Answer 1

Two precautions that should be taken while doing the experiment of determining density of solid using a spring balance and measuring cylinder are:
1. Select a spring balance without zero error.
2. When an object is immersed in water, see that it does not touch the walls of the measuring cylinder.
3. while observing the readings of a liquid in measuring cylinder, always look at the lower meniscus of water level for readings.

Answer 2

The three simple precautions we taking here are

1,velocity

2,acceleration

3,displacement

4,distance

Are the four precautions
