42. The circuit shown contains a resistor S that is neither in series nor in parallel with the Kirchhoffs laws can be used with the data in the diagram to deduce the resistance of each of the
two identical resistors labelled R.
What is the resistance of each resistor R?
a. 30
b. 4.00
c. 4.8
d. 5.00

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
