Abulb thermometer gives an indoor temperature reading of 21°c. a digital thermometer in the same room gives a reading of 20.7°c. which device is more precise? explain

Digital thermometer is more precise.

Explanation:

Digital thermometer is more precise because it is showing the temperature more precisely with 1 digit after decimal whereas the bulb temperature is measuring the temperature and giving the significant value.

Since the digital thermometer is measure temperature up to 1 digits of decimal, digital thermometer is more precise.

Digital thermometer is more precise

Explanation:

As we know that precise reading is that reading where we can measure upto more numbers after decimal

so let say a student A measure a mass of object as

m = 23.5 g

while other student B measure same mass as

m = 23.486 g

then here student A measure the mass one digit after decimal while student B measure mass 3 digits after decimal

so here student B is more precise than student A

similarly here digital thermometer measure the temperature as 1 digit after decimal so it is more precise

magnitude and direction

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
