Atypical wavelength of infrared radiation emitted by your body is 29 mm (2.9×10−2 m ). find the energy per photon of such radiation.

= 6.848 × 10^-24 J

Explanation:

Energy of a photon may be given by the Formula;

E = hf or E = hc/λ where E  is the c is the speed of light, h is the planks constant and λ is the wavelength.

The speed of light is 3 × 10^8 m/s, h is 6.626 × 10^-34 Js

Hence;

E = (6.62 × 10^-34 Js × 3× 10^8 m/s)/ 2.9 × 10^-2 m

   =6.848 × 10^-24 Joules

a sonic boom is a loud boom that breaks the sound barrier

explanation:

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
