The quantity that is calculated from the product of the force and the distance traveled due to the force is called work.  It has SI units of Joules (J) which is equivalent to Newton-meter (N-m). It is the energy that happens when an object is being moved by an external force.
        
             
        
        
        
The answer is adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients.
Explanation:
Despite that adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients is one of the best strategy to reducing weight, most time it is very difficult for those that want to reduce or control their weight to discipline themselves enough to follow these routine. But one an individual that want to loose weight or live a healthy lifestyle is able to follow these procedures he/she will surely loose weight. 
 
        
             
        
        
        
Answer:
Thus the time taken is calculated as 387.69 years
Solution:
As per the question:
Half life of  = 28.5 yrs
 = 28.5 yrs
Now,
To calculate the time, t in which the 99.99% of the release in the reactor:
By using the formula:

where
N = No. of nuclei left after time t
 = No. of nuclei initially started with
 = No. of nuclei initially started with

(Since, 100% - 99.99% = 0.01%)
Thus

Taking log on both the sides:


t = 387.69 yrs
 
        
             
        
        
        
Answer: 154.08 m/s
Explanation:
Average acceleration  is the variation of velocity
 is the variation of velocity   over a specified period of time
 over a specified period of time   :
:
 
Where:
 
 being
 being  the initial velocity and
 the initial velocity and  the final velocity
 the final velocity

Then:

Since  :
:

Finding  :
:


Finally:
