Answer:
Night vision goggles capture infrared light given off by heat
The correct answer would be A
When the light falls on a soap bubble spread on a water puddle, and a spectrum of color is observed due to constructive and destructive of light waves which means option (3) is correct. Light waves interfere into each other to produce a spectrum which consists of bright and dark fringes.
Answer:
10.6962 ml
Explanation:
the density of water is 1g/ml
if you devide the mass by density you get the volume the volume times density is equal to the mass so
84.5 grams devided by 7.9 is equal to 10.6962 ml.
if you do that times 1g/ml is equal to 10.6962 g/ml.
