<span>1 hour 36 minutes = 1 36/60 = 1 3/5 = 1.6 hours
Speed of car leaving wallace be x mph
Speed of car leaving vernonville will be ( x+10) mph
1.6 ( x + x+10) = 192
2x + 10 = 120
2x = 110
x = 55
ANSWER Wallace car = 55 mph Vernonville = 65mph
Therefore, </span><span>the average speeds of both cars are 55 mph for the Wallace car and 65 mph for the Vernonville.

Answer:
The value of Q is - 8 C
Explanation:
Given;
the magnitude of first charge = 2 C
position of the first charge = 0
_ (2m) 0(+2C) +(2m)(Q)
------------------------------------------------------------------------------------
E₁ --------------------------------->
<------------------------------------------------------------------ E₂
E₁ and E₂ are equal in magnitude but opposite in direction
| E₂ | = | E₁ |

Thus, since E₂ is opposite in direction to E₁, the Q = - 8 C
D, because the hairdryer uses a fan
E, because it produces heat
Their atomic numbers are all the same, because they all have the same number of protons. But their atomic weights are different, because they have different numbers of neutrons.
