In a free fall experimate you determine the value of acceleration due to gravity (g) to be 9.50 m/s2 . The accepted value is 9.8
1 m/s2 . What your percent error?
1 answer:
If the value 9.81 is correct, then your error is (-0.31).
As a fraction of the correct value, your error is (-0.31)/(9.81) .
That's -0.0316, or -3.16 percent .
By the way ... LAST time somebody posted this same question on Brainly, he was nice enough to also let us see the list of choices.

Answer:
1.55 N
Explanation:
Density = mass / volume
0.789 g/mL = m / 200.0 mL
m = 157.8 g
Weight = mass × acceleration due to gravity
W = (0.1578 kg) (9.8 m/s²)
W = 1.55 N
Answer:
wave length is 1.2m
Explanation:
since formula of wave length is v/f
v(speed of sound in air at stp is 300ms^-1)
f(frequency 250hertz)
then wave length is 300÷250 which give 1.2m
