<h3><u>Answer;</u></h3>
<em>The voltage is zero</em>
<h3><u>Explanation;</u></h3>
- <em><u>Voltage is the potential difference between two points in a circuit or the electromotive force in a given circuit and is expressed in volts (V). </u></em>
- Voltage is measured by a device called voltmeter that is always connected in parallel with the current source.
- <em><u>When voltage is measured between two points on a wire in a circuit with zero or no resistance in between the two points then the voltage will be zero</u></em><em>. </em>From the ohm's Law, voltage is given the product of resistance and current and thus if the resistance is zero then the voltage will be zero.
The correct answer is A.
The cell membrane consists of a phospholipid bilayer with embedded proteins. Sometimes molecules are just too big to easily flow across the plasma membrane or dissolve in the water so that they can be filtered through the cell membrane. In these cases , the cells must put out a little energy to help get molecules in and out of the cell.
The proteins embedded in the plasma membrane form channels through which other molecules can pass. Some proteins act as carriers, that is they are 'paid" in energy to let a molecule attach to itself and then transport that molecule inside the cell. This is called active transport.
Answer:
b
Explanation:
An insulator does not transfer thermal or electrical energy but a conductor does
