Answer:
c = λ f
c is the speed of light, λ the wavelength in meters, and f equals the frequency in cycles per second.
Explanation:
<span>I'd chose D. In all five years of the study, the control resulted in the least soil erosion as well as substantially less water loss compared to the two treatment situations. </span>
Answer: capsule and fimbriae
Explanation:
Many prokaryotes have sticky outermost layer called the capsule.It is made up of polysaccharides and it helps them clinging to each other or to other surfaces around them.It also helps prevent the cell from drying out.
Fimbriae,also known as attachment pilus,used by bacteria to adhere to one and other,animal cells or to any inanimate objects.
Although ice is solid, as long as temperatures are above −20°C (−4°F) there is always a very thin layer of water on the surface that makes it slippery. Extra melted water from the rubbing between the blade and the ice vastly reduces the friction allowing the skater to glide across the ice with little effort.
Answer:
We have 0.0170 moles of butyric acid
Explanation:
Step 1: Data given
Density of butyric acid = 0.959 g/mL
Temperature = 20.0°C
Volume = 1.56 mL = 0.00156 L
Step 2: Calculate mass
Density = mass / volume
mass = density * volume
Mass = 0.959 g/mL * 1.56 mL
Mass = 1.496 grams
Step 3: Calculate Number of moles
Number of moles = mass / molar mass
Number of moles = 1.496 grams / 88.11 g/mol
Number of moles = 0.0170 moles
We have 0.0170 moles of butyric acid
