Answer 1) : Change in direction.
Explanation : When an airplane starts to turn from south to west at constant speed gets accelerated due to change in direction. The change in direction of the airplane causes the airplane to accelerate in the direction of west while it was moving in south. Here the acceleration is being affected because of the change in direction of the object moving with a constant speed.
Answer 2) Change in direction and increasing speed.
Explanation : When a biker was riding at the speed of 5 m/s north and then changed the direction to west at an increased speed of 7 m/s this was due to increased speed and change in the direction of the bike.
There was two factors which contributed to change the acceleration in this case. It was because of change in speed of the bike and also because of change in direction. This kept the bike in acceleration by increasing the speed while changing the direction.
Answer 3) Increasing speed.
Explanation : While the shopping cart was observed to speed up on the runaway while it goes down a hill gets accelerated due to change in its speed.
In this case, when the shopping cart is been released from the upside runaway; as it goes down it gains more speed due to the slope of the runaway. This is because the acceleration is increasing because there is increase in the speed of the shopping cart.
The question is incomplete as it does not have the tiles which has been presented in the attachment.
Explanation:
Natural selection is the mechanism by which the species evolve. The species evolve under the influence of the natural pressure due to which the species try to hit and trial method of the adaptive trait. The trait which increases the fitness of a species is passed on to the next generation and the trait becomes established in a population.
This can be observed in the following scenario
1. The hawks predate on the rabbit species with white fur easily as they can be seen from the sky easily.
2. This acts as a pressure on the white rabbits as a result of which the white rabbits to hide themselves mutate and change the colour of the fur from white to brown or tan.
3. The founder effect will eliminate the white fur population from the whole population
4. The population with brown fur will increase with time and the trait will become a permanent trait.
Um they create a population of new food idk I hope this is it
What are the choices you just say which of the folowing
