If a measurement is 4.2 cm and its possible error is 0.04 cm, the relative error is?
1 answer:
Given the value of possible error, the relative error of the measurement is 0.0095.
Given the data in the question;
- Measurement taken;
- Absolute or possible erorr;
- Relative error;
Relative error is simply the ratio of the absolute or possible error of a measurement to the measurement its self.
Relative error is expressed as;
Where e is the absolute or possible error and m is the measurement being taken.
To determine the relative error, we substitute our given values into the expression above.
%
Therefore, given the possible error, the relative error of the measurement is 0.0095.

The apparent velocity is B) 48 m/s north
Explanation:
Here we have a problem of relativity of velocities.
In fact, the train is travelling north at a speed of
where this velocity is measured with respect to the ground.
At the same time, a passenger on the train is walking towards the rear (so, south) at a velocity of
where this velocity is measured with respect to the train, which is in motion in the opposite direction.
Therefore, the apparent velocity of the passenger with respect to an observer standing on the ground is:
And the direction is north, since this number is positive.
