Explanation:

Thermal distillation involves heat: Boiling water turns it into vapor—leaving the salt behind—that is collected and condensed back into water by cooling it down. ... Pumping this supersalty water back into the ocean can harm local aquatic life.

Calculate the value of two equal charges if they repel one another with a force of 10 N having 10 m distance apart in a vacuum.
MAVERICK [17]

Explanation:

a) From Coulombs law,

F = (kq1q2)/r²...............1

F = 10 N

r = 10m

k = 9 × 10^9 m/F

q1 = q2

from equation 1, make q the subject

q = (Fr²)/2k

q = (10×10²)/(2×9×10^9)

q = 1000/1.8×10^10

q = 5.556×10^-8 C

b) K = k/ko

k = Kko = 10times permittivity of free-space

Goodluck

A car traveling in a straight line at an initial speed of 8.0 meters per second accelerates uniformly to a speed of 14 meters pe
Whitepunk [10]

The equation we can use here is:

v^2 = v0^2 + 2 a d

where v is final velocity, v0 is intial velocity, a is acceleration and d is distance

 

14^2 = 8^2 + 2 a (44)

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}
