I think its C or D.
Einstein's Nobel winning photoelectric equation.
The higher the work function, the more energy needed to photoeject an electron from the surfface
Try D
Answer:
The second one
Explanation:
The second one is joining so it is the one which belongs to X, first one belongs to Z
Yeah!! It is better to decrease the speed of the vehicle so the ejection of gases would happen in slow manner.... then you can save your gasoline
Answer:
The work done by a particle from x = 0 to x = 2 m is 20 J.
Explanation:
A force on a particle depends on position constrained to move along the x-axis, is given by,
We need to find the work done on a particle that moves from x = 0.00 m to x = 2.00 m.
We know that the work done by a particle is given by the formula as follows :
So, the work done by a particle from x = 0 to x = 2 m is 20 J. Hence, this is the required solution.
