If the comb and the paper are attracted to each other the charge on the paper, is D)must be positive
<h3>
Laws of electrical attraction</h3>
This states that
- Like charges attract
- Unlike charges repel
Now, given that a negatively charged plastic comb is brought close to, but does not touch, a small piece of paper. If the comb and the paper are attracted to each other the charge on the paper, this implies that both the negatively charged plastic comb and the paper have opposite charges.
Since the charge on the plastic comb is negative, this means that the charge on the paper must be positive
So, if the comb and the paper are attracted to each other the charge on the paper, is D)must be positive

Answer:
-5.6m/s²
Explanation:
Given parameters:
Initial speed = 11.2m/s
Time of running = 2s
Unknown:
Acceleration of the puppy = ?
Solution:
Acceleration is the rate of change of velocity with time.
So;
Acceleration = 
final speed = 0m/s
Acceleration = 
= -5.6m/s²

Ok so you convert minutes to hours and multiply by 74 which gives 32.1km and the same goes for the 40 min which is 40/60 hours
and multiply that by 31 which is 21.7 km and for the 14 min it’s 14/60 times 27 which is 6.3 adding up all the kilometers gives you 32.1+21.7+6.3 and then you add all the minutes 26+40+14+12 which is 92 divide that by 60 and you get 1.53 hours and the km are 60.1, 60.1/1.53 gives us 39.3km/h.
