Answer:
Distance, S = 13m
Explanation:
Given the following data;
Initial velocity, u = 4m/s
Final velocity, v = 9m/s
Time, t = 2 seconds
To find the distance, S;
First of all, we would determine the acceleration of the shark.
Acceleration = (v - u)/t
Acceleration = (9 - 4)/2
Acceleration = 5/2
Acceleration = 2.5m/s²
Now, to find the distance we would use the second equation of motion
S = ut + ½at²
Substituting into the equation, we have
S = 4(2) + ½*2.5*2²
S = 8 + 1.25*4
S = 8 + 5
Distance, S = 13m
I have a strong hunch that if you read through pages 184 to 187 in the book,
you'll find each of these statements there, with no blank spaces.
1. negative
2. static
3. electrons
4. repel
5. attract
6. static
7. electric current
8. closed or complete
9. open

Hi! :)
Which of these statements best explains why models are used to study atoms?
Atoms are too small to be examined in detail without a microscope!
Models help scientists to study atoms because atoms are extremely small and can't even be seen!

Answer:
Explanation:
At the bottom the tension would be upwards and the weight downwards, their difference being the centripetal force. Taking the upwards direction as positive we then have:
where we have used the equation for centripetal acceleration. Thus we have:
