Answer:
The correct answer is D.
D:The surface of the coating allows light from the room to pass through but blocks the light from the screen.
Explanation:
Glare is produced on a computer screen when light from some external source reflects on the screen.
Anti-glare coating do not absorb light to reduce glare but they actually reduce glare by encouraging the light from the room to pass through the screen so that less light is reflected. Polarized lenses absorbs light to reduce glare, not anti-glare coating.
Answer:
Hydrated iron(III) oxide, or ferric oxide
Explanation:
What does this mean? What do you need help with?
It's simple.
We know force is the rate of change in momentum.
So F=(mv-mu)/t or F=m(v-u)/t
=1200*(25-10)/5=3600N
Answer:
R=3818Km
Explanation:
Take a look at the picture. Point A is when you start the stopwatch. Then you stand, the planet rotates an angle α and you are standing at point B.
Since you travel 2π radians in 24H, the angle can be calculated as:
t being expressed in hours.
From the triangle formed by A,B and the center of the planet, we know that:
Solving for r, we get:
