Answer:
K =6.697 Kg/s²
Explanation:
Given: 
delta m =41 g = 0.041 kg
delta x = 6cm = 0.06m
g = 9.8 m/s²
according to the given formula 
 K = delta m g /delta x
K = (0.041 kg × 9.8 m/s²) / 0.06m
K =6.697 Kg/s²

Acceleration can be defined as the rate of change in the velocity of an object. Option C is correct.
<h3>What is 
Acceleration?</h3>
- It is defined as the rate of change in velocity. 
- It can also be defined as the rate of change in position in a particular direction.

Where,
 - acceleration
 - acceleration 
 - change in velocity
 - change in velocity
 - time
 - time 
Therefore, acceleration can be defined as the rate of change in the velocity of an object.
