The Sun is going down, and most of the land is dark, still we can see silhouettes and outlines of objects because some light is still scattered in the atmosphere. I hope this helps you.
Answer:
1402.73 m
Explanation:
Mass of Azurite=3.25 lb
Percent of copper in AZurite mineral=55.1%
Diameter of copper wire,d=0.0113 in
Radius of copper wire=
Density of copper=
1 lb=454 g
3.25 lb=
Mass of Azurite=
Mass of copper=
Density=
Using the formula
Volume of copper wire=
Radius of copper wire=
1 in=2.54 cm
Volume of copper wire=
Using the formula
1 m=100 cm
Hence, the length of copper wire required=1402.73 m
Answer: Option (c) is the correct answer.
Explanation:
Physical properties are the properties in which there is no change in chemical composition of a substance. On the other hand, chemical properties are the properties which change the chemical composition of a substance.
For example, when water boils at 
then it changes into vapor state whereas when water freezes at 
then it changes state from liquid to solid.
This means only physical state of water is changing and there is no change in chemical composition of water.
Hence, we can conclude that best option describing given information is that these are the physical changes water undergoes.
Answer:
11.5 m
Explanation:
First, find the time it takes to land.
Given:
Δy = -1.5 m
v₀ = 10 sin 37° m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
-1.5 m = (10 sin 37° m/s) t + ½ (-9.8 m/s²) t²
-1.5 = 6.02 t − 4.9 t²
4.9 t² − 6.02 t − 1.5 = 0
Solve with quadratic formula:
t = [ -(-6.02) ± √((-6.02)² − 4(4.9)(-1.5)) ] / 2(4.9)
t = 1.44
Now find how far it moves horizontally in that time:
Given:
t = 1.44 s
v₀ = 10 cos 37° m/s
a = 0 m/s²
Find: Δx
Δx = v₀ t + ½ at²
Δx = (10 cos 37° m/s) (1.44 s) + ½ (0 m/s²) (1.44 s)²
Δx = 11.5 m
The cat lands 11.5 meters from the table.
Answer:
Explanation:
RGB values are a combination of three different numerical values which represent Red Green and Blue which range from 0 to 255. When combining two separate colors with RGB values you would simply need to add each of these numerical values together to form an entirely new RGB value. For example,
(105, 200, 0) + (203, 30, 186) = (255, 230, 186)
You can see in the example above that every number in the first color is added to the number in the same position within the second color. If the addition of two numbers goes above 255 then the value maxes out at 255 and stays as is.
