As weight =w =mg
g= gravitational acceleration on mercury = 3.7m/sec2
Mass of person =m= 70 kg
So w =(70kg)(3.7m/sec2)
w= 259 kgm/sec2
W= 259 N
Answer:
The answer is explained below in explanation
Explanation:
Whenever light falls on a colored surface, that color of light is reflected by the surface and all the other colors are absorbed. That is a black body appears black in all lights, because it absorbs every color and a white surface appears to be of the color of the light shone upon it because it is the mixture of all colors of light and reflects every color. The eyes only see the reflected light colors. The absorbed colors are not apparent to the eyes.
<u>Hence, when the white bulb is seen through red sunglasses, it does look like red to our eyes, while all the other colors are absorbed by the sun glasses.</u>
