Index of refraction of a substance =
(speed of light in vacuum) / (speed of light in the substance)
Index in quartz = (2.9979 x 10⁸ m/s) / (2.0567 x 10⁸ m/s)
<em>Index = 1.4576 </em> (no units)
Answer: sorry but I can’t help
Explanation:because I can’t see it
Assuming all the landmasses continue to move towards a sort of epicenter, large mountain ranges would appear in Africa and Europe.
Answer:
Explanation:
This problem is based on conservation of rotational momentum.
Moment of inertia of rod about its center
= 1/12 m l² , m is mass of the rod and l is its length .
= 1 / 12 x 4.6 x .11²
I = .004638 kg m²
The angular momentum of the bullet about the center of rod = mvr
where m is mass , v is perpendicular component of velocity of bullet and r is distance of point of impact of bullet fro center .
5 x 10⁻³ x v sin60 x .11 x .5 where v is velocity of bullet
According to law of conservation of angular momentum
5 x 10⁻³ x v sin60 x .11 x .5 = ( I + mr²)ω , where ω is angular velocity of bullet rod system and ( I + mr²) is moment of inertia of bullet rod system .
.238 x 10⁻³ v = ( .004638 + 5 x 10⁻³ x .11² x .5² ) x 12
.238 x 10⁻³ v = ( .004638 + .000015125 ) x 12
.238 x 10⁻³ v = 55.8375 x 10⁻³
.238 v = 55.8375
v = 234.6 m /s
Answer:
330 kg for high density liquid
255 kg for low density liquid
Explanation:
Density is defined as mass per unit volume hence expressed as p=m/v where p is density, m is mass and v is volume. Making m the subject of the formula then m=pv
The volume of the given container is given by lwh where l is length, w is width and h is height. Substituting 3m, 0.4 m and 0.5 m for l, w and h then volume is 3*0.4*0.5=0.6 cubic metres
Since the liquids are mixed equally, volume for each is 0.6/2=0.3 cubic metres
Mass of first liquid will be 1100*0.3=330 kgs
Mass for other liquid whose density is 850 kg/m3 will be 0.3*850= 255 Kgs
