Answer:
163.44 g
Explanation:
We know that one ton is equal to 2000 lbs and one lb is equal to 454 grams.
Solution:
1.80 × 10∧-4 ton× 2000 lb/ton× 454 g/lb
1.80 × 10∧-4 ton× 2× 10³lb/ton× 454 g/lb
1634.4 g/ 10 = 163.44 g
Answer:
The correct option is;
A. Corresponding with orange light, is the wavelength that blue solutions absorb the most
Explanation:
The wavelength of 633 nm is the wavelength of red light emitted by the helium-neon laser also known as the He-Ne laser
According to absorption spectroscopy and the color wheel, a solution or drink sample that is efficient at absorbing light having a wavelength of 633 nm will appear blue, because, light at 633 nm is red and very close to orange which is the complementary color blue light.
we will use the root mean squared speed of oxygen formula
v= (3RT) / M
T= vM/3R
where
v =1.12x104 m/s; velocity
R= (8.31447 kg m2 s-2 K-1 mol-1) gas constant
M = 0.0319988 kg/mol; molar mass of oxygen
substituting the given values, we will get
T(K)= 14.37K or -258.78 C
Oxygen molecules speed of 1.12x104 m/s is at temperature -258.78C.
The mixture of rock particle sand humus is called the soil.
If soil contains greater proportion of big particles it is called sandy soil. If the proportion of fine particles is relatively higher, then it is called clayey soil. If the amount of large and fine particles is about the same, then the soil is called loamy.
