How to calculate the period of a wave?

Answers

Answer:

The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ. The wave frequency and the period are inversely related to one another.

Explanation:

T = 1 / f is the formula to calculate the period of a wave.

What is the period of the wave?

The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds.

The calculation of period of wave is:

The formula for period is T = 1 / f ,

where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.

To get period from frequency, first convert frequency from Hertz to 1/s.

Period refers to the time for something to happen and is measured in seconds/cycle.

In this case, there are 11 seconds per 33 vibrational cycles.

Thus the period is (11 s) / (33 cycles) = 0.33 seconds.

Therefore,

T = 1 / f is the formula to calculate the period of a wave.

Metalloids

Metalloids have properties that are intermediate between metals and non-metals. They have properties that are difficult to characterize.

Physical Properties of Metalloids

State of matter    -     Solid

Lustre              -      Metallic lustre

Elasticity              -      Brittle

Conductivity      -      Semi-conductive in nature

Chemical Properties of Metalloids

Oxidation             -      They are capable of forming glasses.

Alloys                   -       When mixed with metals, they form alloys.

Allotropic             -        Metallic and non-metallic allotropes are formed.

Melting                 -        Few metalloids contract when they are melted.

Compounds         -   Compounds are formed when they react with halogens.

Common Properties of Metalloids

Metalloids are good semiconductors. The reactivity of metalloids is dependent on the properties of the elements they are reacting with. Electronegativity and ionization energy are between metals and non-metals.

Non-Metals

Non-metals are those which lack all the metallic attributes. They are good insulators of heat and electricity. They are mostly gases and sometimes liquid. Some they are even solid at room temperatures like Carbon, sulphur and phosphorus.

Properties of Non metals

Characteristic properties of non-metals are high ionization energies and high electronegativity. Owing to these properties, non-metals usually gain electrons when reacting with other compounds, forming covalent bonds. Among the non-metals, the anionic dopants have a strong influence on the VB. Non-Metal dopants are carbon, nitrogen, fluorine, sulphur and iodine.

General properties of non-metals.

The atoms of non-metals tend to be smaller than those of metals. Several of the other properties of non-metals result from their atomic sizes. Non-metals exhibit very low electrical conductivities. The low or non-existent electrical conductivity is the most important property that distinguishes non-metals from metals. Non-metals have high electronegativities. This means that the atoms of non-metals have a strong tendency to attract more electrons than what they would normally have. Non-metals have high electronegativities. This means that the atoms of non-metals have a strong tendency to hold on to the electrons that already have. In contrast, metals rather easily give up one or more electrons to non-metals, metal therefore easily form positively charged ions, and metals readily conduct electricity. Under normal conditions of temperature and pressure, some non-metals are found as gases, some found as solids and one is found as liquid. In contrast, except mercury, all metals are solids at room temperature. The fact that so many non-metals exist as liquids or gases means that non-metals generally have relatively low melting and boiling points under normal atmospheric conditions. In their solid-state, non-metals tend to be brittle. Therefore, they lack the malleability and ductility exhibited by metals.

Physical Properties of Non-Metals

Ductility is the property of the material to be stretched into wires but non-metals are not ductile except for carbon, as carbon fibres find uses in a wide variety of industries including sports and music equipment. Another property characteristic to metals is absent in non-metals called malleability. They can’t be drawn into sheets as they are brittle and break on applying pressure. They are not lustrous as they do not have any shiny appearance. They are not sonorous and do not produce a deep ringing sound when they are hit with another material. They are also bad conductors of heat and electricity except for graphite.

1. Infer how the height of the lines on a seismograph change with an increase in
earthquake magnitude.

Answers

Answer:

his movement is proportional to the intensity of the earthquake,

Explanation:

An earthquake is a record of the intensity of an earthquake as a function of time.

Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.

And the in x corresponds to time

The lines on a seismograph indicate the magnitude of an earthquake. The lines from the seismograph are indicative of seismic waves that the seismograph has recorded.

When there is a straight line on the seismograph, it means there are no earthquakes. However, if the lines become wiggly, it means that the ground is shaking.

How Earthquake Magnitude is measured

The magnitude of the earthquake is determined from the logarithm of the amplitude of waves recorded by the seismographs.

