False , because its backwards
There will be more energy 'locked away' in a massive lorry that is moving at 20 m/s than in a motorbike travelling at the same speed.
Also the faster it goes the more kinetic energy the lorry will have.
A lorry moving at high speed will have much more kinetic energy than a lorry moving at low speed.
Therefore a fast moving car or lorry will cause more damage in an accident than a slow moving one because this kinetic energy has to be turned into other forms including sound, heat and stress on the other vehicles.
The kinetic energy of an object therefore depends on two things:
(a) the mass of the object (m)
(b) its speed (v)
The formula for kinetic energy of an object of mass m travelling at speed v is:
<span>Kinetic energy (k.e) = 練v<span>2</span></span>
Answer:
Adaptive radiation
Explanation:
Adaptive radiation occurs when an ancestral species move to a new environment that has various resources that are necessary for survival and also has environmental conditions that would ensure its offspring adapt well over time. In this new environment, the ancestral species would produce offspring with different traits and behaviors that will allow them to survive in this new environment while occupying their various niches. Over a relatively short time, different species arising from the common ancestor would occupy the new environment.
Assuming this is supposed to be a multiple choice question- I think the correct answer would be “early onset of spring change in marine ecosystems” because it looks like the question is asking what it wouldn’t affect, and I’m sure if the people had to leave, that animals would’ve all had to leave as well!

the birth rate on Earth is higher than the death rate
