An observer notices that 12 waves pass by in 4 seconds. What is the frequency of these waves? 0.33 Hz 16 Hz 48 Hz 3 Hz

Answers

Answer:

Frequency = 3 Hz

Explanation:

Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.

The frequency of these waves is 3 Hz. The correct option is D.

What is a frequency?

Frequency is the number of cycles or oscillations of a wave that occur in one second, measured in Hertz (Hz). It is a fundamental property of waves and is directly related to the energy and wavelength of the wave. The higher the frequency of a wave, the more energy it carries and the shorter its wavelength.

The formula for frequency (f) is:

f = 1 / T

where f is the frequency in Hertz (Hz) and T is the period of the wave in seconds (s). The period is the time it takes for one complete cycle or oscillation of the wave to occur.

Here in the Question,

The frequency of the waves can be calculated using the formula:

frequency = number of waves/time

In this case, the number of waves is 12 and the time is 4 seconds. Substituting these values into the formula, we get:

frequency = 12 waves / 4 seconds = 3 Hz

Therefore, the frequency of these waves is 3 Hz.

The current through a 12W resistor in an electric circuit is 1.5A. Calculate the potential differences across the resistor

Answers

Answer:

Potential difference = 8 Volts

Explanation:

Given the following data;

Power = 12 Watts

Current = 1.5 A

To find the potential difference;

Power = current * voltage

12 = 1.5 * voltage

Voltage = 12/1.5

Voltage = 8 Volts

Therefore, the potential difference which is the same as voltage is 8 Volts.

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells


Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?

In a certain circuit the number of electrons passing a given point in 3 seconds is 6 x 1014 electrons. What is the current flow in this circuit? (Show all work, including substitution with units)

Answers

Answer:

Current = 0.000032 Amperes

Explanation:

Given the following data;

Time, t = 3 seconds

Number of electrons = 6 * 10^14 electrons

Conversion:

First of all, we would convert the number of electrons to charge.

Coulombs = electron charge ÷ 6.2415 * 10^18

Coulombs = (6 * 10^14) ÷ (6.2415 * 10^18)

Coulombs = 0.000096 Coulombs

To find the current;

Mathematically, quantity of charge is given by the formula;

Quantity of charge, Q = current * time

Substituting into the formula, we have;

0.000096 = current * 3

[tex] Current = \frac {0.000096}{3} [/tex]

Current = 0.000032 Amperes

How does the intensity of light change for a location depending on the season?

Answers

Answer:

The intensity of light can change with the time of the day, season, geographic location, distance from the equator, and weather. It gradually increases from sunrise to the middle of the day and then gradually decreases toward sunset; it is high during summer, moderate in spring and fall, and low during winter time.

Explanation:

translational movement with the tilt of the earth's axis we can explain the change in intensity that an area receives determined with the weather station.

In summer the axis points to the sun, which is why more intensity per unit area arrives. In winter the axis moves away from the sun intensity per unit area is less

The intensity of the radiation is defined by the relationship between the power on the irradiated surface

        I = P / A

where I is the intensity, P is the power emitted by the sun and A is the area.

The intensity of the radiation that reaches it is around 1400 W / m² in the upper part of the Earth's atmosphere, this amount varies slightly when the planet passes from its furthest point from the sun to its closest point, that is, perihelion to aphelion.

The most important variation of this intensity is due to the fact that it has its axis inclined and the normal to the area changes in relation to the incident radiation during the translational movement around the sun.

In the summer the axis of the earth is inclined towards the sun, so the rays fall more perpendicularly, therefore their absorption over the area is maximum and the temperature rises.

In winter, the earth's axis is tilted away from the sun, so the rays they carry are distributed over a larger surface area and therefore less energy is absorbed per unit area and the temperature decreases.

In the spring and autumn seasons, the Earth's axis is almost vertical, so the absorption is intermediate and the temperature of the Earth is between the two maximums.

Using an analysis of the translational movement with the inclination of the earth's axis, we can explain the change in intensity received by an area determined with the weather station.

Based on the information in the graph, why is energy released during the fusion of hydrogen (H) into helium (He)?
A. The hydrogen-1 nuclei (H - 1) are more stable than the helium-4 (He - 4) nucleus is, because they have less binding energy per nucleon than the helium has.
B. There are fewer nucleons in a helium-4 (He-4) nucleus than there are in four hydrogen-1 (H - 1) nuclei, so there is more energy released per nucleon when helium forms.
C. The hydrogen (H) nuclei are lower in energy than the helium (He) nucleus is, so more energy is stored in a helium nucleus.
D. The helium (He) nucleus is more stable than the hydrogen (H) nuclei are, because more mass is converted into binding energy in helium.

The nearest star is a little more than ____ light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken _______________ to reach us. Light from the Sun takes ___________ to reach us.

Answers

Answer:

Because cosmic disaster are so vast, astronomers use light-years as their unit of distance. One light-year is defined as the distance a beam of light travels in one year. The nearest star is a little more than 4.37 light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken 2 million Earth years to reach us. Light from the Sun takes approximately 8.4269 minutes to reach us

Explanation:

i) One light-year is defined as the distance a light beam travels in a time of one Earth year. One light year is equivalent to 6 × 10¹² miles or 9.7 × 10¹² km

ii) The distance to the nearest star =  4.37 light-years

iii) When a star located in a galaxy that is 2.3 million light years away is seen, it has taken 2.3 million light years to reach us

iv) The distance of the Sun to the Earth = 151.58 million kilometers

The speed of light, c = 299792.458 km/s

The time it will take light to reach us from the Sun, 't', is given as follows;

t = 151.58 × 10⁶ km/(299792.458 km/s) ≈ 8.4269 minutes.
