Answer:
In a climatological sense, dryness is a function of both annual rainfall and evaporation
Answer:
The frequency of photon is 0.75×10¹⁵ s⁻¹.
Explanation:
Given data:
Energy of photon = 5×10⁻¹⁹ J
Frequency of photon = ?
Solution:
Formula;
E = hf
h = planck's constant = 6.63×10⁻³⁴ Js
5×10⁻¹⁹ J = 6.63×10⁻³⁴ Js ×f
f = 5×10⁻¹⁹ J / 6.63×10⁻³⁴ Js
f = 0.75×10¹⁵ s⁻¹
The frequency of photon is 0.75×10¹⁵ s⁻¹.
Well you didn’t post any but I’m hoping that either plastic, lead, wood, glass, or paper, are an option.
A wooden spoon insulates itself and retains no heat, a mental spoon would retain heat, and probably burn your hand<span />
