Answer:
No
Explanation:
In the photoelectric effect,
The number of the electrons which are being emitted is directly proportional to the intensity of the light and is independent on the frequency of the incident radiation of the light which has the frequency greater than the threshold frequency.
Thus, on increasing the frequency of the light which is being shinned on the metal , there is no change in the electrons which are being emitted.
The energy carried by a single photon is given by
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of
, therefore its energy is
Answer:
Yes
Explanation:
Newton's third law
For every action, there is an equal and opposite reaction.
SO if the apple is falling 9.8 m/s2 then the same force is pushing against it.

The ammeter reading (current) will decrease.
V=IR
I = V/R
so I is inversely proportional to R, i.e. increasing R will cause I to decrease
