Answer:
a) One-ninth the force acting on object A.
Explanation:
First, we derive an expression for the centripetal force acting on both objects.
For object A, centripetal force is:
For object B, centripetal force is:
We are given that they have the same mass and they move in circles of the same radius.
If object A completes three times as many rotations as object B, then, object must have 3 times the speed of object B.
Hence:
Therefore, becomes:
=>
Therefore, the net centripetal force acting on object B is one-ninth of the force acting on object A.
Answer:
y = 1.06 x + 0.14
r² = 0.95
Explanation:
a) To make this graph, a spreadsheet-type calculation program is used, see attached.
On the y axis are the measured values
On the x-axis, the values checked in the experiment are placed.
From the graph we see that a linear graph and that one of the values has a strong deviation with respect to the others
b) The red line is the best straight line that can be drawn,
for this the quality ajust is r²
the closer to 1 the better the fit
the equation of the line is
y = 1.06 x + 0.14
r² = 0.95
