How should measurement of car 2 be taken to accurately measure the distance it travels? Be sure to include where the meter stick should be placed.

the experimental setup, with car 1 is at the top of a ramp and car 2 at the bottom of the ramp

car 1
/ ←top of ramp
/ ←bottom of ramp
car 2

Answers

Answer 1

answer

The meter stick should be placed at the starting position of car 2 at the base of the ramp so that it measures the part of car 2 that will end up the furthest away from the base of the ramp.

explanation

i dont know if this is right or not but my teacher gave me a 90 so there is a 50/50 chance its right or wrong

What are some of the regulations about cell phone waste?


Are the regulations the same everywhere, which countries have different regulations?


New technology to reduce waste?


Pls and thank you!

Answers

What are some of the regulations about cell phone waste?

In general, companies take part in the responsibility of taking back the e-waste resulted from their products.

Are the regulations the same everywhere, which countries have different regulations?

In 2005, two important directives were published in the European Union. The first stipulates that: 1) all manufacturers selling electrical and electronic equipment in and to EU countries label the equipment to inform customers that it must be recycled and 2) make sure that their products are properly disposed of or recycled after the life cycle. The second requires manufacturers to eliminate or minimize the use of lead, mercury, hexavalent chromium, cadmium, polychrome and diphelin biphenyl ethers in electrical and electronic equipment sold in the EU after 1 July 2006.

New technology to reduce waste?

Companies are trying to reduce the amount of resources needed in order to create their products. One alternative is the modular smarthphones, which aims to reduce the amount of e-waste of the phone by only upgrading a few elements of hardware.

Contains elements carbon, hydrogen and oxygen, the empirical formula of butanedion is C2H3O and its molar mass is 86.09% find its empirical formula

Answers

Answer:

Molecular formula = C₄H₆O₂

Explanation:

Given data:

Empirical formula of butanedion = C₂H₃O

Molar mass of  butanedion = 86.09 g/mol

Molecular formula  butanedion = ?

Solution:

Formula:

Molecular formula = n(empirical formula)

n = molar mass of compound / empirical formula mass

empirical formula mass  = 2×12 +1.008×3 +1×16 = 43.024

n = 86.09 / 43.024

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₃O)

Molecular formula = C₄H₆O₂

A substance has an atomic number of 80 and a mass number of 178. How many protons does this atom have? How many neutrons does it have? How did you determine this? Write your answer in ACES format.

Answer:

Cite (source and evidence):

Explain:

Summarize:

Answers

Answer:

This atom has 80 protons and 98 neutrons.

Explanation:

All atoms are composed of a central nucleus in which there are positively charged particles, the protons, and neutrally charged particles, the neutrons, around which other negatively charged particles, called electrons, move.

The atomic number, identified with the letter Z, indicates the number of protons that are present in the nucleus of an atom. The atomic number defines the electronic configuration of the atom and allows the ordering of the different chemical elements in the periodic table.

If a substance has an atomic number of 80, this atom has 80 protons.

The mass number indicates the total number of particles in the nucleus, that is, the sum of protons and neutrons.

mass number = number of protons + number of neutrons

In this case you know that the mass number is 178 and number of protons is 80. Then

number of neutrons=mass number - number of protons

number of neutrons= 98

So this atom has 98 neutrons.

3.6 x 10-6 in standard notation.

Answers

Answer: 0.000036

Explanation:The standard form is just the normal method of depicting a number. To get from scientific notation to standard form, you would multiply the number from the scientific notation by the increasing / decreasing factor (10n). When the factor decreases, the 10 is raised to a negative power and the decimal moves to the left n amount of times (example the

10−5 moves your decimal in 3.6 over to the left 5 times leaving you with 0.000036). The opposite is true for increasing factors.

3.6 x 10⁻⁶ in standard notation is 0.0000036.

Standard notation refers to the conventional symbols, terms, and formats used to represent mathematical, musical, scientific, or other technical concepts.

Scientific notation is a way to express very large or very small numbers using powers of 10. It is commonly used in scientific and mathematical calculations to represent numbers that are too big or too small to be conveniently written in standard decimal notation.

To convert a number in scientific notation to standard notation, multiply the coefficient by the power of 10.

In 3.6 x 10⁻⁶, the coefficient is 3.6 and the exponent is -6.

To convert it to standard notation:

3.6 x 10⁻⁶  = 0.0000036

3. One example of condensation is dew forming on grass or leaves early in the morning when the air is cooled/cooling.

4. This is called freezing. For example, when water turns into ice (a solid) because it freezes.

5. This is called melting. The butter reached its melting point and turned into a liquid.

6. Adding or removing energy causes changes in states of matter. Temperature for example can cause melting and freezing.

7. Water which collects as droplets on a cold surface when humid air is in contact with it.

8. Evaporation/vaporization

9. before- particles are compact

during- particles vibrate

after- the particles move freely

10. condensation because it is going from gas into a liquid

11. Evaporation, I know because when liquid gets heated after a period of time  and it reaches its boiling point, it will begin evaporating.

12. When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

13. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.

14. freezing because particles are becoming compact and getting slower because of decrease in temperature

15. Examples are mothballs, dry ice, snow in the winter months, freeze-drying (ice crystals in a frozen food bag), air fresheners, and printers that print out high-resolution images.

16. Try and think of it in terms of the molecules. The temperature is such that the molecules are all bound together into a solid. Occasionally a surface molecule picks up enough energy to break it bond,.. a statistical probability ,and drifts away. The overall temperature of the solid is reduced by that event,as temperature is just an average of the energy. A little more heat flows into the material ,from the ambient environment, and another molecule escapes, and so the process continues….. if the concentration of the molecules in the vapour space above the solid, is low the reverse process of molecules condensing onto the surface,and releasing energy back into the solid is low.
