Question for anyone who is amazing in writing lab reports
What is required to write a good conclusion. It seems that my conclusions are my only flaws when writing lab reports and get points off because of it. Can you please post a photo of a conclusion of a past lab report so that I can get a better idea.

Thank you for the help. Please don't answer anything unrelated. :)

Answer:

Distancia = 50.04 metros

Explanation:

Dados los siguientes datos;

Velocidad = 10 km/h

Tiempo = 18 segundos

Para encontrar la distancia;

Conversión:

10 km/h = 10 * 1000/3600 = 2.78 m/s

Distancia = velocidad * tiempo

Distancia = 2.78 * 18

Distancia = 50.04 metros

Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.

Answer:

yes

Explanation:

yes

Answer:

Fc = 4340,93 Newton

Explanation:

Dados los siguientes datos;

Masa = 900 kg

Velocidad, V = 50 km/h a metros por segundo = (50 * 1000)/(60 * 60) = 50000/3600 = 13,89 m/s

Radio, r = 40 m

Para encontrar la fuerza centrípeta;

Fc = mv² / r

Fc = (900 * 13,89²)/40

Fc = (900 * 192,93)/40

Fc = 173637/40

Fc = 4340,93 Newton

Answer:the specific heat is the measure of how much heat per unfit mass required to raise the temperature by 1 degrees Celsius.the formula is given as Q= cm T where

Q= the amount of heat added

C= specific heat of a substance

T= change in temperature in degrees Celsius

Q=(4186 j/kg degrees Celsius (.109 kg) (8.93- degrees Celsius)=4974.53J

Explanation:

The mass of the copper coin placed in 101g of water is 135.3g.

The mass of the copper coin can be calculated using the following expression:

Since; Q = mc∆T

Where;

mc∆T (water) = mc∆T (copper)

According to this question;

COPPER METAL:

WATER:

101 × 4.18 × 8.39 = (0.385 × m × 68)

3542.09 = 26.18m

m = 3542.09 ÷ 26.18

m = 135.3g

Therefore, the mass of the copper coin placed in 101g of water is 135.3g.

Answer:

9)  HIGHER  AND LOWER INTESITY, 10) speed of sound must decrease.

11) guitar the strings, flute,  12) In the mountains,  13) sound of a low frequency horn (sub-wofeer)

Explanation:

In this exercise we are asked to complete the sentences.

9) the intensity of the sound is the square of the amplitude, the missing words are

      HIGHER INTESITY

      LOWER INTENSITY

10) the speed of sound is

          v = [tex]\sqrt{\frac{B}{\rho} }[/tex]

and it is also related to temperature

         v = [tex]v_o \sqrt{1+ \frac{T}{273} }[/tex]

We must be careful since the compressibility modulus (B) changes significantly between the solid, liquid and gaseous states, if we are in the same medium, the speed of sound decreases with increasing density. For a higher density the speed of sound decreases

Also the speed of sound increases with temperature, but its effect is less,

Therefore, by having these two effects in the opposite direction, the change in density is more important, so the speed of sound must decrease.

.

11) when you listen to a guitar the strings resonate with the instrument body

   on the flute has a resonance between the blown air and the flute tube

12) When you are in front of a tall object, the sound is reflected and the echo is heard.

      In the mountains, in the squares where there is a large object that reflects in sound

13) when we hear the sound of a low frequency horn (sub-wofeer) we feel the vibration of the air, this is an effect of the pressure energy of the sound on our chest

Explanation:

Answer:

50,000

Explanation:

when we say significant digits we mean the numbers that matter when stating the value of the number.

0.00030 can be written as 0.0003 without affecting it's value, the last zero is not significant.

50,000 all of the numbers here are significant to its value if we take away a zero it becomes 5,000 which is not equal to 50,000. so every digit here is significant

100.0300 can be written as 100.03 without loosing any value

500.00 can be written as 500 without loosing any value. ( think of this as $500.00, this also equals $500)

Answer:

Use the drop-down menus to identify the parts of the diagram labeled A, B, and C.

Label A

✔ battery

Label B

✔ light or bulb

Label C

✔ switch

Explanation:

The parts A, B and C are battery, light bulb and switch respectively.

The electrical circuits are defined as the closed-loop or routes that create a web of electrical components through which electrons can move.

Here,

The given diagram is of an electric circuit.

Wires are used to construct this path, which is powered by a battery or another energy source.

Part A

The beginning of the point where electrons begin to flow is referred to as the source, known as the battery and the end of the point where electrons leave the electrical circuit is referred to as the return.

Part B

An electrically powered light bulb is a type of lighting source. By passing current through a small wire called a filament, light bulbs convert electricity into light. Tungsten is a substance that produces light when electricity is delivered through it, and this is often the material used to make the filament.

Part C

It is the switch. An electrical circuit can be broken by a switch by rerouting current from one conductor to another conductor or an insulator.

Hence,

The parts A, B and C are battery, light bulb and switch respectively.

Answer:

9.0 m

Explanation:

Applying

V = kq/r......................... Equation 1

Where V = Electric potential, q = charge, r = distance, k = Coulomb's constant.

make r the subject of the equation

r = kq/V................... Equation 2

From the question,

Given: q = 1.00×10⁻⁵ C, V = 10000 V

Constant: k = 9.0×10⁹ N⋅m²/C²

Substitute these values into equation 2

r = (9.0×10⁹×1.00×10⁻⁵)/10000

r = 9.0 m

Height of the building = 35.78 m

Explanation:

Given that,

The time period of a pendulum is, T = 12 s

We need to find the height of the building. The formula for the time period of a pendulum is given by :

[tex]T=2\pi \sqrt{\dfrac{l}{g}}[/tex]

Where

l is the height of the building

[tex]l=\dfrac{T^2g}{4\pi^2}\\\\l=\dfrac{(12)^2\times 9.8}{4\times 3.14^2}\\\\l=35.78\ m[/tex]

So, the height of the building is 35.78 m.

Answer:

Explanation:

The light reflects off a rough surface, what happens to the image is that will occurs No image is formed.

Reflection of light happens when a ray of light strikes a reflective surface and returns to its original medium. This phenomenon allows us to see all bodies that do not produce their own light, called secondary sources of light or simply illuminated bodies.

Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

Answer: [tex]30.09\times 10^{-15}\ C[/tex]

Explanation:

Given

The first charge is [tex]q_1=-6\ C[/tex]
