<span>The correct answer should be a genetic drift. Mutations usually occur over a relatively short period of time and usually start with a single unit that transfers the mutation when they procreate. Genetic drifts separate entire populations and in time create new species that cannot procreate with the original species from whence they came.</span>
The answer is 111.
Using Newton's Second Law, F=ma, plugging known values in we get:
F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N
<span>The answer is D. mountains have been eroding for millions of years. The Appalachian Mountains is an older group of fold mountains. It is much older than the Himalays that do not exibit this rounded shape. As tectonic forces enable mountain building, forces of weathering, erosion and mass wasting are constantly eating away at them. </span>
Answer:
No, it will not affect the results.
Explanation:
For elastic collisions in an isolated system, when a collision occurs, it means that the systems objects total momentum will be conserved under the condition that there will be no net external forces that act upon the objects.
What that means is that if the pucks start spinning after the collision, we are not told that there was any net external force acting on the puck and thus momentum will be conserved because momentum before collision will be equal to the momentum after the collision.
