10 If velocity is positive, which would most likely yield a negative acceleration?
O O OO
A final velocity that is faster than an initial velocity.
A time that is less than a half hour.
An initial velocity that is faster than a final velocity.
A time that is greater than a half hour.

An initial velocity that is faster than a final velocity

Explanation:

The relationship between velocity and acceleration is given as follow;

Acceleration = Change in velocity / Time

Change in Velocity = Final Velocity - Initial Velocity

From the formular, time is not able to affect the sign of the acceleration.

A negative acceleration is also referred to as deceleration and this occurs when there is a drop in velocity.

A drop in velocity occurs when the initial velocity is faster than the final velocity.

beta decay is the answer

the answer is minerals.
