Answer:


Δd = 
Explanation:
As
, when the car is making full stop,
.
. Therefore,

Apply the same formula above, with
and
, and the car is starting from 0 speed, we have

As
. After
, the car would have traveled a distance of

Hence 
As
we can simplify 
After t time, the train would have traveled a distance of 
Therefore, Δd would be 
Answer:
Motion with constant velocity of magnitude 1 m/s (uniform motion) for 4 seconds in a positive direction and then for 2 seconds uniform motion with constant velocity of magnitude 3 m/s in reverse direction .
Explanation:
The graph shows a constant velocity of 1 m/s for 4 seconds in the positive direction. After that, between 4 seconds and 6 seconds, the object reverses its motion with constant velocity of magnitude 3m/s.
Answer:
A: 3 Mg, 2 P, 14 O, 12 H
Explanation:
I took the test on Edgenuity
I will say increasing temperature but you dont have that option on your list, so I would take B. Increasing Concentration.
Answer:
The question is incomplete because the options are not given. We'll solve this question with the options.
There are two properties of negative charges which we have to consider to find the figure of its electrical field.
Firstly, for a negative charge, the electrical field lines are always directed radially outwards and they don't intersect.
Secondly, we know that similar charges repel each other, so there will be no electrical field present directly between these two negative charges. Electrical field line will be present between two charges only when there is a force of attraction.
Taking both of these facts into consideration, the electrical field line between two negatives is represented by the figure below.
