<h3>
Answer:</h3>
Wavelength-1.805 × 10^-12 m
Type of electromagnetic radiation-Gamma rays
<h3>
Explanation:</h3>
We are given the following;
Energy of a photon is 1.10 × 10^-13 Joules
We are required to calculate the wavelength's of photon
We need to know that the energy of a photon is calculated by the formula;
E = hf, but f = c/λ
Therefore;
E = hc/λ , where h is the plank's constant,6.623 × 10^-34 J-s, c is the speed of light, 2.998×10^8 m/s and λ is the wavelength.
Rearranging the formula;
λ=hc/E
Thus,
λ = (6.623 × 10^-34 J-s × 2.998×10^8 m/s) ÷ 1.10 × 10^-13 J
= 1.805 × 10^-12 m
- Therefore, the wavelength of the photon is 1.805 × 10^-12 m
- The most probable electromagnetic wave with the wavelength 1.805 × 10^-12 m is gamma rays
- This is becasue the wavelength of gamma rays is less than 1 nm or 10^-9 m

Answer:
14 g.
Explanation:
- From the figure attached:
<em>the solubility of lead(II) nitrate, Pb(NO₃)₂, in 100 grams of water has a temperature of 30ºC is </em><em>(66 g).</em>
When beaker containing 80 grams of lead(II) nitrate, Pb(NO₃)₂, in 100 grams of water has a temperature of 30ºC.
<em>∴ The grams of the salt are undissolved, on the bottom of the beaker are </em><em>(14 g).</em>
A few notes.
- Stellar evolution is the process by which a star changes over the course of time.
- Nuclear fusion powers a star for most of its existence
- Stellar evolution is not studied by observing the life of a single star, as most stellar changes occur too slowly to be detected, even over many centuries.
Answer:
heat and pressure
Explanation:
because it happens under heat and pressure.
