What is the purpose of clamping a ruler in place during the Hookes law experiment?2 marksTo hang the spring in placeTo measure the length and extension of the spring accuratelyTo minimize the difference in measurementsTo record the mass in grams

The apparatus is to be set up for the candidates as shown in Fig. 1.1. The spring is to be suspendedfrom the clamp, supported by a boss and stand. The spring must be sufficiently high above thelaboratory bench so that when the 1.00 N load is suspended from the spring, the bottom of theload is above the surface of the bench.3. The metre rule (supported by the clamp, boss and stand) must be near to, but not touching, thespring. The 100 cm end of the metre rule must be touching the bench

How is the extension of the spring measured in the experiment?2 marksIn millimetersIn metersIn inchesIn centimeters

Which of the following should NOT be done when measuring the length of a rod using a ruler?a.place the zero-mark of the ruler on the middle of the rodb.place the ruler right beside the rodc.place the rod on a flat surfaced.record the measurement using your notebook or lab worksheet

When you put an object on a spring balance, what do you measure ?

Hooke's law describes a certain light spring of unstretched length 38.0 cm. When one end is attached to the top of a door frame and a 8.00-kg object is hung from the other end, the length of the spring is 41.0 cm.(a) Find its spring constant. kN/m(b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each with a force of 170 N. Find the length of the spring in this situation. cm
