Hey! Here's a a structure of a sample lab report:

<h2>Summary of Lab (SUBJECT)</h2>

Question(s) we are trying to answer:

Write question(s) here.

Add observations and/or previous experiments.

HYPOTHESIS

prediction
solution
replicable proposed solution
references (in)dependent variable(s)
etc

MATERIALS

Make a list of all materials used in the lab.

PROCEDURE

Write a detailed, step-by-step list (or paragraph in list format) that explains what you did in the lab.

It should be written so that somebody who's never done this can carry it out. Describe safety concerns.

It helps to have somebody test it out.

Results

Describe what happened!

Should include all data, tables, et cetera.

Label correctly!

Conclusion

Answer the following question:

Do my results support or oppose my hypothesis?

Explain why you chose what you did. Make sure it's UNBIASED.

Discuss errors.

Close out in the end.

The length of the mercury thread is found to be 4cm and 24cm at ice point and steam point respectively on an ungraduated thermom

BabaBlast [244]

Answer:

The difference between ice and steam in Celsius (Centigrade) is 100 deg.

So the difference between and 4 cm and 24 cm of the thread corresponds to 100 deg C.

So 8 cm is 4 cm greater than the ice point

4 cm / 20 cm = 1/5 since the steam point and the ice point are 20 cm apart

Then 1/5 * 100 deg C = 20 deg C the requested temperature

A little girl kicks a soccer ball. It goes 10 feet and comes back to her. How is this possible?

marta [7]

A classic puzzle...

She either kicked it at a wall exactly 10 foot in front of her, where the ball rebounded off the wall.

Or, she kicked the ball straight up, vertically, at a 90 degree angle, where due to the law of gravity, which states that anything that goes up must come down, when the soccer ball reaches exactly 10 feet, it falls back down.
(Note: This is nearly impossible to achieve -- exactly 10 feet.)

When reaching a boundary between two media (1 and 2), an incident ray is partially reflected and partially refracted. The ray is

lukranit [14]

Answer:

The angle of incidence when the reflected ray is perpendicular to the incident ray = 45°

Explanation:

According to Snell's Law,

n₁ sin θ₁ = n₂ sin θ₂

When the angle between the incident ray and reflected ray is 90°, the angle of incidence is θ₁ and the angle of reflection, θ₂ = 90° - θ₁ and the index of refraction in the Snell's Law for both media would be the same, n₁ = n₂ = n

n sin θ₁ = n sin (90° - θ₁)

Note that from trigonometric relations,

Sin (90° - θ₁) = cos θ₁

n sin θ₁ = n cos θ₁

(sin θ₁)/(cos θ₁) = 1

tan θ₁ = 1

θ₁ = arctan 1 = 45°

Hope this Helps!!!

Which of the following statements best explains why the table of known elements is called the "periodic table"? A. The table is

FromTheMoon [43]

It's called the periodic table because it arranges the elements the into repeating sets known as periods. this is defined by the covalence of an element and the number of electrons i has in its outermost shell. I feel the the Best answer would be B. sorry if im wrong but i hope i helped :)
