Answer:
1.5cm
Explanation:
The place where the bead will come to rest is the place where the force between the left charge and the bead is the same, but in opposite direction, as he force between the right charge and the bead.

Also:


So, we replace and simplify. Notice that the charges and the Coulomb constant will cancel:


But the only solution that would place the bead on the wire is 0.015m or 1.5cm, so this is our answer.
Answer:
<em>The thermal energy dissipated in A would be twice that in B</em>
Explanation:
Resistor B (RB)= R
Resistor A (RA)= 2 R
When they are connected in series the equivalent Resistance in the circuit would be;
Equivalent resistance = RA +RB = R + 2 R = 3 R;
From ohms law I = V/R
I = V/3 R
Now the thermal energy is the power dissipated by the circuit and can be obtained thus;
P =
Then,

Therefore Pa : Pb = 2: 1, this means that the thermal energy dissipated in A would be twice that in B
Answer:
Blood absorbs nutrients and the waste products of cells. It carries waste away from cells and pumps nutrients through the whole body.
