Answer:
Final momentum after a head on collision is -2kgm/
Explanation:
One ball moves to the right and the other moves opposite and momentum is a vector quantity so that considering the direction
Initial momenta are P₁=2x3=6kgm/s P₂=4x(-2)=-8kgm/s
Final momentum is the vector sum of P(final)= 6-8= -2 kgm/s
Answer: The elimination of seasonal variations
Explanation:
Since the cosmic catastrophic event which occurred led to the tilt of the Earth's axis relative to the plane of orbit to increase from 23.5° to 90°, the most obvious effect of this change would be the elimination of seasonal variations.
It should be noted that seasonal variation refers to the variation in a time series that's within a year which is repeated. The cause of seasonal variation can include rainfall, temperature, etc.
The answer is B hope this helps
The choices for this question can be found elsewhere and as follows:
short hill.
tall hill.
tightly coiled spring.
<span>stretched-out spring.
</span>
I think the best answer is the third option. A high amplitude sound wave can best be compared to a tightly coiled spring. <span>A </span>high<span> energy </span>wave<span> is characterized by having a </span><span>high amplitude.</span>
