Answer:

mass of carbohydrate = 30g

mass of protein = 8g

mass of fat = 10g

mass of alcohol 3g

Caloric value of carbohydrate = 4

Caloric value of protein = 4

Caloric value of fat = 9

Caloric value of alcohol = 6.9

The kcalorie of the meal = mass *caloric value of each food item

Kcalorie value =

30*4+8*4+10*9+3*6.9

Kcalorie = 120+32+90+20.7

Kcalorie = 262.7

Most of the ultraviolet radiation reaching the surface of the earth is UV-A radiation, which has a wavelength range of 315 nm to
posledela

Answer:

6.1 ×10^-19 J

Explanation:

From E= hc/λ

h= planks constant = 6.6×10^-34 Js

c= speed of light = 3×10^8 ms^1

λ= wavelength = 325 nm

E= 6.6 × 10^-34 × 3×10^8/325 × 10^-9

E= 0.061 × 10^ -17 J

E= 6.1 ×10^-19 J
