One second.
Use the 2 second rule. Leave 2 seconds between your car and the car in front of you.
18 - 2 = 16
-3^2 = 9 -(3^2) = -9
The difference depends on the integers. If the first integer is greater than the second then difference is positive. If the first integer is less than the second then difference is negative. For example 6-4 = +2; 4-6 = -2
the difference is that on the first 9 it only has 1 mark on the second it has 2.
Yes, using either the 2-second rule or the 3-second rule means that as your driving speed increases, you leave more distance between you and the car ahead of you.
Difference between two numbers is found by subtracting the first from the second. Start with 5 apples, End with 7 apples. The difference is 2 apples.
If the difference in electronegativity between the elements is greater than 2 then the bond will be ionic, if its between 1.6 and 2 then it will be ionic if one of the elements is a metal.
-32 = -(32) = -9 (-3)2 = 9 The difference is 9 - (-9) = 18.
If difference is taken to mean the first number minus the second then the answer can be positive or negative (or zero if the two numbers are the same). For example: the difference between -5 and -3 is -2 while the difference between -3 and -5 is +2.
The 3 second rule (sometimes it's a 2 second rule) refers to the spacing a vehicle should maintain when following another vehicle, regardless of speed. The theory is that the faster the vehicles are traveling, the greater the margin of safety (spacing or distance) between the vehicles will be.
the difference is that on the first 9 it only has 1 mark on the second it has 2.
