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

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.

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.

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.

Force = mass * acceleration

Force = 47 * 3.8

Force = 178.6 Newton.

5. Given the following data;

Force = 785N

Mass = 345kg

Acceleration = force/mass

Acceleration = 785/345

Acceleration = 2.28 m/s²

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.

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.

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)

Explanation:

Use a meter stick, small metal ball, stopwatch, calculator.

Have the students mark off a vetrtical distance from which to drop the metal ball. Ready the stopwatch, and start when the object is dropped and stop when the object contact the ground. Repeat 5 times and average the stopwatch times.

Now, use the formula d=vo+(1/2)at^2

There's no initial velocity, so d=(1/2)at^2

We know time and distance, so we can solve for a, acceleration.

2d=at^2

(2d)/(t^2)=a

Now, input the numbers gathered in the experiment in meters and seconds.

One source of error is human error (stopwatch timing)

Since steel contains iron (a magnetic metal), the magnets will attract the steel cans since aluminum is not magnetic. This is used to separate the steel cans from the aluminum cans so they can be recycled separately.

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

4. Defibrillator.

5. Capacitors.

6. Energy.

7. Resistor.

Explanation:

Resistance is the difficulty of passing electric current through a conductor. It increases as the wire becomes longer and decreases as the wire becomes wider.

Defibrillator are electric devices used to transform energy into heat or light.

Capacitors are similar to batteries. They can store energy. But they charge up quicker and can discharge all the the energy faster than a second. A resistor is an example of a capacitor function.

Answer:

E p = m · g  · h

E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J

E p ( picture frame ) = 6.86 J  

( same gravitational  potential energy as the book )

6.86 = 0.5 · 9.8 · h

6.86 = 4.9  h

h = 6.86 : 4.9

h = 1.4 m

Answer: 1.4 M

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:

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:

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.
