1. If an object starts at 0 m/s and 0.0001 seconds later the object is travelling at 400 m/s what is the objects acceleration?

4 x 10⁶m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time  = 0.0001s

Final velocity  = 400m/s

Unknown:

Acceleration of the object  = ?

Solution:

Acceleration is the rate of change of velocity with time;

 Acceleration  =  

 Acceleration  =   = 4 x 10⁶m/s²

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

could i give you a exaplo that could you?
