Arrange the following sentences in their correct sequence (i) The total of standard weights gives the mass of the left pan (ii) Place the standard weights on the right pan. (iii) Hold the balance and ensure that there is nothing in the pan and the beam is horizontal. (iv) Place the body whose mass is to be measured on the left pan.
Can anyone tell the answer for this question , i will give you a thanks and mark you as the brainlist if you answer
Answers
Answer:
The physical balance or called as the beam balance was the first instrument which is used to measure the solid mass. It contains a pivoted horizontal lever having the same lengths of the arms. This is called as beam. It has two pans in which the standard weights and the solid substance is to be placed. The unknown mass is placed in the right pan and the standard pans are placed in the left pan, generally. We want to balance the beam so that the beam is completely horizontal. Now calculate the total mass of the standard weights and find out the mass of the unknown substance.
Precautions
i) The weights should be carried with forceps. They should not be carried with bare fingers to avoid the change in its weight due to the presence of moisture and dust particles.
ii) Wet and hot objects should not be kept on the pan.
iii) The beam should be lowered each time before adding or removing weights from the pan.
