Answer:
A. a meteor traveling unhindered through space
Explanation:
v = v₀ + at
v = final speed, v₀ = initial speed, a = acceleration, t = elapsed time
Given values:
v₀ = 0m/s (starts from rest), a = 9.81m/s², t = 3s
Plug in and solve for v:
v = 0 + 9.81(3)
v = 29.4m/s
The global warming is the uniform heating of the globe due to the effect of greenhouse gases.
Answer: Option B
<u>Explanation:</u>
Global warming is thus the theory that says that earth is warming up with an increase in temperature over time due to increment in the greenhouse gases.
These are greenhouse gases that are getting increased due to the human activity or say over exploitation of the natural resources. The heating of the globe has caused ozone layer depletion which is also causing warming.
I believe it is, All of the above.
Average speed = (distance covered) / (time to cover the distance)
Average speed = (4 meters) / (5 seconds)
Average speed = (4/5) (meters/seconds)
Average speed = 0.8 m/s
