You are a drop of water going through the water cycle. Where doyou go?How do you get there? What processes do you go through?Include at least three phases of the water .
Answer:
If I were a drop of water and present in the ocean or any other aquatic system I should have moved in the water cycle as due to heats the water of the aquatic system such as the ocean becomes hot and evaporated turning into vapour, a gaseous phase of water.
Then vapour colloids with cooler air, and become cooler and convert into drops of water again which is called condensation. Drops of water again get back to the earth surface it can be in the form of rain, snow (ice form of water) termed as precipitation.
The three phases of the water cycle are
---> evaporation ---- > condensation -----> precipitation----

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
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
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.

An incline plane is 12-m long and 4-m high. A block is pulled up the ramp with a spring scale. The reading on the spring scale is 70-N. How many Newtons would the block actually weigh if you had to lift it the 4-m height?
Answer:
W = 210 N
Explanation:
For an ideal machine:
[tex]Work\ In = Work\ Out\\(P)(L)=(W)(H)[/tex]
where,
P = Effort = Spring Scale Reading = 70 N
L = Effort Arm = Length of inclined plane = 12 m
W = Actual Load (Weight) to be lifted = ?
H = Load Arm = Height = 4 m
Therefore,
[tex](70\ N)(12\ m) = (W)(4\ m)\\\\W = \frac{(70\ N)(12\ m)}{4\ m}[/tex]
W = 210 N

F = 16N
A beam of light from a laser pen passed through the air and then through a glass plate. Which diagram accurately models this phenomenon? Use evidence and scientific reasoning to defend your claim.
Explanation:
the second diagram depicts the phenomenon which is refraction and this stems from light moving from a medium to another......and in this case light moves from a less dense medium to a denser medium hence is refracted away from the normal(the straight line between the medium of air and glass)
PLS GIVE BRAINLY
Diagram B shows the refraction event and this is from light to medium, in this case, the light travels from a slightly narrower area to a compact area and is, therefore, further away from the normal (vertical line between the air and glass).
When a ray of light travels from a central location?When a ray of light travels from a dense area to a rare place, it bends away from normal.

The period of a wave is 20 ms (milliseconds) and its wavelength is 4 cm. Calculate:
a) The frequency of the wave
b) The velocity of the wave.
Answer:
A. 50 Hz
B. 2 m/s
Explanation:
We'll begin by converting 20 ms to s. This can be obtained as follow:
1000 ms = 1 s
Therefore,
20 ms = 20 ms × 1 s / 1000 ms
20 ms = 0.02 s
Next, we shall convert the value of the wavelength (i.e 4cm) to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
4 cm = 4 cm × 1 m / 100 cm
4 cm = 0.04 m
A. Determination of the frequency.
Period (T) = 0.02 s
Frequency (f) =?
f = 1 / T
f = 1 / 0.02
f = 50 Hz
Therefore, the frequency of the wave is 50 Hz
B. Determination of the velocity.
Wavelength (λ) = 0.04 m
Frequency (f) = 50 Hz
Velocity (v) =?
v = λf
V = 0.04 × 50
v = 2 m/s
Therefore, the velocity of the wave is 2 m/s

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