C did the most effort, but A walked the longest, so a reasonable answer is that they all did the same amount of work, as B simply mediates.
Answer:
1 kg
Explanation:
Applying,
Hook's law,
F = ke................. Equation 1
Where F = force, k = force constant of the spring, e = extension.
But from the question,
The weight of the bottle is the force acting on the spring scale
therefore,
mg = ke............ Equation 2
Where m = mass of the bottle, g = acceleration due to gravity.
make k the subject of the equation
k = mg/e............ Equation 3
Given: m = 0.5 kg, e = 1 cm = 0.01 m
Constant: g = 9.8 m/s²
k = (0.5×9.8)/0.01
k = 490 N/m
If the mass of the second bottle is weighed,
given: e = 2 cm = 0.02 m
subtitute into equation 1
m×9.8 = 490×0.02
9.8m = 9.8
m = 9.8/9.8
m = 1 kg.
Hence the mass of the second bottle is 1 kg
Answer:
Please find the answer in the explanation
Explanation:
Given that Force affects the body and results in different changes.
The grid that has the words related to the effects of force are :
a) Force could be a push or a pull.
c) Force has magnitude as well as direction.
e) Force acting on an object may cause a change in its state of motion or a change in its shape.
f) A force can act on an object with or without being in contact with it.
