Answer:
The answer is "Landfill use"
Explanation:
Landfill use associated with energy producing technologies can decrease land fertility.
The purpose of a landfill is to isolate waste from its surrounding environment, preventing water contamination and contact with air. However, landfills are not built to decompose trash
 
        
             
        
        
        
Answer:
a. 
b.  must be the minimum magnitude of deceleration to avoid hitting the leading car before stopping
  must be the minimum magnitude of deceleration to avoid hitting the leading car before stopping 
c.  is the time taken to stop after braking
 is the time taken to stop after braking
Explanation:
Given:
- speed of leading car,  
- speed of lagging car,  
- distance between the cars,  
- deceleration of the leading car after braking,  
a.
Time taken by the car to stop:

where:
 , final velocity after braking
 , final velocity after braking
 time taken
 time taken


b.
using the eq. of motion for the given condition:

where:
 final velocity of the chasing car after braking = 0
 final velocity of the chasing car after braking = 0
 acceleration of the chasing car after braking
 acceleration of the chasing car after braking

 must be the minimum magnitude of deceleration to avoid hitting the leading car before stopping
 must be the minimum magnitude of deceleration to avoid hitting the leading car before stopping 
c.
time taken by the chasing car to stop:


 is the time taken to stop after braking
  is the time taken to stop after braking

Answer:
9m^3
Explanation:
Given data
volume  v1=  3m^3
volume  v2=  ???
Temperature T1= 20.0°C.
Temperature T2= 60.0°C.
Applying the relation for temperature and volume
V1/T1= V2/T2
substitute
3/20= V2/60
3*60= V2*20
180= 20*V2
180/20= V2
V2= 9m^3
Hence the final volume is 9m^3