In order to understand the amplitude of waves, you'd have to be versed with the anatomy of waves. Once the logarithm is computed (after adjustments for the distance between the seismographs and the epicenter of the earthquakes), it is checked against the Richter Magnitude Scale in order to place the earthquake in a category.

For example, an earthquake may be considered moderate if the adjusted amplitude of the waves recorded on the seismograph records 5.3 on the Richter Scale. On the other hand, a rating of 6.3 is considered a strong earthquake.

An Led Light bulb is rated 14 W. How much energy will the light bulb consume if it is on for 1 hour (3600 seconds)

Answers

Answer:

18kW

Explanation:

very LED bulb has a power rating in terms of Watt-hour. It gives the power consumption per hour. For e.g. a 100W light bulb consumes 100W of electricity per hour. If left 'on' for 10 hours, a 100W light bulb costs 1kW and 1 unit of electricity is burned. Because 1 unit = 1 Kw of electricity.

I calculated my electricity consumption in 1 hour with LED Bulb as follows-

LED Bulbs power rating- 15 watt

quantity- 1

No. of hours a day – 12

Wattage in 1 hour – 12(time) x 15(load) x 1(quantity) = 180W = .18kW

So consumption units of power with a LED Bulb consume in 1 hour= .18 Units (because 1 KW = 1 unit)

2. You push a 12.3-kg shopping cart with a force of 10.1 N.
(a) What is the acceleration of the cart?
(b) If the cart starts from rest, how far does it move in 2.50 s?


Plz answer quick

Answers

Answer:

Explanation:

The important part about this problem is the acceleration, which you must find by using

F = ma,

where F is the force applied,

m is the mass,

and a is the acceleration.

F = ma

10.1 N = (12.3 kg)a

a = 0.8211 m/s^2

Now use the kinematics equations.

d = vot + (1/2)at^2

where d is the distance moved,

vo is the initial velocity (0),

a is the acceleration,

and t is the time.

d = vot + (1/2)at^2

d = (0 m/s)(2.5 s) + (1/2)(0.8211 m/s^2)(2.5 s)^2

d = 2.57 m

a. The acceleration of the cart, is 0.821 [tex]m/s^2[/tex].

b. The car moved a distance of 30.63 meters starting from rest.

Given the following data:

Mass of shopping cart = 12.3 kgForce = 10.1 NInitial velocity, u = 0 m/s (since the cart is starting from rest). Time, t = 2.50 seconds.

a. To find the acceleration of the cart, we would apply Newton's Second Law of Motion:

Mathematically, Newton's Second Law of Motion is given by this formula;

[tex]Acceleration = \frac{Force}{Mass}[/tex]

Substituting the given values, we have;

[tex]Acceleration = \frac{10.1}{12.3}[/tex]

Acceleration = 0.821 [tex]m/s^2[/tex]

Therefore, the acceleration of the cart, is 0.821 [tex]m/s^2[/tex].

b. To find the distance covered by the shopping cart, we would use the second equation of motion.

Mathematically, the second equation of motion is given by the formula;

[tex]S = ut + \frac{1}{2} at^2[/tex]

Where:

S is the distance covered. u is the initial velocity. a is the acceleration. t is the time measured in seconds.

Substituting the values into the formula, we have;

[tex]S = 0(2.5) + \frac{1}{2} (9.8)(2.5)^2\\\\S = 0 + 4.9(6.25)[/tex]

Distance, S = 30.63 meters.

Therefore, the car moved a distance of 30.63 meters starting from rest.

What is the average velocity of atoms in 1.00 mol of neon (a monatomic gas) at 2°C? For m, use 0.0202 kg.

Answers

Answer:The average Velocity of the atoms =582.73m/s

Explanation:

Given

Mole of neon gas = 1.00 mol

Temperature = 2°C changing to Kelvin becomes

2°C + 273.15 = 275.15K

Mass = 0.0202 kg

Using the equation that connects the Average kinetic energy with ideal gas equation we have that

Kinetic energy=3/2 nRt

1/2(mv^2) = 3/2 nRt

Where

M = mass,

V = volume.

R = gas constant(8.31 jK-1 mol-1,

t = temperature in Kelvin,

n = number of moles

Putting our known values, we have that

1/2(0.0202 × v^2) = 3/2 (1 × 8.31 × 275.15)

0.0101 v^2 = 3,429.745

v^2 = 3429.745 / 0.0101

v^2 = 339,578.713

v = √339578.713

v = 582.73m/s
