Answer:
Assuming that the masses of the cars are the same
9 times
Explanation:
Kinetic energy can be computed using the formula:
Where:
KE = Kinetic energy
m = mass
v = velocity
As you can see in your problem, the velocity of the the first car mentioned is 3 times faster.
Looking at the the formula, velocity is raised to two (2). So if we put it in terms of equations this is how it will look:
Let v = velocity of the slower car
Car 1: velocity = (3v)
The increase is by a factor of 9.
Answer:
D. the spread of invasive species
E. increased crop growth
Explanation:
Climate change resulting from increased pollution levels in ecosystems causes a lot of damage to the surrounding area. High temperature increases global warming, chemical and industrial waste waters via run-off enter the oceans thereby increasing acidity and resulting in the destruction of aquatic biodiversity. However, species facing such climate change move from that habitat to another for their survival and spread there. While such crops have been identified that adapt the climate changes and continue to grow in that environment to.
Answer:
sexual reproduction
Explanation:
asexual would not result in any variability
The insects he sprayed will die therefore leaving the predators of the insects to decrease in population
