Answer:
V=IR
since the circuit is parallel both resistor have same voltage and different current value according to OHMs law.
total resistance in parallel=
1/R=1/R1+1/R2+...+1/Rn
since we have two resistor in parallel
Rt=R1R2/R1+R2
2*4/2+4=4/3 ohms
I=V/R
12/4/3=36/4=9Amp
OR
I=12/2=6amp
I=12/4=3amp
total current
I=6+3
9amp
Answer:
r = 102.43 m
Explanation:
Newton's second law for this case is
F = ma
Where the acceleration is centripetal
a = v² / r
r = v² / a
They indicate that the radial acceleration is 8.45 g
r = v² / 8.45 g.
r = 92.1² / 8.45 9.8
r = 102.43 m
The answer of this question is D. All of the above
Acceleration happen when an obeject change its velocity. It has nothing to do with speed.
The huge misconception about acceleration is when we thought it only aply if we increase our speed ( in a sport match, sportcaster often describe acceleration as an increase in players speed)
slower, faster, right , left, it does not matter, as long as that object change its velocity, it accelerates
