Answer:
Blood
Explanation:
Homogenous means the same type and a box with toys, spaghetti and meatballs, and trail mix all have variety.
Answer:
78 V
Explanation:
The figure of the circuit is missing: find it in attachment.
At the beginning, the switch is in the position "a", so the current flows from the battery through the resistor and the capacitor. So, the capacitor charges.
The final charge on the capacitor is given by:
where
is the capacitance
is the final potential difference across the the capacitor (equal to that of the battery)
So,
Later, the switch is moved to position b, so now the capacitor will discharge through the resistor. As a result, the current in the circuit follows the law
where
is the resistance
And according to Ohm's law, the voltage across the resistor is given by
Therefore,
However, (potential difference across the battery), so
Therefore, substituting
t = 1.7 ms = 0.0017 s
We find:
<span>the power supplied to the motor by the fuel cell is 0.31 watts.

The current , I is 0.5 A.
Voltage, V is 0.43 V
From ohm's law: V = IR
Thus, R = 0.43/0.5 = 0.86Ω
Now, Power =
R
= 0.5 ×0.5×0.86
= 0.215 W
