Answer:
Based on color theory it would come out as brown
Explination:
Basic color theory states the primary colors are red yellow and blue. Expanding that to the rainbow you know. Red plus yellow equals orange. Yellow plus blue equals green. And blue plus red equals purple. Red and Green are opposite colors and when you combine opposite colors you get brown
Answer:
3.09 cm /sec.
Explanation:
Speed = distance / time taken
= <u>186×220× 91.</u><u>44</u><u> </u> cm/sec
1×14×86400
= 3.09 cm /sec.
Note: 1 yard = 91.44 centimeters
And 1 day= 24×60×60= 86400 seconds.
Answer: 0.86 × 10^14
Explanation:
Given the following :
Radius of proton = 1.2 × 10-15 m
Radius of hydrogen atom = 5.3 × 10-11 m
Density of proton could be calculated thus:
Mass of proton = 1.67 × 10^-27 kg
Using the formula :
(4/3) × pi × r^3
(4/3) × 3.142 × (1.2 × 10^-15)^3 = 7.24 × 10^-45
Density = mass / volume
Density = (1.67 × 10^-27) / ( 7.24 × 10^-45)
= 0.2306 × 10^18
Density of hydrogen atom:
Mass of hydrogen atom= 1.67 × 10^-27 kg
Using the formula :
(4/3) × pi × r^3
(4/3) × 3.142 × (5.3 × 10^-11)^3 = 6.24 × 10^-31
Density = mass / volume
Density = (1.67 × 10^-27) / ( 6.24 × 10^-31)
= 0.2676 × 10^4
Ratio is thus:
Density of proton / density of hydrogen atom
0.2306 × 10^18 / 0.2676 × 10^4 = 0.8617 × 10^14
invasive species that are bad for the world are usually non-native invasive species. These plants colonize habitats, and exclude the native plants and animals. most plants take over to much land and can cause problems
