Answer:

<h2><em>A or</em> <em>Alex > Chai > Jimmy > Sanni</em></h2>

Explanation:

__________________________________________________________

<em>Here's why this is the answer,</em>

<em>__________________________________________________________</em>

<em>Alex's Range = 3.20 - 0.90 = 2.30</em>

<em>Sanni's Range = 1.35 - 1.30 = 0.05</em>

<em>Chai's Range = 2.10 - 1.05 = 1.05</em>

<em>Jimmy's Range = 2.20 - 1.55 = 0.65</em>

__________________________________________________________

<u>Greatest to Least</u>

<em>Alex > Chai > Jimmy > Sanni</em>

<em>Here's why this is correct.</em>

<em>Alex = 2.30</em>

<em>Chai = 1.05</em>

<em>Jimmy = 0.65</em>

<em>Sanni = 0.05</em>

<em>I do not see the answer I have on this question so I think it is A.</em>

<em>__________________________________________________________</em>

<em>Hope this helps! <3</em>

an aircraft has a liftoff speed of 53 m/s. what is the minimum constant acceleration an airplane must have to reach that takeoff
xxMikexx [17]

Answer:

a=3.34\ m/s^2

Explanation:

<u>Accelerated Motion </u>

It refers to the motion of objects in which velocity is not constant over time. If the change of the velocity occurs at the same rate, then we say it's uniformly accelerated. Being   v_o= initial speed, v_f= final speed, a= constant acceleration, x= distance traveled

Then, the scalar relation between them is

v_f^2=v_o^2+2ax

The aircraft needs to reach a liftoff speed of 53 m/s from rest (assumed) having only 420 meters to do so. We can compute the acceleration by solving for a

\displaystyle a=\frac{v_f^2-v_0^2}{2x}

\displaystyle a=\frac{53^2-0^2}{2(420)}

\boxed{a=3.34\ m/s^2}

HELP PLEASE!! GIVING BRAINLIEST!! If you answer this correctly ill answer some of your questions you have posted! (20pts)
anyanavicka [17]

Explanation:

potential energy =360800J

mass(m)=?

height (h)=25m

g=9.8m/s²

we have

potential energy =360800J

mgh=360800J

m×9.8×25=360800

m=360800/(9.8×25)=1472.653061kg

What is the saturated zone
uranmaximum [27]

Answer:

Saturated zone is area below the water table in which the soil is completely saturated with groundwater.

Explanation:

The saturated zone lies below the ground. It is mainly the lower zone of rock along with the water table where pore spaces are completely filled with water. Even the saturated zone is sometimes separated into 2 subzones: the phreatic zone and the capillary fringe.

The area where pores spaces are not saturated with water is also unsaturated zone. Localized saturated zones can occur within the unsaturated zone. The unsaturated zone lies above the groundwater table.
