We can use the equation for kinetic energy, K=1/2mv².
Your given variables are already in the correct units, so we can just plug in the variables and solve for v. 
K = 1/2mv²
16 = 1/2(2)v²
16 = (1)v²
√16 = v
v = 4 m/s
Therefore, the velocity of a 2 kg mass with 16 J of kinetic energy is 4 m/s.
Hope this is helpful!
        
             
        
        
        
Answer:
a delta 
Explanation:
The landform produced at the location E where the Mississippi River enters the Gulf of Mexico is a delta. 
A delta is a depositional landform where a smaller body of water enters into a larger one. 
The Gulf of Mexico contains a larger body of water and as the Mississippi river enters into it, it splits up into many distributaries. 
So, this feature is a delta.  
 
        
             
        
        
        
Answer: C
14.75g
Explanation: 
Given that the half life time = 60.5s
Let No = initial mass = 59g
N = decayed mass 
At time t = 0, No = 59g
At time t = 60.5s,
N = No/2 = 59/2 
 = 29.5g
At time t = 121
N = 29.5/2 = 14.75g
Therefore N = 14.75g
 
        
             
        
        
        
Answer:As people get older, most become better able to regulate negative feelings and emphasize the positive.
Explanation: With age, your skin thins and becomes less elastic and more fragile, and fatty tissue just below the skin decreases. You might notice that you bruise more easily. Decreased production of natural oils might make your skin drier. Wrinkles, age spots and small growths called skin tags are more common.
