.. Investigate what are the derived quantities, then make a table where the relationships with the fundamental quantity to which

they belong.
Calculate the absolute and relative error in the following two cases:

• By measuring 4.7 m as the length of a room that is actually 4.67 m.

• By considering 51 m as the distance between two points actually located at 52.06 m

• As a measure of the radius of a 3 µm drop of saliva we have obtained 2.97 µm. Find the absolute and relative error.

• When measuring 2 m an error of 2 mm was made, and in 400 km the error made was

400 m. Which relative error is greater?

• The distance between Santiago and Santo Domingo is 155.56 km.

a) Approximate the distance to the tenths by rounding and truncation.

b) Calculate the absolute error made in both cases.

c) Calculate the relative error made in both cases.

d) Justify, according to the previous results, which approximation is better.

• When measuring a laboratory flask with an uncertainty range of ± 1 mm obtained as measurements of its base diameter 9.1 cm and height of 17.2 cm, determine the percentage of uncertainty of each of these measurements.



8. Determine the uncertainty in measurements.

1. What did you think of the content? Do you find it useful for life?


2. What did you feel or think while doing the activities?

3. What competencies did you reinforce through carrying out these activities? Justify your answer.

Earthquakes that originate beneath the ocean floor produce huge tidal waves called _____.
ololo11 [35]

Answer;

-Tsunami

Explanation;

-Tsunami  is a series of large ocean waves (or "wave train") of extremely long wavelength and period, usually generated when a gigantic body of water, such as an ocean, is suddenly displaced on a massive scale by an underwater disturbance such as an earthquake occurring on or near the sea floor or a volcanic eruption.

-After a sudden displacement of a large water volume by seismic activity (earthquake), the ocean floor is raised or dropped and large tsunami waves can be formed by gravitational forces.

Which characteristic is common to all permanent magnets?
yanalaym [24]

I can't eliminate answers. Some of them are just wrong.  A is incorrect. There is no such thing as a 1 pole magnet.

I wouldn't use B. If it is just a bar it is not a magnet.

C is the traditional answer

D is a space filler. It is just there to occupy a letter.

A runner completes the 300-meter dash in 38 seconds. What is the speed of the runner? Round your answer the answer to the neares
loris [4]

Answer:

speed = 7.9 m/s

Explanation:

speed = total distance / time taken

speed = 300 / 38

speed = 7.89473684 m/s

to the nearest tenth

speed = 7.9 m/s

A bucket filled woth water seems light while it sinks into water.Also show their relation using formula
slavikrds [6]

Answer: This phenomenon happens due to upthrust exerted by water.

Explanation:

We know that,

Liquid Pressure is directly proportional to the height of the vertical column in the liquid.(P∝h)

When a bucket filled water is sunk into the water container, there occur difference in the pressure in top and bottom of the water container. Due to this, water exerts an upward force on the bucket filled with water. This is called Uprthrust.

Upthrust on the bucket makes the bucket filled with water lose some of it's weight and causes apparent loss in weight.

Hence, the bucket filled with water seems light while it sinks into water.
