Answer:

gathered by using measurement tools and math

Explanation:

Quantitative data is often gathered by using measurement tools and math.

A quantitative data set is assigned values and numbers in order to solve a problem or for the purpose of a study.

Each data set has a unique numerical value and can be counted.
Qualitative data set does not use numerals and numbers.
It engages the senses to make some scientific deductions.
Examples are measurement of volume, distance, length, time, number of moles e.t.c
Qualitative data sets include taste, smell, color e.t.c

To solve the exercise it is necessary to take into account the concepts of wavelength as a function of speed.

From the definition we know that the wavelength is described under the equation,

$\lambda = \frac{c}{f}$

Where,

c = Speed of light (vacuum)

f = frequency

Our values are,

$f = 2Hz$

$c = 3*10^8km/s$

Replacing we have,

$\lambda = \frac{c}{f}$

$\lambda = \frac{3*10^8km/s}{2Hz}$

$\lambda = 1.5*10^8m$

<em>Therefore the wavelength of this wave is $1.5*10^{8}m$ </em>

Complete Question

A parallel plate capacitor creates a uniform electric field of 5 x 10^4 N/C and its plates are separated by 2 x 10^{-3}'m. A proton is placed at rest next to the positive plate and then released and moves toward the negative plate. When the proton arrives at the negative plate, what is its speed?

Answer:

$V=1.4*10^5m/s$
