Answer:
The building is 61.19 m tall, approximately.
Explanation:
From the parabollic movement trayectory equation,
where H is the initial height of the ball and 
and 
the inital velocities in the vertical and horizontal direction, respectively; we have
.
In this case, the ball landed at the coordinates 
, so
.
When balanced forces act upon an object, the object does not move. But when unbalanced forces act on it, it does.
The current is defined as the ratio between the charge Q flowing through a certain point of a wire and the time interval,
:
First we need to find the net charge flowing at a certain point of the wire in one second,
. Using I=0.92 A and re-arranging the previous equation, we find
Now we know that each electron carries a charge of
, so if we divide the charge Q flowing in the wire by the charge of one electron, we find the number of electron flowing in one second:
The correct answer among the choices above is option C. <span>Beryllium, Be, and chlorine, Cl, form a binary ionic compound with a one-to-two ratio of beryllium ions to chloride ions.</span> The chemical formula for the compound of beryllium and chlorine is BeCl2.
Answer:
I’m pretty positive that it’s 3 seconds
Hope this helps!
