A more reasonable maximum acceleration for varying pavement conditions is 5.0 m/s2 . under these conditions, what is the maximum speed at which a car can negotiate a flat curve with radius 205 m ?

Sound from the siren of an emergency vehicle has a frequency of 667.2 hz and moves with a velocity of 349.8 m/s, thus the distance from one condensation to the next is 0.52m.

Waves of sound exist. A disturbance of matter that is conveyed from its source outward is how sound is more precisely defined. Anything that is shifted out of its balance is considered a disturbance.

Some sound waves are classified as periodic waves, which means that the matter’s atoms move in a straightforward harmonic fashion.

As, a string vibrating creates a sound wave. A portion of the string’s energy is used to compress and expand the surrounding air as it oscillates back and forth.

Pressures are a little bit higher and lower as a result. Low pressure regions are rarefactions, and higher-pressure regions are compressions. The air is moved by the pressure anomaly.

Provided that,

∨= 667.2 hz

V= 349.8 m/s

The effect after the current is tripled is changing the drift velocity by a factor 3.

We need to know about drift velocity of electrons to solve this problem. The drift velocity can be determined as

v = I / (n . A . q)

where v is drift velocity, I is current, n is atom number density, A is surface area and q is the charge.

From the question above, we know that

I2 = 3 . I1

According to drift velocity formula, the drift velocity is proportional to current

v ~ I

Hence, the ratio of drift velocity and current is

v1 / v2 = I1 / I2

substitute the final current (I2)

v1 / v2 = I1 / (3.I1)

v1 / v2 = 1 / 3

The thickness of an anti-reflective coating is 96 nm.

Define Wavelength?

The wavelength in waves is defined as the distance between the crests and troughs. It can be calculated in the meter in the SI system. The crest is the upper part of the wave, and the trough is the lower part.

Given that,

The index of the anti-reflective coating is n = 1.3

The wavelength is denoted as  λ = 500 nm = 500×[tex]10^{-9}[/tex]m

The expression for interference can be written as

2t = (m+½)λf

m=0 is the minimum reflection order.

λf is referred to as the wavelength of the film.

By substituting the values in the above expression we get,

2t = (m+½)λf

2t = (0+½)λf

t = λf/4 (this will noted as equation 1 for more clarity )

The wavelength of the light in a medium with refractive index can be expressed as

λf = λ/n

By substituting the values in equation1 we get,

t = λf/4

t = (λ/n)/4

t = λ/4n = 500/(4×1.3) = 96 nm.

Kilopascal (kPa), a 1,000-fold increase in the meter-kilogram-second system’s measure of pressure and tension (the International System of Units [SI]).

Blaise Pascal, a French mathematician and scientist, is honored by its name.

The formula below can be used to translate kg/cm2 into kPa:

A kPa equals 1000 pascals (Pa)

1 kg/cm2 is equal to 98066.5 pascals (Pa), or kPa value multiplied by 1000 Pa.

Thereafter,

T = 26°C

= 299K

P = 100kPa

P= 100/101.325

=0.986923 atm

mass = 3.25g

Atomic mas of H = 1.00784

molar mass of H2 gas = 2x10.00784

= 2.01568g/mol

mole of H2 in 3.25g = 3.25/2.01568 = 1.612359 mol

This gas provided in the question follows the ideal gas equation, so it can be written as

The reaction between copper(Cu) and nitric acid(HNO3) is as follows:

Cu + HNO3 = Cu(NO3)2

According to the above reaction

1 mole of copper produces 1 mole of copper nitrate

Or 63.5 g of copper produces 1 mole of copper nitrate

Thus, 0.9075 g of copper produces 1/63.5 x 0.9075 = 0.0143 moles of copper nitrate

The reaction between sodium hydroxide(NaOH) and copper nitrate {Cu(NO3)2} is as follows:

The index of refraction of a material in which the red-light wavelength is 450 nm is 1.38≤n≤1.67.

Refractive Index (Index of Refraction) is a value calculated from ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by letter n or n' in descriptive text and mathematical equations.

The refractive index  n  is the factor by which wave slows down relative to the speed of light in vacuum  c0 . Almost always, frequency of a wave is constant and so it is the speed and wavelength that change as light passes from one medium into another.

So the wavelength  λ  inside of the medium is related to free space wavelength  λ0  through the refractive index  n .

λ=λ0/n

Red light has free space wavelength  λ0  of anywhere from 620 nm to 750 nm. All of those of wavelengths look red to our eyes. From above equation refractive index is

n1=λ0/λ=620 nm/450 nm=1.38

n2=λ0/λ=750 nm/450 nm=1.67

Based on information you gave, the refractive index could be anything in the range 1.38≤n≤1.67.
