Answer:

A

Explanation:

By repeating trials, you can get the highest and lowest values of the same experiment and in the end get an average result.

This is why when titrating we perform the experiment two to four times, then find the average. That average is the median and therefore the most likely result of the experiment.

asambeis [7]

Answer:

C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.

Explanation:

Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.

Lila is a track and field athlete. She must complete four laps around a circular track. The track itself measures 400 meters fro
tekilochka [14]

Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.

Explanation:

Formulae :\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}

\text{Velocity}=\dfrac{\text{Displacement}}{\text{Time}}

Given: Length of track start to finish=  400 meters

After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters

Time taken by Lila =   6 minutes

= 6 × 60 seconds      [There are 60 seconds in 1 minute.]

= 360 seconds  

Then, \text{Speed}=\dfrac{1600}{360}=\dfrac{40}{9}m/s

= 4.44\ m/s

But from start to finish displacement = 0 m   [displacement is the shortest distance between starting point to the finishing point]

So, \text{Velocity}=\dfrac0{360}=0\ m/s

Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.
