Answer: When you turn a light on it becomes bright :)

In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in flashlights, vehicles, and other devices.

Answer:

1.8 cm

Explanation:

To measure length, use a metric ruler. It is separated into centimeter-sized units. One centimeter is represented by each number on the ruler. The longest mark is the centimeter.

A metric scale is used to quantify traits or variables. Interval scales, ratio scales, and absolute scales are all grouped under the phrase “metric scale.”

The majority of statistical calculations and comparisons are possible with quantitative numerical values.

To the nearest tenth of a centimeter (0.1 cm), a metric ruler, for instance, may measure length. Using a separate metric ruler, you can measure lengths to the nearest 0.05 centimeters (0.05 cm).

The measurement with the lowest degree of uncertainty (0.05 cm) is more accurate.

Therefore, 1.8 cm is the length of the blue line in centimeters.

Answer:

Answer:

Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

The atomic size of an element significantly depends on the number of protons. It is the characteristic property of isotopes that they possess the same number of protons which is responsible for the same atomic size.

Isotopes may be defined as one of two or more species of atoms of a chemical element that have the same atomic number and location in the modern periodic table with identical chemical behavior but with different atomic masses and physical properties.

In a more simple sense, isotopes are those elements that have the same atomic number but different atomic mass. The atomic number depends on the number of protons which remains constant in isotopes. So, the isotopic elements have identical atomic sizes.

Therefore, the isotopes of the same element have the same atomic size.

Answer:

Yes, acetaminophen is conductive in water.

Explanation:

Have a nice day!

Acetaminophen is conductive in water and it is electrochemically active. It is used as an antipyretic drug.

Acetaminophen is an organic compound containing the amine functional group. One of the most popularly prescribed analgesic and antipyretic medications, acetaminophen (AC), is thought to be both effective and safe.

AC is not poisonous or harmful when used rationally, but an overdose or continued use may cause nephrotoxicity and severe hepatotoxicity. As a result, AC monitoring is crucial for drug safety.

Various conductometric measurements reported the fair conductivity shown by acetaminophen in water. The intermolecular interaction of acetaminophen in water make it conductive.

Answer:

frequency

Explanation:

The number of wavelengths that pass through a fixed point in a second is called the frequency of the wave. It has the unit of Hertz. Hence, option C is correct.

The term that refers to the number of wavelengths that pass a fixed point in a second is frequency.

Frequency is a fundamental concept in wave motion and is defined as the number of complete cycles of a wave that occur per unit time. For example, the frequency of a sound wave is measured in hertz (Hz) and is equal to the number of sound wave cycles that occur per second.

The higher the frequency of a wave, the more cycles occur in a given period of time. Wavelength, on the other hand, refers to the distance between two adjacent points on a wave that are in phase with each other, such as the distance between two crests or two troughs.

Wavelength and frequency are related, and the frequency of a wave is inversely proportional to its wavelength. As the frequency of a wave increases, its wavelength decreases.

Amplitude refers to the maximum displacement of a wave from its equilibrium position, while compression is a region in a longitudinal wave where the particles are close together. Hence, option C is correct.

Sodium-24 has a half-life of approximately 15 hours. If only one-eighth of the sodium-24 remain , then it has been passed in 60 hours. So option D is correct.

The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T₁ ÷ 2, and the decay constant is given by T₁/2 = 0.693/λ

According to radioactive decay law, the rate of decay of radioactive atoms at any instant is directly proportional to the number of atoms present at that instant.

dtd N ∝ N

dtd N = λ N

where, N is number of integrated nucleus present in the sample at any time t and λ is decay constant.

Thus ,option D 60 hours is correct.

According to the forces of attraction, boiling takes place when the kinetic energy of molecules overcomes the intermolecular forces.

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.
