Answer:
He started factories and mills. He created World's first water- powered mill at Cromford, where he employed more than 200 people. This was just the beginning of the many factories which he would later set up. Because of this, Arkwright was known as the father of the modern industrial factory system........Hope you got it
 
        
             
        
        
        
Answer:
Actually, many single-celled organisms have a structure that facilitates mobility within the cell's environment. These often take the form of flagella, thin structures that emanate from the cell wall and push into the outer environment

Answer : The molal freezing point depression constant of liquid X is, 
Explanation :  Given,
Mass of urea (solute) = 5.90 g
Mass of liquid X (solvent) = 450 g  = 0.450 kg
Molar mass of urea = 60 g/mole
Formula used :  

where,
 = change in freezing point
 = change in freezing point
 = freezing point of solution =
 = freezing point of solution = 
 = freezing point of liquid X =
 = freezing point of liquid X = 
i = Van't Hoff factor = 1 (for non-electrolyte)
 = Molal-freezing-point-depression constant = ?
 = Molal-freezing-point-depression constant = ?
m = molality
Now put all the given values in this formula, we get


Therefore, the molal freezing point depression constant of liquid X is, 
 
        
             
        
        
        
The law of conservation of energy states that energy is never created or destroyed only converted.
