(X+X)=x+9 what this mean is that when you get the answer you have to add it by nine
Step-by-step explanation:
a) unsuitable - the precision should have been about 0.030 kg (about an ounce)
b) unsuitable - the stopwatch should have a precision of 0.001 s
c) just about right, although I wouldn't mind it if its precision is of 0.05 mm
d) unsuitable - color matching requires much finer control so I would go with 1/8 cup precision.
we are given
A ball rolling down a hill was displaced 19.6 m
so,
the final velocity was 5.00m/s
so,
Since, a ball rolling down a hill was displaced
so, we get
we can use kinematic equation formula
Here ,
v is final velocity
u is initial velocity
a is acceleration
h is height from which ball is dropped
now, we can plug our values
................Answer
This is a false statement.
