The total pressure is 0.89 atm of the flask containing a mixture at 15° C

The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure. In comparison to the surrounding pressure, gauge pressure is the pressure. Pressure is expressed using a variety of units.

IT is defined as the amount of force exerted per area , so to make a large amount of pressure one can exert a large force or exert a small force for smaller area  , it's S.I unit is pascal

total pressure = sum of all the partial pressure

So total pressure (Ptotal ) = partial pressure of N2 + partial pressure of He + partial pressure of Ne

= (0.32 + 0.15 + 0.42) atm.

= 0.89 atm

So Ptotal = 0.89 atm.

the question is a bit incorrect,

the temperate of the flask is actually 158° C.

The name of the temperature zone that includes the equator is Zone C and is referred to as the tropical zone.

This is referred to as the type of zone which is characterized by areas or regions around the equator. The name tropical was coined from its distinct climate which is usually warm all year round as a result of its very high sun exposure.

The degrees of latitude which this zone covers is 23.5 degrees and is south of the Equator which is therefore the reason why it was chosen as the most appropriate choice.

The crest of an ocean wave moves a distance of given time is 2 m/s.

To know the speed of the wave,

Use the formula,

speed = distance / time

Given,

distance = 20 m

s = ?

Putting values,

s = d / t

s = 20 / 10

s = 2 m/s

Although some individuals may believe that average speed and average velocity are simply two different names for the same quantity, average speed depends on both distance and displacement. The average speed will be greater than the average velocity if an object changes direction while traveling.

The density formula and the procedure we will use is:

ρ = m/v

Where:

Information about the problem:

Converting the volume unit from mL to L, we have:

250 mL * (1 L / 1000 mL) = 0.25 L

Applying the density formula and clearing the mass (m), we get:

m = ρ * v

m = 1.56 g/L* 0.25 L

m = 0.39 g

The net change in the internal energy is 40joules.

Given here, the force (F) = 800N acting over a distance of (D) = 0.05m(1cm = 0.01m)

First, we calculate work done by the formula,

Work done = Force × displacement

Work done = 800× 0.05

= 40joules.

Now, we calculate internal energy the first law of thermodynamics.

Internal Enegy (dE) =dQ + W

dE= 0+40

dE = 40joules.

Thus, internal energy was found to be +40joules.

It is the rate of change of an object's position with regard to time and a frame of reference. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction.

The proportion of total mass of Earth lost every year is 6 x 10²⁰ kg.

Heisenberg's uncertainty principle states that it is impossible to measure the exact position and the momentum of an object at the same time, or energy and time. The more certain one is variable is, the more uncertain the other variable is.

The more accurate we measure position of the object, the more uncertain the momentum of the object becomes.

The uncertainty in the measurement of the mass of the Earth can be assumed to be (1 x 10⁻² %).

The proportion of the mass mass of Earth lost every year is calculated as follows;

m = (0.01/100) x 6 x 10²⁴ kg

m = 6 x 10²⁰ kg

We can determine the total distance travelled by a body with position function s (t) when it moves along a coordinate line without changing direction from t = a to t = b.

We must incorporate the body’s speed |v (t)| to determine the overall distance travelled if the body changes direction once or more during the journey.

Metre

The metre [m] is the SI unit of length and displacement.

Let A is the initial position of the hiker.

After walking 1200 metres north reached point B, after walking 500 metres east due to B. She reached point C.

Total distance travelled = 1200 + 500

The distance from strating point is AC from triangle ABC

AC^2 = AB^2 + BC^2

AC^2 =(1200)^2 + (500)^2

Because Newton could not provide comprehensive proof, his Binomial Theorem is not a "theorem" in the sense of Euclid or Archimedes. Nonetheless, his knowledge and intuition served him well enough for him to construct a useful formula.

Furthermore, his intrinsic conviction in the persistence of patterns led him to believe that the formula that correctly generated coefficients for binomial powers such as (a+b)^2 or (a+b)^3 should also work for powers such as (a+b)^1/2 or (a+b)^−3.

