A microwave oven uses electromagnetic radiation to heat water molecules in food or drink. This radiation has a frequency of 2.45 x 10⁹ Hz. Calculate its energy
Answers
Answer:
1.62 × 10⁻²⁴ J
Explanation:
Step 1: Given and required data
Frequency of this radiation (ν): 2.45 × 10⁹ Hz (2.45 × 10⁹ s⁻¹)Planck's constant (h): 6.63 × 10⁻³⁴ J.sStep 2: Calculate the energy (E) of this electromagnetic radiation
We will use the Planck-Einstein's relation.
E = h × ν
E = 6.63 × 10⁻³⁴ J.s × 2.45 × 10⁹ s⁻¹ = 1.62 × 10⁻²⁴ J

Answer:
[tex]\boxed {\boxed {\sf A. \ 19,320 \ kg/m^3}}[/tex]
Explanation:
We want to find the density. The formula is mass over volume.
[tex]\rho = \frac{m}{v}[/tex]
The mass is 500 kilograms. The volume is 0.026 cubic meters.
[tex]m= 500 \ kg \\v=0.026 \ m^3[/tex]
Substitute the values into the formula.
[tex]\rho= \frac{ 500 \ kg}{ 0.026 \ m^3}[/tex]
Divide.
[tex]\rho = 19230.7692 \ kg/m^3[/tex]
This is just about equal to 19,320 kg/m³, so choice A is correct.
Answer:
A) 19230 kg/ m3
Explanation:
divided it's mass by its volume ti get it's density
500/0.026 = 19230
