Answer:
I'm posting this so I can tell all of you that we should help him together in the comments because it seems we need more than one person to help him
1 nm = 1 * 10^-9 m
1mm = 1* 10^-3 m = 10^6 nm.
Thus, 10^6 nm = 1 mm
=> 261 nm = 261 * 1/10^6 mm = 261 * 10^-6 mm = 2.61 * 10^-4 mm. :)
Answer:
3.32m
Explanation:
Given frequency 90.5x10^6 Hz s-1
Speed light is 2.998x10^8m s-1
Divide speed of light over frequency.
Answer:
your answer is 30f
Explanation:
The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.
Among the given compounds, <span>CH3CH2CH2OH (1-propanol) will have maximum solubility in water.
Reason:
Solubility is based on the principle of 'Like dissolves Like'. Hence, water is a polar solvent, hence it will dissolve polar solvent to maximum extent. Among the listed solutes, </span>CH3CH2CH2OH has maximum polarity.
<span>
Further, </span>CH3CH2CH2OH is capable of displaying hydrogen bonding with water, while other compounds will not show hydrogen bonding. With reference to hydrogen bonding, it may be noted that when hydrogen atom is bonded to electronegative elements like O, N and F, it exhibits hydrogen bonding. Due to this, CH3CH2CH2OH will be readily soluble in water. <span>
