Answer:
The angle of launch of the rubber band affects the initial velocity. The more the rubber band is stretched the more force it applies to return to equilibrium and the more kinetic energy that results in. 
 
        
             
        
        
        
Answer:
As a result, light travels fastest in empty space, and travels slowest in solids. In glass, for example, light travels about 197,000 km/s.

Answer:
  a = - 9.8 j ^   m/s²
Explanation:
This is a projectile launch problem, they give us the initial velocity in the two components
          v₀ₓ = 17.1 m / s
           = 14.7 m / s
 = 14.7 m / s
 They indicate that the only acceleration that exists is the acceleration of gravity, which acts in the direction towards the center of the Earth, in general in a coordinate system it coincides with the direction of the y axis.
            a = - g j ^
            a = - 9.8 j ^  m /s²
 
        
             
        
        
        
Answer:
I think its a fuse because everything else makes sense and is used in electrical circuits and the fuse is the only one that stands out to me  ¯\_(ツ)_/¯
 
        
             
        
        
        
Answer:
Earth's average surface gravity is about 9.8 meters per second per second. ... The Moon's surface gravity is weaker because it is far less massive than Earth. A body's surface gravity is proportional to its mass but inversely proportional to the square of its radius.
