Answer: acceleration = slope  graph velocity vs time
Explanation: if you have the graph of velocity vs time , the slope of that graph equals the acceleration of our object assuming constant acceleration...but remenber por a real object is really hard to keep constant acceleration
 
        
                    
             
        
        
        
Answer:
The work done on the suitcase is, W = 1691 J
Explanation:
Given data,
The force on the suitcase is, F  = 89 N
The distance Russell dragged the suitcase, S = 19 m
The work done on the suitcase by Russell is equal to the work done on the suitcase to overcome the friction
The work done on the suitcase by Russell is given by the formula
                           W = F · S
Substituting the given values,
                            W = 89 N x 19 m
                            W = 1691 J
Hence, the work done on the suitcase is, W = 1691 J
 
        
             
        
        
        
Answer:
Explanation:
The formula for this, the easy one, is
 where No is the initial amount of the element, t is the time in years, and H is the half life. Filling in:

Answer:
They both tend to develop during the spring (March-June), reach peak intensity during the late autumn or winter (November-February), and then weaken during the spring or early summer (March-June)
