Answer:
a . 1/13
Step-by-step explanation:
Answer:

Step-by-step explanation:
you have that the average sped is given by the following formula:

The uncertainty formula for a division is given by:
(1)
Δv: uncertainty in speed
Δx: uncertainty in the distance = 0.9m
Δt: uncertainty in time = 0.7s
x: distance = 8.1m
t: time = 1.7s
You replace the values of all parameters in the equation (1):

Hence, the relation between the uncertainty in the average velocity is 0.426
Answer:
0,1
Step-by-step explanation:
x^2 − x = 0
Factor out an x
x(x-1) =0
Using the zero product property
x=0 x-1=0
Solving each equation
x=0 x-1+1 =0+1
x=0 x=1
The solutions are
x=0,1
the answer is none of the above because the variable cant be combined and 56 cant either.
