<u>Answer:</u>
If 100 and 110 photons hit an atom and 63 electrons are emitted due to the threshold frequency
<u>Explanation:</u>
Because of the effect of threshold frequency. Both the times 63 electrons are only emitted and its due to the level of threshold value.
Threshold frequency is can be defined as the minimum frequency at which electrons will be getting emitted when it hits. If none of the electrons are getting ejected, this states that the frequency of the light is lesser than the threshold frequency
Answer choices ??? Or are there not any ?
Answer:
False
Explanation:
It is better to be logical when proving a point
Answer:
11.76Newtons
Explanation:
Workdone = Force * distance
Given
Workdone = 180joules
Distance = 15.3 metres
Required
Force
From the formula;
Force - Work/distance
Force = 180/15.3
Force = 11.76Newtons
Hence the required force is 11.76Newtons
Viscosity (The more viscous something is, the less it flows) e.g. water has a low viscosity, whereas honey has a high viscosity.
