describe atmospheric pressure and water pressure
Answer:
The difference is that water is an incompressible fluid — its density is almost constant as the pressure changes — while air is a compressible fluid — its density changes with pressure. ... Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid) above it

An entertainer pulls a table cloth off a table leaving behind the plates and sliverware undisturbed is an example of
A.
the law of balanced forces
B.
Newton's second law
C.
Newton's third law
D.
Newton's first law
Answer:
D. Newton's first law
Explanation:
Newton's first law of inertia says that an object will remain how it is, unless affected by an outside force. In this case, the plates want to remain stationary(not moving). Therefore, if you pull the table cloth fast enough, the force of friction produced will be small enough so that the Inertia of the plates will overcome the force of friction.

Calculate the speed of a periodic wave that has a wavelength of 2.0 m and a frequency of 3.0 Hz.
Answer:
v=wavelength x f = 2 x 3 = 6 m/s
Explanation:
The speed of a wave is the product of its frequency and wavelength. The speed of the periodic wave with the frequency of 3 Hz and wavelength of 2 m is 6 m/s.
What is frequency?Frequency of a wave is the number of wave cycles per unit time. It is the inverse of the time period of the wave. Frequency is inversely proportional to the wavelength of the wave.
The relation between speed, frequency and wavelength of a wave is given by the expression as written below:
c =νλ
where, c is the speed, ν be the frequency and λ be the wavelength.
Given that ν = 3 Hz or 3 s⁻¹
and λ = 2 m
then speed c = 2 m × 3 Hz = 6 m/s
Therefore, the speed of the periodic wave is 6 m/s.

hurricanes, flooding, wave surge
earthquakes, tsunami, landslides
blizzards, freezing conditions, snow drifts
Transform plate tectonic boundaries slide/move past each other, rubbing along the edges causing earthquakes, tsunami, landslides
What is earthquake?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
The answer is c is because when tectonic plates are rubbing against each other that’s how an earthquake is formed.
another reason the answer is C is because when the tectonic plates are moving together it can cause the land to slide.
the last reason the answer is C is because when the tectonic plates in the ocean move it can cause a tsunami.

What is electric charge ?Electric charge is the physical property of matter that experiences force when it is placed in electric field. F = qE where q is amount of charge, E = electric field and F = is force experienced by the charge. there are two types of charges, positive charge and negative charge which are generally carried by proton and electron resp. like charges repel each other and unlike charges attract each other. the flow charges is called as current. Elementary charge is amount of charge a electron is having, whose value is 1.602 x 10⁻¹⁹ C
Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.
Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform. There are two types of the wave longitudinal wave and transverse wave.
Frequency is nothing but the number of oscillation in a unit time.
Given,
frequency f = 60.0 Hz.
time t = 1.0 h = 60*60 = 3600s
F = number of cycles/time
number of cycles = F×time
The number of cycles in 1 Hr is
60*3600 = 2.2×10⁵ cycles.

answer is A:14
Explanation:
The temperature of the thermometer which reads 57 °F in degree celsius (°C) to the nearest whole number is 14 °C
Conversion formulaWe can convert from degree celsius (°C) to degree Fahrenheit (°F) with the following equation
°C = 5/9(°F – 32)
How to determine the temperature in degree celsius (°C) Temperature (°F) = 57 °FTemperature (°C) =?°C = 5/9(°F – 32)
°C = 5/9(57 – 32)
°C = 5/9 × 25
°C = 14 °C
Thus, the temperature in degree celsius (°C) of the thermometer is 14 °C

Answer:
A plane of symmetry that forms mirror images around a vertical plane in the midline.
Explanation:
Bilateria are animals that have a bilateral symmetry,
Bilateral symmetry refers to organisms that are mirror images along their midline called a sagittal plane.
Examples of bilateria include butterflies and humans because, a line through their midline divides the organism into two identical halves which are mirror images of each other.
So, Bilateria are characterized by a plane of symmetry that forms mirror images around a vertical plane in the midline.

Answer:
8 g/cm³
Explanation:
density=mass/volume
volume=2*2*2=8 cm³
mass=64 g
density=64/8=8 g/cm³
The density of a 2 cm x 2 cm x 2 cm cube with a mass of 64 g is equal to 8 g/cm³.
What is the density?Density can be defined as the material mass per unit of volume. The symbol commonly used to represent density ρ and the letter 'D' can also be used.
The mathematical equation of the density can be represented as written below:
Density = Mass /Volume
or, ρ = m/V
The density of a material varies with pressure and temperature. There is a small variation for solids and liquids of any material but much larger for gases. Increasing the pressure of material decreases the volume and thus increases its density.
Given the volume of the cube = 2 cm x 2 cm x 2 cm
V = 8 cm³
The mass of the cube, m = 64 g
The density of the cube can be calculated from the above-mentioned formula:
Density = Mass of cube/volume
D = 64/8
D = 8 g/cm³
Therefore, the density of the cube is 8 g/cm³.

) A 1.0kW kettle contains 500g of boiling waterCalculate the time needed to evaporate all the water
in the kettle (specific latent heat of vaporization2.26 MJ kg-1
Answer:
t = 1130 s = 18.83 min
Explanation:
First, we will calculate the energy required to evaporate 500 g of water:
[tex]E = mL[/tex]
where,
E = Energy Required for evaporation of water =?
m = mass of water = 500 g = 0.5 kg
L = Latent heat of vaporization of water = 2.26 MJ/kg = 2260 KJ/kg
Therefore,
[tex]E = (0.5\ kg)(2260\ KJ/kg)\\E = 1130\ KJ[/tex]
Now, we will calculate the time required:
[tex]P = \frac{W}{t}\\\\t = \frac{W}{P}[/tex]
where,
t = time = ?
P = Power of kettle = 1 KW
Therefore,
[tex]t = \frac{1130\ KJ}{1 KW}\\\\[/tex]
t = 1130 s = 18.83 min

At high elevations or high latitudes, some of the water that falls on land does not immediately soak in , run off, evaporate or transpire. where is the water being temporarily stored?
Answer:
The water is stored in ice sheets and as snow
Explanation:
Temperature reduces with an increase in altitudes. The standard laps rate is 6.5°C per 1,000 m gained in elevation
At very high elevations, therefore, the air is usually very cold such that when an elevation of 4,500 meters is reached at the equator, it is possible to observe snowfall and the water remain temporarily stored on the surface of the mountain as ice and snow

Why does grass look black under the moonlight?
Answer:
The moon doesn’t have light of its own, the moon lights up because of the sun. So at night, as the light of the sun doesn't reach the grass directly because of the moon, it doesnt reflect any color off the grass, and so our eyes detect grass as black.
Explanation:
Sun appears white, but it is made up of the colors: red, orange, yellow, green, blue, indigo, and violet. When white light hits an object, it absorbs some colors and reflect the others. Grass appears green because it absorbs all the wavelengths except green. Green is reflected off the grass, so we see grass as green.

Where P = power, V = Voltage, R = Resistance
Given: V = 120 volts, R = 15 ohms.
Substitute these values into equation 1
