And that's your answer! :)
Answer: repeatable
Explanation: Accurate repeatable is needed in a valid experiment. I think
Shear stress created the San Andreas Fault in Southern California. It is an example of a <span>reverse fault.</span>
Answer:
Explanation:
A mass of 700 kg will exert a force of
700 x 9.8
= 6860 N.
Amount of compression x = 4 cm
= 4 x 10⁻² m
Force constant K = force of compression / compression
= 6860 / 4 x 10⁻²
= 1715 x 10² Nm⁻¹.
Let us take compression of r at any moment
Restoring force by spring
= k r
Force required to compress = kr
Let it is compressed by small length dr during which force will remain constant.
Work done
dW = Force x displacement
= -kr -dr
= kr dr
Work done to compress by length d
for it r ranges from 0 to -d
Integrating on both sides
W =
= [ kr²/2]₀^-4
= 1/2 kX16X10⁻⁴
= .5 x 1715 x 10² x 16 x 10⁻⁴
= 137.20 J
Answer:
The larger constant goes to the spring with the largest F/x ratio, this is by measuring a larger Force or by displacing less from the equilibrium position
Explanation:
Using Hooke's Law we have that for each spring the following relations is fulfilled:
Where F is the restoring force (opposite to displacement ergo the negative sign), k is the constant and x is the displacement.
All we need to do is to compare the following:
The larger constant goes to the spring with the largest F/x ratio, this is by measuring a larger Force or by displacing less from the equilibrium position
If you have numerical data we can run the calculations
