Explanation:

The standard deviation is a measure of dispersion or variability of a data set. In order to determine the data set that has the smallest standard deviation, we shall investigate on the ranges of the data sets given. The range of a data set is simply the difference between the maximum and minimum values in a data set. A data set that has a smaller range also has a smaller standard deviation.

From the alternatives given, the data set given by alternative B has the smallest range and consequently the smallest standard deviation.

The maximum value is 23 while the minimum is 22. The range is 1.

The provided data is insufficient to calculate Daniela's velocity. This is because velocity not only considers the speed but also the direction. Therefore, information on Daniela's direction during the race is necessary for an accurate calculation.

Unfortunately, the question does not provide sufficient information to calculate Daniela's velocity. Velocity is a measure that describes how much distance an object covers in a particular direction in a given amount of time. To calculate this, we must know not just the speed (distance/time) but also the direction of travel. Without the necessary data regarding Daniela's direction of movement during her race, we cannot provide a precise velocity value.

Answer:

Period

Explanation:

we know that

The period of a wave is the time required for one complete cycle of the wave to pass by a point.

Period is the time which is taken by a wave to complete one complete cycle.

Explanation:

The period can also be referred as the time period or the wave period. The period is relevant to the concept of wave and its propagation, which leads to the measurement of its travel, leading to establish the relation between the period and the frequency.

The S. I. unit for the period is seconds. The period is in inverse relationship of proportionality with the frequency, which is the number of cycles completed in a second.

Answer:

U

Explanation:

The first law of thermodynamics states that:

[tex]\Delta U = Q-W[/tex]

where

U is the internal energy of the gas, which represents the sum of the chemical and thermal energy stored in the atoms and molecules of the gas

[tex]\Delta U[/tex] represents the variation of internal energy

Q is the heat absorbed by the system

W is the work done by the system

So, the sum of the chemical and thermal energy stored in atoms and molecules is represented by U, the internal energy.

wavelength

Explanation:

its expressed in meters

Final answer:

The property expressed in distance units is wavelength (option B), symbolized by λ, and typically measured in meters.

Explanation:

The property that is expressed in distance units is B. wavelength. It is the distance between two corresponding points of a wave, such as the distance between the midpoints of two consecutive peaks or troughs. The symbol for wavelength is λ (lowercase Greek lambda), and the units used to describe wavelengths are typically meters (m). Frequency, denoted by ν (lowercase Greek nu), is the number of oscillations that pass a specific point in a given period of time, measured in hertz (Hz). Speed, the rate at which a wave travels through a medium, is expressed in meters per second (m/s). Period, the time it takes for one complete oscillation to occur at a fixed point, is measured in seconds (s).

Answer:

[tex]49.7^{\circ}[/tex]

Explanation:

We can solve the problem by using Snell's law:

[tex]n_1 sin \theta_1 = n_2 sin \theta_2[/tex]

where

n1 = 1.33 is the index of refraction of the first medium (water)

n2 = 1.00 is the index of refraction of the second medium (air)

[tex]\theta_1 = 35^{\circ}[/tex] is the angle of incidence of the wave in water

[tex]\theta_2[/tex] is the angle of refraction of the wave in air

Solving for the angle of refraction,

[tex]sin \theta_2 = \frac{n_1 sin \theta_1}{n_2}=\frac{(1.33) sin 35^{\circ}}{1.00}=0.763\\\theta_2 = sin^{-1} (0.763)=49.7^{\circ}[/tex]

Explanation:

the answer is A

metallic bonds are formed between metal ions

Answer:

Their atoms have identical mass.

Explanation:

Oxygen-17 and Oxygen-18 are both isotopes of Oxygen.

Oxygen has three isotopes, Oxygen- 16, Oxygen-17 and Oxygen-18.

Oxygen- 16 has 8 protons and 8 neutrons and a mass number of 16.

Oxygen-17 has 8 protons and 9 neutrons and a mass number of 17.

Oxygen-18 has 8 protons and 10 protons and a mass number of 18.

The three isotopes therefore have the same atomic number ( the number of protons) but different mass numbers.

At the instant the second bulb is connected ...

... the brightness of the first bulb doesn't change

... the brightness of the second bulb changes from dark (no brightness) to equal to the first bulb

When the second 20 Ohm bulb is added in parallel, the bulbs becomes brighter

Adding a second, identical 20 Ohm bulb in parallel with the first one will have the effect of increasing the brightness of the bulbs.

In a series circuit, the total resistance increases as more resistors are added, which reduces the current flowing through the circuit. As a result, the bulbs would be dimmer in a series circuit.

However, when the second 20 Ohm bulb is added in parallel, the total resistance decreases, allowing more current to flow through the circuit. This increased current results in a higher brightness of the bulbs.

Refraction is the bending of light as it passes from one medium to another, causing objects to appear shifted or distorted when viewed through lenses.

The wave interaction that occurs as light passes from the air into the plastic lenses of the sunglasses is refraction. Refraction is the bending of light as it passes from one medium to another due to the change in its speed. This bending of light is what makes objects appear shifted or distorted when viewed through lenses.

Answer:

5.5 m/s

Explanation:

Assuming the bottle is initially stationary, we can write the law of conservation of momentum as follows:

[tex]p_i = p_f\\m_b u_b = m_b v_b + m_B v_B[/tex]

where

[tex]m_b = 0.4 kg[/tex] is the mass of the ball

[tex]u_b = 18 m/s[/tex] is the initial velocity of the ball

[tex]m_B = 0.2 kg[/tex] is the mass of the bottle

[tex]v_B = 25 m/s[/tex] is the final velocity of the bottle

[tex]v_b[/tex] is the final velocity of the ball

Solving for [tex]v_b[/tex],

[tex]v_b = \frac{m_b u_b - m_B v_B}{m_b}=\frac{(0.4 kg)(18 m/s)-(0.2 kg)(25 m/s)}{0.4 kg}=5.5 m/s[/tex]

The answer is:

The voltage of the source is 8.40 Volts.

To solve the problem, we need to use the Ohm's Law equation, which states that:

[tex]Voltage(Volts)=Current(Amps)*Resistance(Ohm)[/tex]

From the statement we know that:

[tex]Resistance=2.21\Omega\\Power=32W\\Current=3.8A[/tex]

Now, substituting and calculating we have:

[tex]Voltage(Volts)=Current(Amps)*Resistance(Ohm)[/tex]

[tex]Voltage(Volts)=3.8A*2.21\Omega=8.40V[/tex]

Hence, we have that the voltage of the source is 8.40 Volts.

Answer:

Redshift increases with distance

Explanation:

Edwin Hubble discovered a relation for distance and radial velocities of galactic nebulae from their redshifts i.e., when an object is moving away from earth the wavelength of light gets changed due to the Doppler effect.

He also found that two galaxies when further apart have a greater speed by which they are moving away from each other. This was used to prove the Big Bang theory laid down by Georges Lemaître.

Answer:

False

Explanation:

No. The buoyant force on an object is the portion of its weight that appears to vanish

when the object is in any fluid (could be either a liquid or a gas).

If the object happens to float in a particular fluid, then the buoyant force at that moment

is equal to the object's weight.

Notice that the buoyant force on an object will be different in different fluids.
