Wavelength is also measured in metres (m) - it is a length after all. The frequency, f, of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz (Hz), since one hertz is equal to one wave per second.

1) This could cause accidents, injury or even death.
Answer:
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).
Explanation:
Answer:
feed = 220.77 kg/s; maximum production rate of solid crystal = 416 kg/s; the rate of supplying fresh feed to obtain the production rate = 1.6
Explanation:
Material or mass balance can be used to estimate the mass flow rates of all the streams in the diagram shown in the attached file.
Overall balance: 
Water: 
Using substitution method, we have:
= 220.77 kg/s
= 4.16 kg/s
The maximum production rate of solid crystal is 
= 10*4.16 = 416 kg/s
Around evaporator:
kg/s
Around the mixing point:
Solid crystal: 
Using the last two equations, we can obtain:
kg/s
The rate of supplying fresh feed to obtain the production rate is:
= 352.5/220.77 = 1.6
<span>CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair.</span>
