span>The flower width data were collected at about
the same time every day. </span>
Why this choice because, the study is delving into the
effects of morning temperatures on flower width hence, if the scientists
collect flower at the same time –hour or minutes everyday during the period of
the study the variable of time is not allotted from sunrise period to high noon
since it defines time as morning, the variant of time is only inapt.
