The resonant frequency of a driven rlcrlc circuit is 1600 hzhz. The resonant frequency is doubled if the resistance rr is doubled
The natural frequency at which a material vibrates with the greatest intensity is called the resonant frequency. The symbol for resonance is typically f0. Resonance is seen in items that are in balance with the forces at work and, in ideal circumstances, could vibrate indefinitely.
A resonant frequency is a natural vibrational frequency in sound applications that is established by the physical characteristics of the vibrating object.
The resonant frequency is advantageous because, in the event of resonance, the oscillation's deflection increases. In acoustics, a greater sound wave amplitude results in greater sound pressure and, thus, a greater volume. For loudspeakers, resonant frequencies are typically undesired.

If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected?.
The voltage remain constant
According to Ohm's Law:
V = IR
If we halved the resistance let:
R'=R/2
then
I'=21 in order to kept the Voltage same. Also the resistance is the opposition to the current. So, if resistance will halved then obviously current will double
So when we put these value in to Ohm's Law the results is:
V'=I'R'
V'=21(R/2)
V'-IR which is equal to first voltage. Hence,

steel is
almost entirely of iron atoms,
but it is denser than iron.
Suggest
reason for this.
Steel is denser than iron because it has carbon atoms entangled inside the latticework of iron atoms.
What is the difference between iron and steel?Iron is first and foremost an element, whereas steel is an alloy of iron and carbon. The amount of iron is higher in this alloy, though. Steel can be alloyed with various other metals to create materials with various qualities. For instance, stainless steel is produced when chromium is added to steel. It resists rusting quickly and is enduring. Steel is extensively used in the building sector. This is so because steel has better compression and tension properties than iron and is stronger than iron.By examining the carbon percentage, another difference can be seen. Steel is iron that includes less than two percent carbon, whereas pig iron contains more than two percent carbon. Pig iron is produced in a blast furnace by processing iron ore and coke. Steel is produced by further processing this pig iron to lower the carbon content in multiple furnaces. Steel may now be treated further to produce a variety of alloys. Elements such as silicon, manganese, and chromium are added to create alloys.Looking back in time, it is unclear exactly when the technology for manufacturing iron was developed. However, according to some archaeological discoveries, iron was reportedly utilized to make tools in Egypt about 3000 BC. A little later, about 1000 BC, the Greeks produced weapons made of hardened iron. Thus, up until 1400 AD, all other types of made iron could be grouped under the heading of wrought iron. The size of the furnaces used in smelting only rose after the fourteenth century. The upper portion of these furnaces was pushed with iron. It was turned into metallic iron and then exposed to carbon-rich vapors via a blast so that it would absorb them.Steel is denser than iron because it has carbon atoms entangled inside the latticework of iron atoms.

A tortoise can move with a speed of 10.0cm/s, while a rabbit can move 10 times faster. In a race, both of them started at the same time, but the rabbit stopped to rest for three minutes. The tortoise wins by a distance of 10cm from the rabbit. How long is the race?
A. 125.2s
B. 159.8s
C. 199.9s
D. 205.7s
Answer:
C. 199.9 s
Explanation:
3 minutes = 3×60 = 180 seconds.
the turtle moves in that time 180×10 = 1800 cm.
in other words the rabbit gave it that much head-start (it does not matter if that was at the begin of in the middle of the race).
the rabbit moves with 10×10cm/s = 100cm/s.
the rabbit needs therefore 1800/100 = 18 seconds for the
1800 cm.
at that time the turtle has added another 18×10 = 180 cm.
for which the rabbit needs 180/100 = 1.8 seconds.
during that time the turtle has added 1.8×10 = 18 cm.
and so on.
in formal mathematics this looks like this :
1800 + 10x = 100x
after x seconds of the rabbit running both will have run the same distance, and it is a tie.
1800 = 90x
x = 20 seconds
so, at that point, the rabbit was actively running for 20 seconds and raced 20×100 = 2000 cm
and the turtle was actively running for 180 + 20 = 200 seconds, and also covered 200×10 = 2000 cm.
but our question tells us that the turtle won by 10 cm.
so, the race was over a little bit before these 200 seconds (for a tie).
this means, the rabbit could not run the last 10 cm for the tie (because the race was over and the turtle had won).
the rabbit would have needed 10/100 seconds for these 10 cm.
as speed = distance/time
we need to divide distance by speed
distance/1 / distance/time
to get time.
so,
10cm/1 / 100cm/s = 10s/100 = 1/10 s
so, we need to deduct this 1/10 s from the 200 seconds of the turtle (and also from the 20 seconds for the rabbit).
the race lasted of course the whole time the turtle was running (while the rabbit was resting, officially still participating in the race with speed 0 for 3 minutes).
and so, the race was 199.9 s long.

On an equipotential surface , the potential difference between any two points is zero. So , the work done by the electric field on a test charge moving on the surface will be zero. Therefore , the electric field must be perpendicular to the surface at every point . Hence electric force must have the same direction , that is perpendicular to the surface.

The lowest frequency of a guitar string with a length 0. 65 m is 248 hz. what is the speed of the wave on this string?
The speed of the wavelength on this string 322.4 m/s.
Given,
Half wavelength = 0.65m,
So, Wavelength = 2*.65=1.3m, frequency=248Hz
Speed=wavelength*frequency=1.3*248=322.4 m/s.
WavelengthThe wavelength, or spatial period, of a periodic wave in physics refers to the length over which the wave's structure repeats. It is the separation between neighbouring wave points that correspond to the same phase, such as two adjacent crests, troughs, or zero crossings. It is a property of both travelling waves and standing waves as well as other spatial wave patterns. The spatial frequency is the wavelength's reciprocal. The Greek letter lambda (), which represents wavelength, is frequently used. When describing modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids, the term wavelength is also occasionally used.

Imagine that heike onnes cooled mercury down to absolute zero and there was still resistance. would he have discovered superconductivity? yes, because he was working with mercury, which has superconductive properties yes, because he would have observed it at 4.2 k no, because superconductivity cannot occur in mercury since it is a liquid no, because superconductivity cannot occur if there is resistance
No, because superconductivity cannot occur if there is resistance
In addition to explaining electrical resistance, equilibrium distance theory also foretells the existence of superconductivity. According to its postulates, electrical resistivity decreases with distance from the equilibrium. There is only superconductivity at zero distance, with no resistance
What is Superconductivity ?The ability of some materials to transmit electric current with virtually little resistance is known as superconductivity.
This ability has intriguing and maybe beneficial ramifications. Low temperatures are necessary for a material to exhibit superconductor behaviour. H. K. made the initial discovery of superconductivity in 1911.Aluminum, magnesium diboride, niobium, copper oxide, yttrium barium, and iron pnictides are a few well-known examples of superconductors.Learn more about Superconductivity here:
