Answer:
18.43m
Explanation:
At the initial stage, the car accelerates at 2.0 m/s² for 6.7 seconds, to get the velocity of the car at this point, we will use the equation of motion;
v = u + at
v = 0+(2.0)(6.7)
v = 13.4m/s
The velocity of the car during this time is 13.4m/s.
Also, if the car slows down at a rate of 1.5m/s², we can also calculate the time it took for the car to decelerate (check the attachment for diagram).
v = u+at
v = 0
u = 13.4m/s
a = -1.5m/s² (deceleration is negative acceleration)
0 = 13.4+-1,5t
-13.4 = -1.5t
t = 13.4/1.5
t = 8.93s
Hence it took the car 8.93s to slow down for the next stop sign.
To calculate how far apart the stop signs are, we need to calculate the total distance AD according to the diagram
Distance covered = AD = 18.43m
HENCE THE STOP SIGNS ARE 18.43m apart

Answer:
Maybe when you bump into the refrigerator and the magnet falls?
Explanation:
This is an example of you interacting with electromagnetics because you must have bumped into something and made a magnet fall.
I hope it helps?
If it does help can I have a brainliest?
Answer:
90 ohms
Explanation:
1/r = 1/180 + 1/180
1/r= 2/180
take the reciprocal of 2/180 which is 180/2 and its 90 ohms
