Your answer would be D- Knowledge of the environment.
I hope this helped... ;)
By definition, acceleration is the change in velocity per change of time. As time passes by, the time increases in value. So, when the acceleration is decreasing while the time is increasing, then that means that the change of velocity is also decreasing with time. So, optimally, the initial velocity and the velocity at any time are very relatively close to each other,
There are two every year – in September and March – when the Sun shines directly on the Equator and the length of day and night is nearly equal.
Answer:
2.1J
Explanation:
Given parameters:
Spring constant = 128N/m
Compression = 0.18m
Unknown:
Potential energy of the spring = ?
Solution
The potential energy of the spring is the elastic potential energy within the spring.
To solve this;
Elastic potential energy = 
k e²
k is the spring constant
e is the compression
Now;
Elastic potential energy = x 128 x 0.18² = 2.1J
