Answer:
47628 kg/hr
Explanation:
Total area = 18*20 =360 ft^(2)
no .of snowflakes per minute = 1050*360 =378000
mass of snowflakes per minute = 378000*2.1*10^(-3) =793.8 kg/min
mass accumulated per hour = 793.8kg/min * 60min/hr =47628 kg/hr
 
        
             
        
        
        
<h2>Ratio of final kinetic energy to initial kinetic energy is 16.</h2>
Explanation:
Kinetic energy , KE = 0.5mv²
Here car speeds up to four times the initial speed, we need to find ratio of final kinetic energy to initial kinetic energy.
Final speed = 4 x Initial speed = 4v
Initial KE = 0.5mv²
Final KE = 0.5 x m x (4v)²
Final KE = 16 x 0.5 x m x v²
Final KE = 16 x Initial KE
Ratio of final kinetic energy to initial kinetic energy is 16.

 0.74in
Explanation:
Given parameters: 
length range of adult mosquito = 3.0 - 6.0mm
Smallest mosquito = 2.5mm 
Largest mosquito = 19mm 
Average mass range = 3.0 - 5.0mg 
Unknown: 
Length of largest known mosquito in inches = ? 
Solution; 
The length is the longest dimension. It is how long a body is. 
  The problem here is converting from mm to inches; 
  
 The length of the longest mosquito which is the largest is 19mm
  19mm to inches; 
      1mm = 0.039inches 
   19mm = 19mm x  = 0.74in
 = 0.74in
