Answer:
Eyeglass lenses will almost always be convex on the outer surface, the one farthest from the eye, simply to fit it to the curvature of the face.

The speed with which the car going just before the driver slammed the brakes is 25.28 m / s, if the car skids to halt at a uniform rate of -9.4 m/s^2.
v² = u² + 2 a s
v = Final velocity
u = Initial velocity
a = Acceleration
s = Displacement
v = 0
a = - 9.4 m / s²
s = 34 m
0 = u² + ( 2 * - 9.4 * 34 )
u² = 639.2
u = 25.28 m / s
Deceleration is the slowing down of an object. It can be negative acceleration or positive acceleration. Deceleration is negative if the object moves in positive direction and it is positive if the object moves in negative direction.
Therefore, the speed with which the car going just before the driver slammed the brakes is 25.28 m / s

Light travels best through empty space because there is nothing to block/disrupt its path.
Answer:
If this explosion is occurring in a closed environment this 'rule' would be:
The conservation of momentum.
Explanation:
In a close system which means the experiment is isolated from the surrounding environment and therefore not allowed to interact with its external space will have the same amount of momentum at the end of the experiment as the beginning by the equation of p=mv, p is momentum, m is mass and v is velocity.