Although Newton did not establish this finding, we do know how he came to it. Newton's explanation is offered in a pair of letters dated 1676 and delivered to Leibniz by Henry Oldenburg of the Royal Society. In it, he describes how he came to his conclusion in a roundabout way.

He was looking at the areas under the curves y=(1−x2)n2  from 0 to x for n=0, 1, 2, 3,.... These are simple to compute for even n. Newton was able to guess the solution for odd values of n by studying patterns and interpolating. Then he recognized that expressing (1−x2)n2 as an infinite series would provide the same results.

Newton wrote :

(P+PQ)mn=Pmn+mnAQ+m−n2nBQ+m−2n3nCQ+…

where P+PQ is the binomial to be considered; mn is the power to which the binomial will be raised "whether that power is integral or (so to speak) fractional, positive or negative"; and A,B,C,... indicate the term immediately preceding it in the expansion.

When compared to the present version, this may appear strange. When you remove the Pmn word from the right side and cancel, you get the more known form:

(1+Q)mn=1+mnQ+(m/n)(m/n−1)2Q2+(m/n)(m/n−1)(m/n−2)2×3Q3+(m/n)(m/n−1)(m/n−2)(m/n−3)2×3×4Q4+…

Thus, in Newton's notation,

A=Pmn

B=mnAQ=mnPmnQ

C=(m−n)2nBQ=(m−n)m(2n)nPmnQ2=(m/n)(m/n−1)2PmnQ^2

A specific number of trials must be conducted. Because the number of rolls (trials) is not fixed, the experiment cannot simply consist of rolling a die until you get a 2.

Every trial must stand alone from the others.

The refractive index is the velocity or the speed of the light through which the ratio is calculated by comparing that velocity to be present in the vacuum by its velocity in any specified medium which can be water or air and this medium is also called secondary medium and this medium should be greater density than the former one. The refractive index is represented by the letter 'n' and the value of the refractive index for air is 1.0003 and in the case of liquid the refractive index values can range from 1.0010 to 1.0060 and the formula for the refractive index calculation is n = c/v where n is the refractive index, c is the velocity or speed of light and v is the phase velocity of light that means when light is some other phase like liquid or air or refractive index can also be defined as the bending of the light when the light passes from one medium to other of different densities.

Given -

The Refractive index of crown glass is = 1.52

The Refractive index of water is = 1.33

The angle of incidence = 40°

To calculate the angle of refraction in water -

Using Snell's law

[tex]n_1 sin \theta i = n_2 sin \theta r[/tex]

[tex]n_1 / n_2 = sin \theta r/sin \theta i[/tex]

Where,

[tex]n_1[/tex] = Refractive index of crown glass

[tex]n_2[/tex] = Refractive index of water

[tex]\theta[/tex] i = incidence angle

Putting the value we will get

1.52 /1.33 = sin [tex]\theta[/tex]r / 40

sin [tex]\theta[/tex]r = sin 40 [tex]\times[/tex] 1.52 / 1.33

sin [tex]\theta[/tex] r = 0.715

So, theta r will be

Light with a frequency of 7.30 x 10¹⁴ that lies in the violet region of the visible spectrum has a wavelength of 412nm.

The wavelength of light can be defined as the distance between two successive crests, or troughs of a wave of light, usually denoted by the Greek letter, lambda (λ).

Wavelength is directly proportional to frequency. This means that the shorter the wavelength, the higher the frequency. To find the wavelength of any electromagnetic wave if we are given the frequency, we use the following formular:

                    λ = [tex]\frac{v}{f}[/tex]

Where;

The velocity or speed of light is the same for all electromagnetic waves which is 3 x 10⁸m/s. We are already given the frequency in the question as 7.30 x 10¹⁴hz. Putting these values into the formular:

                      λ = 3 x 10⁸/7.30 x 10¹⁴

                      λ = 4.12 x 10⁻⁷m

However, to convert the wavelength from meter to nanometer, we would have to multiply the answer by 10⁹. Therefore;
