The electric current intensity (I) is the amount of electricity or electric charge (Q) that circulates through a circuit in the unit of time (t). Mathematically it can be described as
Our values are,
Replacing we have that the charge is
Therefore the amount of electric charge transported is 0.2137 Coulombs
Definitely A. Hope I helped you out
Answer:
rock A:
rock B:
g=9.81m/s^2
Explanation:
<u>Kinematics equation:</u>
in our case the acceleration is the gravity and it has a negative direction.
a=-g
<u>rock A, yo=90m, Voy=0m/s:</u>
<u>rock B, yo=0m, Voy=30m/s:</u>
That could be either a reflecting telescope, or else a periscope.
