V = IR
Where v is voltage I is current and r is resistance
So
V = 9
R = 12
V/R = I
9/12 = I
I = 0.75 A

Answer:
Explanation:
As we projected the balloon at speed vo at an angle of 29 degree
so the two component of velocity is given as
now we know that in x direction we have
in y direction we have
now we have
Answer:
<em>t = 1.02 s</em>
Explanation:
friction = 0 N (no slipping)
downward force along the inclined plane = F = mgsin(30.8)
F = ma
⇒ a = 9.81 sin(30.8)
a = 5.02 m/s^2
now we have
displacement = s = 2.6 m
acceleration = a = 5.02m/s^2
initial velocity = Vi = 0m/s
time = t = ?
<u>APPLYING THE 2ND EQUATION OF MOTION:</u>
<em> S = (Vi)(t)+0.5at^2</em>
<em>2.6 = 0(t) + 0.5 * 5.02 * t^2</em>
<em>t = 1.02 s</em>
