Answer:
The velocity of a falling object
Explanation:
The positive X axis is towards right and positive Y axis is towards up, so North direction is positive
A vector with less than 1 magnitude is not negative, because its magnitude may be in between 0 and 1 which is positive vector.
Any vector whose magnitude is greater than 1 is never be a negative vector.
The velocity of a falling object is towards bottom, that is towards negative Y axis. So that vector is negative.
Answer:
The answer to your question is: vf = 30 m/s
Explanation:
Data
vo = 15 m/s
a = 3.0 m/s²
t = 5 s
vf = ?
Formula
vf = vo + at
Substitution
vf = 15 + (3)(5)
vf = 15 + 15
vf = 30 m/s

Answer:
The Spanish philosopher George Santayana wrote, “those who cannot remember the past are condemned to repeat it.” When it comes to climate change, repeating the past is a luxury we can’t afford. If partisan politics continues to derail policy or if denial continues to win over science, it will mean irreversible changes to our planet. Future generations will look at ours as the one that didn’t have the courage to act, rather than the one that recognized the fierce urgency of the moment and met it head on.
With this in mind, we’ve created a climate change timeline highlighting the evolution of science, the intrusion of denial, and the sluggishness of policy over the past 200 years. Let’s learn from the mistakes of the past, so we can make tomorrow a brighter—but not hotter—future.
