21N
Explanation:
Given parameters: 
Mass of wagon = 14kg
Acceleration = 1.5m/s²
Unknown: 
Net force on wagon = ? 
Solution: 
Force is a pull or push on a body that causes a body to change its state. It is expressed as:  
                  Force = mass  x acceleration
   Force on wagon = 14 x 1.5 =  21N

Answer : Yes, distance measurements based on the speed of light used for objects in space.
Explanation :  A light year is measurement  of distance  that light travel in a one year. 
In a one year light travels 9460000000000 kilometer.
 We know that, speed of light is 
and  time is 31536000 seconds in 1 year
so, distance = speed of light X time 
Now, the light year is 
Example : The nearest star to earth is about 4.3 light year away.
