2. To determine the density of solid by using a spring balance and a measuring cylinder.
please give me ans of this two question
u can also give answer throgh google also
please please please

Answer:
To establish relationship between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance. 1. According to third law of motion, for every action, there is an equal and opposite reaction
Explanation:
Tie a metal bob (or any solid) with the string of cotton to the hook of the spring balance. The spring balance should be checked for any error. Let the zero error be 'x'.
Hold the spring balance (or tie it to the stand), suspended with the metal bob in air. Measure the weight of the bob. Let its weight be ‘WF'
Pour the water in the measuring cylinder and record the initial volume of water, let it be ‘ V1'
Suspend the metal bob into the measuring cylinder with water. The bob should not touch the base, nor the sides of the cylinder.
The water level rises, measure the increased water level, let this volume be ‘ VF'
Record all your observations in the observation table and do the calculation to find the density of a given solid metal bob.
Precautions
The spring balance should be sensitive.
The zero error in the spring balance should be recorded before it is used to find the weight of solid.
Record the readings carefully of both spring balance and measuring cylinder by keeping the level of eye and the mark of reading same/parallel.
The solid/metal bob should not touch the bottom, or sides of the measuring cylinder.
If the zero error in spring balance is 1 N then subtract this error from the final reading of the weight of solid/ metal bob.
