Answer:
Meters
Explanation:"How FAR did the athlete run?"
Also it talked about meters
Answer:
the correct answer will be 6.82 %that is 7%
p(1.27)-q(0.83) =x=0.44
0.02+0.01 =0.03 (maximum uncertainty)
percentage uncertainty =0.03/0.44×100 %
=6.82%
=7%
Explanation: it was d on my end
suitcase can be pushed to a distance of 0.35 m
Explanation:
Work done= Ff d
w= 670 J
Ff= force of friction
d= distance
force of friction is given by Ff=μ mg
μ= coefficient of friction=2.76
m=mass=71.5 kg
so Ff= (2.76) (71.5) (9.8)
Ff=1934 N
so W= Ff d
670= 1934 d
d=0.35 m
