Answer: It is important to use both QUALITATIVE and QUANTITATIVE data because the limitations of one type of data are counteracted by the advantages of the other.

Explanation:

QUALITATIVE data defined as type of data that centers on the measurement of the features of the subject under study. This is obtained through careful observations. It is a non numerical type of data. Some examples includes: sex(male or female), name, and colours. The limitations of using only qualitative data for a research includes:

--> it can not be statistically represented

--> the results can not be verified

--> it is time consuming and

--. It requires alot of labor.

QUANTITATIVE data is defined as the type of data that centers on the measurement of the amount and quantity of the subject under study. It can be used to conduct a large study than qualitative data. Examples include the heights and weights of students. The limitations of quantitative research includes:

--> poor representation of target population

--> inability to control the environment and

--> lack of resources for data collection.

Therefore, It is important to use both QUALITATIVE and QUANTITATIVE data analysis because the limitations of one type of data are counteracted by the advantages of the other. I hope this helps, thanks!

When placed in a ________ solution, a cell will exhibit a net loss of water. the specific process by which the water leaves the
katen-ka-za [31]

The specific process by which the water leaves the cell is called <u>plasmolysis.</u>

<h3>What is plasmolysis?</h3>

Plasmolysis is the process in which the cell loses the water that is present inside it because the environment of the cells produces pressure to build up inside the cell. If a cell is present in a hypertonic solution means that solvent concentration is lower in the surrounding solution, then water comes out of the cell while on the other hand, if a cell is present in a hypotonic solution in which the solvent concentration is higher in the surrounding solution, then water goes inside of the cell. The movement of liquid inside or outside of the cell occurs due to the semi-permeable membrane of the cell.

So we can conclude that the specific process by which the water leaves the cell is called <u>plasmolysis.</u>

An electron enters a region with a speed of 5×10^6m/s and is slowed down at the rate of 1.25×10^-4m/s². How far does the electro
Mashutka [201]

1) The distance travelled by the electron is 1\cdot 10^{17} m

2) The time taken is 4.0\cdot 10^{10}s

Explanation:

1)

The electron in this problem is moving by uniformly accelerated motion (constant acceleration), so we can use the following suvat equation

v^2-u^2=2as

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance travelled

For the electron in this problem,

u=5\cdot 10^6 m/s is the initial velocity

v = 0 is the final velocity (it comes to a stop)

a=-1.25\cdot 10^{-4} m/s^2 is the acceleration

Solving for s, we find the distance travelled:

s=\frac{v^2-u^2}{2a}=\frac{0-(5\cdot 10^6)^2}{2(-1.25\cdot 10^{-4})}=1\cdot 10^{17} m

2)

The total time taken for the electron in its motion can also be found by using another suvat equation:

v=u+at

where

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

Here we have

u=5\cdot 10^6 m/s

v = 0

a=-1.25\cdot 10^{-4} m/s^2

And solving for t, we find the time taken:

t=\frac{v-u}{a}=\frac{0-5\cdot 10^6}{-1.25\cdot 10^{-4}}=4.0\cdot 10^{10}s

ICE Princess25 [194]

Answer:

a. 41.96ft/s

b. 1.096s

Explanation:

a. v²=u²+2gs

v²=31²+2×10×40

V=41.96ft/s

b. t=(v-u) /g

t=(41.96-31)/10

t=1.096s
