The amplitude of a sound WAVE determines its loudness or VOLUME. A larger amplitude means a louder sound, and a SMALLER amplitude means a softer sound. The frequency of a sound wave is what your ear understands as pitch. A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch
The human ear can detect a wide RANGE of frequencies. Frequencies from 20 to 20 000 HZ are audible to the human ear

Can we do it tomorrow or girl yet I am in a few HOURS and then I am in 12 will not say ANYTHING to you please help can you give TIPS on what you have any bf and the kids will be here tomorrow if you don't have TIME to get together with me and you

E=mc² was FIRST DERIVED from
m=e/c²

No...Not EVERYTIME 'cause sometimes it is linear
if it is wrong don't mnd i'm a 10th class STUDENT but as far as i've STUDIED i'm RIGHT

HERE IS THE ANSWER;

◆ The magnitude of the RESULTANT will be POSITIVE. As magnitude cannot be NEGATIVE or we can SAY that DISTANCE cannot be Negative.

There are just so many things that we take for GRANTED: our teeth, our neighbor’s WiFi password, and even the existence of life on Earth! The three things that I listed here are absolutely unrelated, but that’s not the point I’m trying to make. I’m trying to express how the smallest and most obvious things that happen EVERY single moment all around US shouldn’t be taken for granted. If everything on this planet stopped moving suddenly, it could mean INSTANT OBLITERATION of life as we know it.

How they are used

Using drilling liquids and muds accomplishes four things:

reduce the amount of friction on the drilling rig

stabilize the walls of the hole to prevent a cave in

carry out debris, called CUTTINGS, from the hole

suspending the cuttings when there is a pause in drilling, as when the rig is brought in and out of the hole


Both liquid and mud are used to drill boreholes but the COMPOSITION is DIFFERENT. One term is often used for the other, but strictly speaking gaseous drilling fluid, using an array of gases, is a fluid. But fluids that are water or oil based are called mud.

seven basic types of drilling fluid though technically some are actually fluid and some are mud. What geotechnical engineers use depends on the type of drill they are using, the geology of the area and what they are drilling for.

compressed air

a mix of compressed air and water. Its advantage is the GREATER cooling it provides and better control of dust.

a mix of compressed air, water and polymer, often used as foaming agents

water by itself, often used in offshore drilling

water-based mud, which is water plus clay and chemicals

oil-based mud, which is mud with a petroleum product like diesel. It has greater lubricating and cleaning ability.

synthetic-based fluid, also called low toxicity oil based mud. Its big advantage is fewer TOXIC fumes, essential in enclosed spaces on offshore rigs.

Answer:

we know that initial velocity of a particle will be 0.

1)GIVEN time =5 seconds, Distance =10 m/s

s=ut+1/2a*t^2

10=u×5+1/2*a*(5)^2

10=5u+25a/2

10-(5u+25a/2)=0

-5(2u+5a-4)=0

2u+5a-4=0

2u +5a=4.......(1)

(2) given time =5+3=8 seconds, Distance =20m

s=ut+1/2a*t^2

20=8u+1/2*a(8)^2

20=8u+64a/2

20-(8u+64a/2)=0

20-8u-32a=0

-4(2u+8a-5)=0

2u+8a-5=0

2u+8a=5........(2)

on solving (1) and(2) we get

4-5=2u+5a-2u-8a

-1=-3a

a=1/3.....(3)

substitute (3) in (2) we get

2u+8a=5

2u+8(1/3)=5

2u+8/3=5

6u+8=15

6u=7

u=7/6.........(4)

therefore the distance covered in first 10 seconds

s=ut+1/2at^2

=7/6*10+1/2*1/3(10)^2

=70/6+100/6

=170/6

=28.3m

therefore the distance TRAVELED by the particle in next 2 seconds

=28.3-20

=8.3m

This simple looking object was made by Michael Faraday in 1822.  Its simplicity masks its true importance as the first surviving electric motor. 

In 1820 Hans Christian Ørsted announced his discovery that the flow of an electric current through a wire produced a magnetic field around the wire. André-Marie Ampère followed on and showed that the magnetic force APPARENTLY was a CIRCULAR one, producing in effect a cylinder of magnetism around the wire. No such circular force had ever before been observed.

Self-taught British scientist Michael Faraday (1791 – 1867) was the first to understand what these discoveries implied. If a magnetic pole could be isolated, it ought to move constantly in a circle around a current-carrying wire.

