The time difference between their landing is 2.04 seconds.
<h3>
Time of difference of the two balls</h3>
The ball thrown vertical upwards will take double of the time taken by the ball thrown vertically downwards.
Time difference, = 2t - t = t
t = √(2h/g)
where;
- h is the height of fall
- g is acceleration due to gravity
Apply the principle of conservation of energy;
¹/₂mv² = mgh
h = v²/2g
where;
h = (20²)/(2 x 9.8)
h = 20.41 m
<h3>Time of motion</h3>
t = √(2 x 20.41 / 9.8)
t = 2.04 s
Thus, the time difference between their landing is 2.04 seconds.

Well since we're doing the Lewis dot diagram do you know which element on the table that it is?
Answer:
Explanation:
As it is given that flow rate in the pipe is 20 cm^3/s
so we have
at the upper end the area is given as
Also at the other end
now the speed at two ends is given as
now by Bernoulli's theorem we have
now we have
Now we have
It makes a cycloid pattern in parametrics if that's what you're asking~
