Explanation :
It is given that,
Potential energy,
Power dissipated,
We know that the power dissipated is given by :
I is the current passing through the phone.
or
I = 0.018 A
Hence, the current that passes through the phone is (1) 0.018 A.
Answer:
h2 = 0.092m
Explanation:
From a balance of energy from point A to point B, we get speed before the collision:
Solving for Vb:
Since the collision is elastic, we now that velocity of bead 1 after the collision is given by:
Now, by doing another balance of energy from the instant after the collision, to the point where bead 1 stops, we get the distance it rises:
Solving for h2:
h2 = 0.092m
