Answer:

The precautions to be followed for performing kirchoff law experiment are:-

check that all the connections inside the arrangement are tight and clean.
check that the terminals of the resistances are nicely attached.
ensure that the instruments used in the experiment set-up are indicating zero.(before starting of the experiment)

Explanation:

These are the basic precautions that must be kept in mind before executing kirchoff law experiment.

A force of 60 N is used to stretch two springs that are initially the same length. Spring A has a spring constant of 4 N/m, and

ad-work [718]

We can calculate the length of each spring by using the relationship:
$F=kx$
where
F is the force applied to the spring
k is the spring constant
x is the length of the spring (measured with respect to its rest position)

Re-arranging the equation, we have
$x= \frac{F}{k}$

The force applied to both spring is F=60 N. Spring A has spring constant of k=4 N/m, therefore its length with respect to its rest position is
$x_A= \frac{F}{k_A}= \frac{60 N}{4 N/m}=15 m$
Spring B has spring constant of k=5 N/m, so its length with respect to its rest position is
$x_B= \frac{F}{k}= \frac{60 N}{5 N/m}=12 m$

Therefore, the correct answer is
<span>D.Spring A is 3 m longer than spring B because 15 – 12 = 3.</span>
