Answer:
Her mistake was not multiplying both sides of the equation by 0.5
Step-by-step explanation:
The mistake is in Step 1--Tiffany was correct in multiplying the left side (h / 0.5) by 0.5 but made an error on the right side by dividing the 7 by 0.5 instead of multiplying.
<em>Thus, h= 3.5</em>
Answer:
A. x = 1/2at²
Step-by-step explanation:
Among the equations, the equation that is dimensionally consistent is x=1/2at² where;
x is the distance in meters (dimension is length (L))
a is the acceleration in m/s² (dimension is L/T²)
t is the time in seconds (s) (dimension of time is T)
Substituting the dimensions into the formula to check if we are going to arrive at the dimension for distance;
1/2at² = 1/2(L/T²)T²
= 1/2× L/T² × T²
= 1/2 × L
Since L which is the resulting dimension is the dimension for distance (x), this means that the equation x = 1/2at² is dimensionally consistent.
