Answer:
16.03m(2dp)
Explanation:
Ep=m x g x h
1100=7.0x 9.8( gravitational field strength) x h
Height= 1100/7.0 x 9.8
=16.03498542
= 16.03m (2dp)

Answer:
Work function,
Explanation:
Given that,
Frequency of light,
Kinetic energy of the ejected electrons,
We need to find the work function of the gold. Let it is W.
Using Einstein's photoelectric equation as follows :
So, the work function of gold is .
