## The Calculator Encyclopedia Calculates and Solves the Wavelength for a Wave – Particle Behaviour

According to Wikipedia,

Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be partly described in terms not only of particles, but also of waves.

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave’s shape repeats.

Nickzom Calculator requires two parameters to compute the wavelength of a wave or particle. These parameters are:

• Mass
• Velocity

The formula for computing the wavelength is:

λ = h / mv

Where:
λ = Wavelength
h = Planck’s Constant (6.63 x 10-34 js)
m = Mass
v = Velocity

Let’s solve an example, find the wavelength of a wave – particle with a mass of 300 Kg and a velocity of 3 x 1010 m/s.

From the example, we can see that:
m = 300
v = 3 x 1010

λ = 6.63 x 10-34 / 300 (3 x 1010)
λ = 6.63 x 10-34 / 9 x 1012
λ = 7.37 x 10-47

Therefore, the wavelength of the wave – particle (λ) is 7.37 x 10-47.

## How to Calculate the Resultant of Two Vectors (Physics)

According to Math Warehouse,

The resultant vector is the vector that ‘results’ from adding two or more vectors together.

The formula for calculating the resultant of two vectors is:

R = √[P2 + Q2 + 2PQcosθ]

Where:
R = Resultant of the Two Vectors
P = Magnitude of the First Vector
Q = Magnitude of the Second Vector
θ = Inclination Angle between the Two Vectors

Let’s solve an example, find the resultant of two vectors where the first vector has a magnitude of 30 and the second vector has a magnitude of 40 with 50° has the inclination between the two vectors.

From the example above, we can see that P is 30, Q is 40 and θ is 50. Now, inserting these values into the formula we compute for the resultant of the two vectors.

R = √[(30)² + (40)² + 2(30)(40) . cos50°]
R = √[900 + 1600 + 2(1200) . (0.6427876096865394)]
R = √[900 + 1600 + 2400(0.6427876096865394)]
R = √[900 + 1600 + 1542.6902632476945]
R = √[4042.6902632476945]
R = 63.58215365373915

Therefore, the resultant of the two vectors is 63.58215365373915.

To be able to get the resultant of two vectors using Nickzom Calculator. You need to know the magnitude of the two vectors and the inclination between the two vectors.

## Nickzom Calculator Calculates Conception and Best Intercourse Dates

## Nickzom Calculator Calculates Basal Metabolic Rate

According to Wikipedia,

Basal Metabolic Rate is a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining “standard” rates of metabolism for many mammals.

Basal Metabolic Rate is the rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food).

Nickzom Calculator is the very first calculator encyclopedia to come out from Nigeria. It is capable of solving over 50,000 calculations and presenting the steps (workings). Fortunately, Nickzom Calculator can solve for your body metabolic rate.

## How to Calculate the Difference between Two Dates | Nickzom Calculator

Have you ever wondered how you can know the difference between two dates down to the days, hours, minutes and/or seconds? I have.

I can remember when I thought of it. I wanted to know the number of days remaining for me to be done with my National Youth Service Corp Scheme. I then decided to develop an app that could tell me the difference in hours between two dates and also provide me with the information of other units as well. Curious much? yes.

Today, I would very much like to inform you that you can also find out the remaining seconds or minutes for the year of 2018 to be over.

To get answers for the difference between two dates is very easy. All you need are the two dates (start date and end date).

For the purpose of this post made on the 16th of December, 2018. I would like to know the number of minutes left for me to see 2019.

Therefore, our start date is 16 December, 2018 and our end date is 1 January, 2019.

## How to Calculate and Solve for Linear Expansivity, Area Expansivity and Volume or Cubic Expansivity

Linear expansivity, area expansivity and volume or cubic expansivity are all parameters that are being governed by heat energy. All three parameter is dependent on temperature rise which is primarily in Celsius unit of temperature.

Linear expansivity additionally depends on the original length and final length, area expansivity additionally depends on the original area and final area and lastly, cubic or volume expansivity depends on the original volume and final volume.

The formula for calculating linear expansivity is (l2 – l1) / l1θ
l2 represents the final length.
l1 represents the original length.
θ represents the temperature rise in Celsius.

The formula for calculating area expansivity is (A2 – A1) / A1θ
A2 represents the final area.
A1 represents the original area.
θ represents the temperature rise in Celsius.

The formula for calculating volume or cubic expansivity is (V2 – V1) / V1θ
V2 represents the final volume.
V1 represents the original volume.
θ represents the temperature rise in Celsius.
