Answer:
0.33 Amp
8 Watts
Explanation:
The current through the 12 Ω resistor will be given by Ohm's law:
4 V / 12 Ω = 1/3 Amp ≈ 0.33 Amp
The power dissipated on the 2 Ω resistor can be calculated via the formula:
which gives:
4^2 / 2 = 8 Watts
Answer:
B
Explanation:
Adding a dopant is correct on edge.
Answer:
Facilitated diffusion and active transport both utilize proteins to transport substances across membranes. Differences between active transport and facilitated diffusion 1. Active transport requires an input of energy, usually ATP, while facilitated transport does not.
Answer:
The potential difference between the places is 0.3 V.
∴ 1st option i.e. 0.3V is the correct option.
Explanation:
Given
Work done W = 3J
Amount of Charge q = 10C
To determine
We need to determine the potential difference V between the places.
The potential difference between the two points can be determined using the formula
Potential Difference (V) = Work Done (W) / Amount of Charge (q)
or
![\:V\:=\:\frac{W}{q}](https://tex.z-dn.net/?f=%5C%3AV%5C%3A%3D%5C%3A%5Cfrac%7BW%7D%7Bq%7D)
substituting W = 3 and q = 10 in the formula
![V=\frac{3}{10}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B3%7D%7B10%7D)
V
Therefore, the potential difference between the places is 0.3 V.
∴ 1st option i.e. 0.3V is the correct option.
