the worst because its not enough habitat and when the cutting down a whole lot of rainforest at a time which is killing animals escpecialy rainforest animals
Answer:
The right solution is:
(a) 2.87 eV
(b) 1.4375 eV
Explanation:
Given:
Wavelength,
= 433 nm
Potential difference,
= 1.43 V
Now,
(a)
The energy of photon will be:
E =
=
or,
=
=
(b)
As we know,
⇒
By substituting the values, we get
⇒
⇒
or,
⇒
⇒
100 J
Explanation:
multiply the force by the distance
20 N x 5 meters = 100 J
