Acar speedometer has a 3% uncertainty. what is the range of possible speeds when it reads 70 km/h? a.) highest and lowest km/h b.)highest and lowest mi/h

(a) A 3 % uncertainty means a 3% uncertainty on the measured value.

The measured value is . The 3 % of this value is

So, the highest and lowest values are:

(b) To find the highest and lowest speeds in mi/h, we need to convert into these units. keeping in mind that

we have:

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the answer is b