In 1821 Faraday set about trying to understand the WORK of Ørsted and Ampère, devising his own experiment USING a small mercury bath. This device, which transformed electrical energy into mechanical energy, was the first electric motor.

This apparatus is the only original surviving example made by Faraday the following year after his discovery in 1822.

The motor features a stiff wire which hang down into a glass vessel which has a BAR magnet secured at the bottom.  The glass vessel would then be part filled with mercury (a metal that is liquid at room temperature and an excellent conductor). Faraday connected his apparatus to a battery, which sent electricity through the wire creating a magnetic field around it. This field interacted with the field around the magnet and caused the wire to rotate clockwise.

This discovery led Faraday to contemplate the nature of electricity. Unlike his contemporaries, he was not convinced that electricity was a material fluid that flowed through wires like water through a pipe. Instead, he thought of it as a vibration or force that was somehow transmitted as the result of tensions created in the conductor

Light, generally travels by fluctuating in different directions.

Polarizer is a device to produce light moving only in one direction and vibrations of light waves to be only in one direction.

When light PASSES through polarizer, the part of light wave vibrating in different directions are being stopped by polarizer and the part of light wave whose vibrating axis is parallel to polarizer axis only passes through it.

Thus, as a result the INTENSITY of light wave GET REDUCED by passing through a polarizer.

This PROPERTY of a MATTER is KNOWN as PLASTICITY.

O₂ is a diatomic molecule . HENCE , there are five degree of freedom for 1 MOLE of O₂ gas .In which 3 translational and 2 ROTATIONAL .
∴ degree of freedom for 1 mole of O₂ gas , f = 2 [ for rotational motion ]
We KNOW,
Average Rotational Kinetic energy =
Here f is degree of freedom for rotational motion.
∴ average Rotational Kinetic energy = 2/2 RT = RT

Solution:

MASS of body, m= 10kg

velocity, v= 60m/s

Now,kinetic ENERGY on earth= potential energy at a that POINT [energy conservation]

so, kinetic energy= 1/2*m* v^2

= 1/2* 60(60)^2

= 30* 60*60

= 108000 JOULES

According to the question, the fraction is : -


We ADDED 9 to both, NUMERATOR and DENOMINATOR, then the fraction BECOMES 11/15.
So,

Energy of a charge distribution in a spatially non-uniform external electric FIELD. We also derive the multipole expansion for the energy of two RIGID, non-overlapping charge distributions. The results are expressed in both cartesian tensor and circular tensor forms. Some interesting differences from the three-dimensional case emerge : for example, in any order the multipole moment has at most two INDEPENDENT components; and there is no unique preferred relative orientation for two interacting multipoles, which implies that in some respects, at least, the physics of a 2D fluid MAY differ appreciably from that of its 3D analogue.

When an ELECTRO GAINS some velocity ...it creates a ELECTRIC filed AROUND it.....but when it accelerates. .it cretaes both the magnetic filed and the electric field. .

A theodolite plus SATELLITE location(gps ou other SYSTEM)plus eletronic distance metering plus collecting and storaging data, are the TS. Can be USED in ROUGH TERRAIN and water space .....so big try internet

In solving this problem, we will assume that the metre scale has no weight

Taking moments;

Anticlockwise moments = clockwise moments

0.6 x 50 = 1 x y (y is the distance of the second force from the centre)

y = 30

This means the 1N force MUST be suspended (50 - 30) = 20 cm from the other end.

The answer is 20 cm.

FiberGlass and plastic foams does not CONDUCT electricity or its a bad conductor because:

Glass is mostly silicon oxide, a covalent compound .
Covalent compounds share electrons from each of the constituent elements ( silicon and oxygen) to bond those elements together as a compound; TWO atoms of oxygen for each atom of silicon. some glasses have additions of ionic compounds.
Conduction of electricity requires some mobility of electrons to move that POTENTIAL charge through the material.
Electrons in covalent and ionic compounds in glass are too TIGHTLY bound to the molecule to conduct electricity.
Therefore, fiberglass and plastic foams does not conduct electricity.
Most metals conduct electricity because metal atoms are bound by metallic bonds that share a “cloud” of mobile electrons that are free to move within the normal crystalline STRUCTURE

Option C the NET force on the OBJECT is zero
