<h2>
Answer:</h2>
1.77V
<h2>
Explanation:</h2>
The electromotive force voltage (E) in a cell, is related to the lost voltage (
) and the terminal voltage (
) as follows;
E = -
Where;
The lost voltage () is the product of the internal resistance (r) of the cell and current (I) in the cell. i.e
= I x r
<em>Substitute </em><em> = I x r into equation (i) as follows;</em>
E = - (I x r) ----------------------(ii)
<em>According to the question;</em>
E = 1.54V
I = 2.15A
r = 0.105Ω
<em>Substitute these values into equation(ii) as follows;</em>
1.54 = - (2.15 x 0.105)
1.54 = - (0.22575)
1.54 = - 0.22575
<em>Solve for </em><em>;</em>
= 1.54 + 0.22575
= 1.54 + 0.22575
= 1.77V
Therefore, the terminal voltage of the cell is 1.77V
Explanation:
If it doesn't specify vertical or horizontal, that means it wants you to find the total velocity. You can do that using Pythagorean theorem:
v² = vₓ² + vᵧ²
Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density
<h3>What is anomalous expansion of water?</h3>
Anomalous expansion of water is a property of water in which water expands instead of contracting.
- Anomalous expansion of water makes water less dense.
- The major effect of this anomalous expansion it will still remain less dense and at the surface of water.
- Interestingly, this expansion occurs when it is cooled from 4°C to 0°C.
