Question

the distance travelled by an object in time (100+-1)s is (5.2+-0.1)m what is the speed and its error​

Answer 1

Answer:

speed: 0.052m/s

error: 1.1

Explanation:

distance=5.2 with error 0.1

time=100 with error 1

speed=distance/time

speed=5.2/100===0.052m/s

error=1+0.1===1.1

bcoz error is always added.

=(0.052+-1.1)
