Answer:

0 m/s^2

Explanation:

Use a formula to answer the question

d = r * t

The object is not changing speed at any time, or if it is we are not told.  The rate is the speed.

8 = r * 1 second

8 m/sec = r

The initial speed is 8 and the final rate is 8. There is no change. So when you use this formula

a = (vf - vi)/t we get a = (8 - 8)/1 = 0

There is no acceleration because there is no change in speed.

The diagram does not represent a real electric field because the field lines, can someone help explain this for me
Papessa [141]

electric field lines are graphical presentation of electric field intensity

It is the graphical way to represent the electric field variation

If we draw the tangent to electric field line then it will give the direction of net electric field at that point

So whenever we draw the electric field lines of a charge distribution then it will always follow this basic properties

here we will always follow these basic properties of field lines

now as we can see that here two positive charges are placed nearby so the electric field must be like it can not intersect at any point because at intersection of two lines the direction of electric field not defined

As we have two directions of tangents at that point

So here the incorrect presentation is the intersection of two field lines which is not possible

Why are some fasteners double or triple threaded?
OLga [1]
<span>Fasteners are double or triple threaded with the idea of durability. People look for durability in a fastener and if they receive one with triple threaded or double threaded they will feel more safe and at ease knowing it has extra strength added.</span>

allochka39001 [22]
1. 2+0.5+2.5= 3. 2km/hr average




2. 14-6=4seconds. 8m/s in 4s = 2m/s acceleration


3. 15m/s divided by 2.5 = 6m/s acceleration
