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
<span>The flower width data were collected at about the same time
every day. </span>
According to the research, the responder made with the same
query as this question it is:
<span><span>
1.
</span>The flower width data were collected at about
the same time every day. </span>
Why this choice because, the study is delving into the
effects of morning temperatures on flower width hence, if the scientists
collect flower at the same time –hour or minutes everyday during the period of
the study the variable of time is not allotted from sunrise period to high noon
since it defines time as morning, the variant of time is only inapt.
Answer:
532.0725 m
102.17270893 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = g
H = Height of cliff
Distance traveled in 3 seconds
Distance traveled by sound = 2H-44.145 m
The height of the cliff is 532.0725 m
Her speed just before she hits the ground is 102.17270893 m/s
Answer:
B
Explanation:
The impulse experienced by an object is the force•time.
